FIG2 shows a flow chart of a method for monitoring and processing differential settlement of a widened embankment according to an embodiment of the present invention.

As shown in FIG. 2 , the monitoring and processing method for differential settlement of widened embankments of this embodiment includes operations S210 to S260 .

In operation S210, a plurality of image data and measuring point data corresponding to a target embankment are acquired using a target monitoring device, wherein the target monitoring device includes a first monitoring device and a second monitoring device, and the measuring point data represent settlement data of cross-sectional measuring points corresponding to the target embankment.

According to an embodiment of the present invention, the image data may be radar image data acquired by a first monitoring device, which may be a satellite monitoring device. The measurement point data may be ground point data corresponding to a target embankment acquired by a second monitoring device, which may be a ground monitoring device.

In operation S220, a first settlement result is determined based on the measurement point data.

According to an embodiment of the present invention, the measuring point data may be settlement data of a cross-section monitoring point of the target embankment obtained by monitoring using a second monitoring device (e.g., a level meter). The first settlement result may be a settlement result of a cross-section monitoring point of the target embankment obtained by inputting the measuring point data into a settlement calculation model or using a related difference algorithm.

In operation S230 , the plurality of image data are processed based on a preset processing rule to generate an initial interference image data pair.

According to an embodiment of the present invention, image data may include first image data (primary image data) and second image data (secondary image data). The primary image may be characterized as an image selected as a reference in a time series, and other images are registered and matched with it to achieve monitoring of surface changes. The selection of the primary image usually takes into account factors such as stable surface conditions, less cloud cover, and high observation quality. The secondary image is relative to the primary image and is used to compare with the primary image to monitor changes in the surface. The secondary image needs to be registered with the primary image so that the two images correspond in geographic coordinates in order to monitor changes. Both the primary image and the secondary image are part of the image sequence and are used to monitor and analyze surface changes.

In operation S240 , the initial interference image data pair is updated based on a first updating rule to generate a target interference image data pair, wherein a coherence degree value of the target interference image data pair is greater than a coherence degree value of the initial interference image data pair.

According to an embodiment of the present invention, the first update rule may include a terrain phase correction rule and a phase unwrapping rule. The terrain phase may characterize the phase change caused by the influence of the terrain on the propagation of radar waves. Phase unwrapping may be used to extract ground elevation information from the interference phase. Phase unwrapping methods may include minimum cost flow method, connected region-based phase unwrapping (Region Growing) and quality-guided phase unwrapping (Quality-Guided). The specific method is not limited here, and the phase path with the minimum noise sensitivity is selected. The target interference image data pair may characterize the image data pair after terrain phase correction and phase unwrapping are performed on the initial interference image data pair.

According to an embodiment of the present invention, coherence can be used to measure an important indicator of image data, reflecting the degree to which the radar waves collected twice remain consistent when reflected on the surface. The coherence degree value of the target interference image data pair updated by using the first update rule is greater than the coherence degree value of the initial interference image data pair.

In operation S250, the target interference image data pair is input into a settlement monitoring model, and a second settlement result corresponding to the target embankment is output.

According to an embodiment of the present invention, the settlement monitoring model can be used to monitor the average rate of surface deformation of each pixel point on the surface of the target embankment. In image data processing, inversion can represent the process of using the image data obtained from monitoring to derive the physical parameters or characteristics of targets such as the surface or atmosphere. Through inversion, information such as the terrain elevation, surface cover type, soil moisture, and vegetation biomass of the surface can be obtained, and it can also be used to derive parameters such as water vapor content and temperature in the atmosphere.

In a feasible embodiment, the second settlement result corresponding to the target embankment can be inverted through the acquisition time of the main image data, the acquisition time of the secondary image data, the time interval between the acquisition of the main and secondary image data, and the phase change of the target interference image data in the image data.

In operation S260, the second settlement result is updated based on the second update rule and the first settlement result to generate a third settlement result corresponding to the target embankment.

