Fig. 2 shows a flowchart of the monitoring and processing method for differential 500988 settlement of widened embankments according to an embodiment of the invention.
As shown in FIG. 2, the monitoring and processing method for differential settlement of widened embankments according to this embodiment includes operations S210 to
S260.
At operation S210, acquiring multiple image data and measurement point data corresponding to a target embankment by using target monitoring equipment, where the target monitoring equipment includes a first monitoring device and a second monitoring device, and the measurement point data represents cross-sectional measurement point settlement data corresponding to the target embankment.
According to an embodiment of the invention, the image data may be radar image data acquired by the first monitoring device, and the first monitoring device may be satellite monitoring equipment. The measurement point data may be ground point data corresponding to the target embankment acquired by the second monitoring device, and the second monitoring device may be ground monitoring equipment.
At operation S220, determining a first settlement result based on the measurement point data.
According to an embodiment of the invention, the measurement point data may be settlement data of cross-sectional measurement points of the target embankment monitored by the second monitoring device (for example, a levelling instrument). The first settlement result may be a settlement result of cross-sectional measurement points of the target embankment obtained by inputting the measurement point data into a settlement calculation model or using a related interpolation algorithm.
At operation S230, processing the multiple image data based on preset processing rules to generate initial interferometric image data pairs.
According to an embodiment of the invention, the image data may include first image data (main image data) and second image data (secondary image data). The main image data may be characterized as the image selected as a reference in the time series, and other images are registered and matched with it to achieve surface change monitoring.
The selection of the main image usually considers factors such as stable surface conditions, less cloud cover, and high observation quality. The secondary image data is relative to the main image data and is used to compare with the main image data to monitor surface changes.
The secondary image data needs to be registered with the main image data so that 500988 the two images correspond in geographic coordinates to enable change monitoring. Both the main image data and the secondary image data are part of the image sequence and are used for surface change monitoring and analysis.
At operation S240, updating the initial interferometric image data pairs based on a first update rule to generate target interferometric image data pairs, where the coherence degree value of the target interferometric image data pairs is greater than that of the initial interferometric image data pairs.
According to an embodiment of the invention, the first update rule may include a terrain phase correction rule and a phase unwrapping rule. The terrain phase may be characterized as the phase change caused by the influence of terrain on radar wave propagation. Phase unwrapping may be used to extract ground elevation information from the interferometric phase, and the phase unwrapping methods may include the minimum cost flow method, region growing, and quality-guided phase unwrapping, and the specific method is not limited here, with the selection of the phase path with the least noise sensitivity as the criterion. The target interferometric image data pairs may be characterized as image