According to an embodiment of the present invention, the second update rule may include an atmospheric correction rule and a geocoding rule. The atmospheric correction rule may characterize a rule for calculating and correcting the atmospheric delay of each pixel on the surface of the target embankment by utilizing the relationship between meteorological parameter data and atmospheric delay. The geocoding rule may characterize a rule for finally obtaining a deformation result in a standard coordinate system in the process of projecting the second settlement result from a radar coordinate system to an image or data set in a standard coordinate system (a coordinate system with geographic coordinates, such as longitude and latitude). The third settlement result may be generated by updating the second settlement result based on the atmospheric correction rule, the geocoding rule and the first settlement result.

In a feasible embodiment, the method of determining the first settlement result may include: based on multiple measuring point data of the widened embankment section (such as data inside the embankment and at the bottom of the embankment), recording and analyzing each set of measuring point data, and counting the settlement data of key measuring points of each section; thereby, the inverse distance weighted interpolation method or related model simulation can be used to simulate the measuring point data of the entire target embankment, and then the first settlement result can be calculated.

In a feasible embodiment, the inverse distance weighted interpolation method can be used to calculate the measuring point data to obtain the first settlement result of the entire target embankment, including: firstly, monitoring multiple monitoring points 1, 2, 3, ..., n of the target embankment is performed, and _f1 , _f2 , _f3 , ..., _fn are the settlement data of the actual monitoring points connected in series by multiple hydraulic static levels; the settlement data _F1 , _F2 , _F3 , ..., _Fn of the settlement points around the measuring point are obtained by interpolation method. The calculation method of the first settlement result _Fj of the target embankment is specifically shown in the following formulas (1)-(2):

(1);

Among them, w _i is the weight of the known point i, and h is the distance between the known monitoring point and the settlement measuring points around the point to be determined.

(2);

Among them, j is the location of the settlement point around the unknown point to be calculated; i is the location of the settlement measurement point around the known point; _Fj and _fi represent the corresponding settlement values. The settlement data of the unknown points around the internal section monitoring points of the target embankment at different heights are obtained by the inverse distance weighted interpolation method, and then the settlement data of the entire embankment widening is simulated. Then, the relationship of the internal settlement curve of the embankment widening is obtained through post-processing software, which can intuitively observe the differential settlement of the embankment widening.

In a feasible embodiment, the target embankment is comprehensively monitored by the first monitoring device (satellite monitoring device) and the second monitoring device (ground monitoring device). After the settlement results (third settlement results) including different depth monitoring points and different embankment surface monitoring points are generated, the third settlement results can be displayed in a data intuitive graph, so that the settlement of the full cross-section of the target embankment widening can be obtained. The differential settlement threshold can be set according to the actual situation of the embankment widening. For example, the settlement of the widened embankment on the general road section is not more than 15cm, meeting the requirements that the increase in the transverse slope of the embankment is not more than 0.5% or the change in the longitudinal slope caused by the differential settlement is not more than 0.4%. Early warning is issued for settlement points close to the differential settlement threshold. It should be noted that the differential settlement threshold can be set according to the actual situation and specific project, and is not specifically limited here.

In a feasible embodiment, after the target embankment is monitored by ground monitoring equipment and the settlement results of the cross-sections at monitoring points at different depths are generated, the surface settlement estimation results of the monitoring point section of the widened embankment can be generated based on the settlement results of the monitoring point section; thereby, the surface settlement estimation results can be matched with the third settlement results, and if the error between the two settlement results is less than an error threshold (the error threshold represents that the error meets the corresponding specification), the data can be combined, that is, within a certain target range of the cross-section of the section (for example, the fill properties of the widened embankment are consistent), the surface settlement data of the widened embankment can be obtained only by satellite monitoring equipment, and then the settlement results of the section within the target range are obtained based on the surface settlement data obtained by trial and error combined with the settlement detection model; thereby, the settlement results of the section within a certain target range can be inferred by using the settlement results of the widened embankment section within the target range, thereby further improving the monitoring efficiency and monitoring range of differential settlement of the target embankment. According to an embodiment of the present invention, a target embankment is continuously monitored around the clock by multiple target monitoring devices to obtain multi-temporal image data and measuring point data, and a first settlement result and an initial interference image data pair are generated, so that the initial interference image data pair is updated based on a first update rule to generate a target interference image data pair with a higher coherence degree value, thereby reducing the number of interference image data pairs while improving the data quality of the interference image data pairs, reducing system resource consumption, and using the streamlined target interference image data pairs and the settlement prediction model to obtain a second settlement result, and then using the second update rule and the first settlement result to further update and optimize the second settlement result, and finally obtain a third settlement result. Since the third settlement result is obtained based on the comprehensive monitoring results of multi-dimensional and multi-temporal of different monitoring devices, the accuracy of the monitoring results is improved.

According to an embodiment of the present invention, an initial interference image data pair is updated based on a first updating rule to generate a target interference image data pair, including: acquiring ground distance data and reference data corresponding to the initial interference image data pair, wherein the ground distance data represents distance data between a target embankment surface feature point and a first monitoring device, and the reference data represents elevation data of the target embankment surface feature point; determining an offset value of the initial interference image data pair based on the ground distance data and the reference data; and updating the initial interference image data pair based on the offset value and the first updating rule to generate a target interference image data pair.

According to an embodiment of the present invention, the first update rule may include a terrain phase correction rule and a phase unwrapping rule. In the image data, the terrain phase can be characterized as the phase ambiguity or phase offset caused by the radar wave when the terrain undulation changes, so terrain phase correction is required. Since the phase data is affected by multiple factors (such as terrain undulation, atmospheric interference, etc.), the phase data usually circulates in the range of [-π, π], which leads to phase entanglement. Phase unwrapping is to unwrap these phase data from the cyclic range to a continuous phase surface.

The ground distance data can represent the geometric distance between the ground target (such as point A on the embankment widening surface) and the satellite monitoring equipment. The benchmark data can represent the reference information of the ground elevation, and the elevation information of the benchmark map can be mapped to the image data.

FIG. 3 is a schematic diagram showing a terrain correction method according to an embodiment of the present invention.

As shown in Figure 3, the satellite monitoring equipment (radar) is located at S ₁ and S ₂ respectively. The flight altitude of radar S ₁ is H, the baseline distance between radar S ₁ and radar S ₂ is B, the target embankment widening surface and the slope are undulating, and the height of point A on the embankment widening surface relative to the ground reference plane is set to h. The slant distance from radar S ₁ to point A is R ₁ , and the slant distance from radar S ₂ to point A on the target embankment widening surface is R _2. In the orthographic projection image, the pixel point A ₀ corresponding to the target point A is the same as point C when the side-view radar is converted to the oblique ground due to the influence of the undulating terrain. Suppose the slant distance from radar S ₁ to point C is r ₁ , then r ₁ = R ₁ , the orthographic projection of radar S ₁ from point O to point A ₀ and point C are L _OA0 and L _OC respectively, the incident angle of radar S ₁ monitoring point A is set to θ, and the baseline horizontal angle is ɑ. Then the slant range difference δR between the slant range _R1 and the slant range _R2 , the radar side angle β, and the slant range _R1 from the radar _S1 to point A can be calculated, as shown in the following formulas (3)-(5):

(3);

(4);

(5);

In ΔS ₁ S ₂ A, the cosine theorem of the triangle and the relationship between the sides show that the distances from the radar S ₁ orthographic projection point O to points A ₀ and C are L _OA0 and L _OC respectively, as shown in the following formulas (6)-(8):

(6);

(7);

(8);

Considering that δθ is extremely small and can be ignored relative to θ, the image offset value ∆L of the position of point A in the ground distance map (ground distance data) relative to the reference map (reference data) can be corrected. ∆L is specifically shown in the following formula (9):

(9);

Furthermore, the slope range difference δR caused by the elevation of the target widened embankment is converted into an interferometric phase model to obtain the terrain phase ψ _top , as shown in the following formula (10):

(10);

Finally, the digital elevation model data obtained by the satellite monitoring equipment can be converted from the earth coordinate system to the oblique earth coordinate system to eliminate or reduce the influence of the earth's curvature and terrain tilt on the terrain. By substituting ΔL, the conversion based on elevation information is realized to correct the influence of terrain phase.

According to an embodiment of the present invention, generating a highly coherent target interference image data pair through terrain phase correction rules and phase unwrapping rules is crucial for obtaining accurate interference patterns and deformation monitoring, which can improve the quality and reliability of the data and provide a more reliable foundation for subsequent data analysis and application.

According to an embodiment of the present invention, a target interference image data pair is input into a settlement monitoring model, and a second settlement result corresponding to a target embankment is output, including: selecting a target baseline data pair from the target interference image data pair based on preset screening rules; and inputting the target baseline data pair into the settlement monitoring model to generate a second settlement result corresponding to the target embankment.

According to an embodiment of the present invention, the baseline data can characterize the change in the position of the satellite monitoring device between two observations, and the length of the spatial baseline can be determined by the orbital position and attitude change of the satellite monitoring device during the two monitoring periods. The preset screening rule can be a rule selected according to the length of the spatial baseline, and the target baseline data pair can be selected by selecting a baseline group with a shorter spatial baseline between adjacent moments as the target baseline, and then the acquisition time _tn of the main image data in the image data, the acquisition time tn _-1 of the secondary image data, the time interval δt between the acquisition of the primary and secondary image data, and the phase change δψ of the target interferometric image data pair can be used to invert the second settlement result, that is, the average surface deformation rate _vn of each pixel point on the surface of the target embankment, as shown in the following formula (11):

(11);

Wherein, ψ _n is the terrain phase of the primary image data, and ψ _n-1 is the terrain phase of the secondary image data.

According to an embodiment of the present invention, by selecting a baseline group with shorter spatial baselines between adjacent moments as the target baseline to generate the average rate of surface deformation for each pixel point on the target embankment surface, a shorter spatial baseline means that the position change of the satellite between two observations is smaller, which helps to reduce the influence of atmospheric and terrain effects on the interferometric phase. Atmospheric and terrain effects are common sources of error in satellite monitoring. Selecting a shorter baseline can reduce these errors and improve the measurement accuracy of surface deformation.

According to an embodiment of the present invention, the second update rule includes an atmospheric correction rule and a geocoding rule; wherein, the second settlement result is updated based on the second update rule and the first settlement result to generate a third settlement result corresponding to the target embankment, including: updating the second settlement result based on the atmospheric correction rule to generate an atmospheric corrected settlement result; mapping the atmospheric corrected settlement result to the target coordinate system based on the geocoding rule to generate a mapped settlement result; and updating the mapped settlement result using the first settlement result to generate a third settlement result corresponding to the target embankment.

According to an embodiment of the present invention, taking into account the existence of atmospheric delay in satellite monitoring, the atmospheric delay is caused by reflection, refraction and other effects of the troposphere, including static delay and wet delay. Static delay; static delay is mainly affected by air pressure and temperature, changes smoothly in space, and changes slowly over time, showing good periodicity; wet delay is mainly affected by water vapor partial pressure and temperature, so it is necessary to perform atmospheric correction on the second deposition result to generate an atmospheric corrected deposition result.

In a feasible embodiment, the second settlement result is projected from the radar coordinate system to an image or data set of the WGS-84 coordinate system using geocoding rules, thereby obtaining the differential settlement deformation result of the target embankment in the WGS-84 coordinate system.

According to an embodiment of the present invention, the second update rule also includes a filtering rule; wherein, before the second sedimentation result is updated based on the atmospheric correction rule and the atmospheric correction sedimentation result is generated, it includes: filtering the second sedimentation result using the filtering rule to generate a first filtered sedimentation result and a second filtered sedimentation result; and merging the first filtered sedimentation result and the second filtered sedimentation result to generate a filtered second sedimentation result.

According to an embodiment of the present invention, the filtering rule can represent the rule of using a filter to remove the atmospheric phase in the satellite image data processing, which can include a high-pass filtering rule and a low-pass filtering rule. High-pass filtering can reduce the influence of the low-frequency part in the image data, making the high-frequency part (such as details) more prominent; low-pass filtering can retain the low-frequency part in the image data and suppress the high-frequency part. In removing the atmospheric phase, low-pass filtering can help smooth the image, remove high-frequency noise and details, and highlight the low-frequency atmospheric influence.

In a feasible embodiment, the method of filtering the second sedimentation result through filtering rules may include: using a low-pass filter to filter the original image, smoothing the image, removing high-frequency noise and details, retaining low-frequency atmospheric effects, and obtaining a low-pass filtered image; thereby subtracting the low-pass filtered image from the original image to obtain an approximate image with low-frequency atmospheric effects (i.e., the first filtering sedimentation result); then applying a high-pass filter to perform high-pass filtering on the low-frequency image, highlighting the high-frequency part of the image, retaining detail information, and obtaining a high-pass filtered image, and subtracting the original image from the high-pass filtered image to obtain an approximate image with high-frequency atmospheric effects (i.e., the second filtering sedimentation result); on this basis, merging the low-frequency and high-frequency images to obtain an image with the atmospheric phase effects removed.

According to an embodiment of the present invention, the second settlement result is updated based on the atmospheric correction rules to generate an atmospheric corrected settlement result, including: using meteorological monitoring equipment to obtain meteorological data corresponding to the target embankment within the target time period; generating atmospheric delay data corresponding to the target embankment based on the meteorological data and the meteorological simulation model; and updating the second settlement result based on the atmospheric delay data and the atmospheric correction rules to generate an atmospheric corrected settlement result.

According to an embodiment of the present invention, meteorological monitoring equipment, such as meteorological radar, meteorological satellite, air quality monitoring equipment, thermometer, hygrometer, barometer, precipitation meter and anemometer, etc., can be used to obtain meteorological data corresponding to the target embankment in the target time period, and the meteorological data may include temperature data, air pressure data and humidity data. A meteorological simulation model (such as Weather Research and Forecasting (WRF) model) can be used to generate meteorological delay data, and the atmospheric delay data and atmospheric correction rules are used to update and optimize the second settlement result to obtain an atmospheric correction settlement result.

According to an embodiment of the present invention, meteorological data includes temperature data, air pressure data and humidity data; wherein, atmospheric delay data corresponding to the target embankment is generated based on the meteorological data and the meteorological simulation model, including: inputting the temperature data, air pressure data and humidity data corresponding to the target embankment within the target time into the meteorological simulation model, outputting the simulation results corresponding to the meteorological data; and determining the atmospheric delay data corresponding to the target embankment based on the simulation results.

According to an embodiment of the present invention, a Weather Research and Forecasting (WRF) model is used to establish a mathematical relationship between meteorological variables through the meteorological data obtained by monitoring. The atmospheric data such as air temperature, air pressure, and temperature obtained by the meteorological collection module are used to simulate the changes in time and space of data such as temperature, humidity, air pressure, and wind field in the atmosphere to obtain a detailed description of the atmospheric field. The atmospheric delay field at each moment and each spatial point can be calculated using the WRF simulation results. The atmospheric delay field in the WRF simulation results is aligned with the second deposition result, and spatial interpolation is performed. This can be achieved through geographic coordinate conversion and interpolation algorithms to ensure the spatial consistency and matching of the two. Atmospheric correction of the second deposition result is performed to obtain an atmospheric corrected deposition result.

According to an embodiment of the present invention, the atmospheric correction rules include coordinate transformation rules and interpolation algorithms; wherein, the second sedimentation result is updated based on the atmospheric delay data and the atmospheric correction rules to generate an atmospheric correction sedimentation result, including: based on the coordinate transformation rules, the atmospheric delay data and the second sedimentation result data are aligned in the target coordinate system to generate an alignment result; and the alignment result is interpolated using an interpolation algorithm to generate an atmospheric correction sedimentation result.

According to an embodiment of the present invention, in order to ensure that the simulation results output by the meteorological simulation model are consistent with the geographic coordinate system used by the image data, the coordinate transformation rules (such as raster transformation and projection coordinate transformation) can be used to match the atmospheric delay data and the image data on the same spatial grid to generate a registration result; on this basis, the interpolation method (such as bilinear interpolation, Kriging interpolation, radial basis function interpolation (RBF)) can be used to match the atmospheric delay data in the WRF simulation results with the image data on the same spatial grid, thereby generating an atmospheric correction deposition result.

According to the embodiments of the present invention, the influence of atmospheric delay on image data can be effectively removed, the spatial resolution of data can be improved, the interpretation and analysis of surface deformation can be improved, and multi-source data fusion can be achieved, so as to more accurately obtain the differential settlement results of widened embankments.

According to an embodiment of the present invention, multiple image data are processed based on preset processing rules to generate an initial interference image data pair, including: selecting first image data and second image data from the multiple image data, wherein the first image data and the second image data are matched and aligned in time dimension and space dimension; and pairing the first image data and the second image data based on the preset processing rules to generate an initial interference image data pair.

According to an embodiment of the present invention, there is a temporal correlation between the primary image and the secondary image, and by comparing the difference between the two, the changes in the ground surface can be revealed. The primary image is a reference image in a time series, which is used to align and match other images; while the secondary image is relative to the primary image and is acquired later than the primary image. The time interval between the primary image and the secondary image, that is, the longest time interval (maximum time baseline) between two radar observations can be determined according to actual conditions and is not limited here. The preset processing rules may include pairing processing rules. The pairing processing rules are to pair the primary image and the secondary image acquired in different time periods to generate interference image data pairs, and then the surface changes of the target embankment in different time periods can be captured according to the interference image data pairs with different time baselines.

In a feasible embodiment, the operation of pairing the first image data and the second image data to generate an initial interference image data pair may include: selecting a secondary image from an image set that has a suitable time baseline with the primary image; and accurately aligning the secondary image with the primary image to ensure that the two images are aligned in space and time; thereby obtaining the phase difference between the two images through a phase resolution method (such as a multi-parallax method or a frequency domain method) to generate an interference image; filtering and phase unwrapping the interference image to reduce noise and unwrap the phase; and then combining the filtered and phase unwrapped interference image with the primary image to generate multiple initial interference image data pairs.

After the hydraulic static level 420 is debugged, it is buried in the original embankment 451. The newly built embankment 452 is placed on the same plane and the hydraulic static level 420 is buried. The first hydraulic static level 421 is taken as the reference point and placed in the protection box outside the widened embankment. Each hydraulic static level 420 is connected to the liquid storage tank 430 through the liquid pipe 411, the air pipe 412 and the wire pipe 413. During monitoring, the elevation of the hydraulic static level 420 relative to the base point changes, causing the pressure of the liquid to change in the process. The hydraulic static level 420 converts this change into an electrical signal to provide the measurement point data of the settlement monitoring point, and uses the data acquisition component 460 to store, send and subsequently process the measurement point data. The power supply component 470 can use a solar charging panel for autonomous power supply. The solar charging panel can be set on the outside of the widened embankment to store electrical energy for use by the equipment.
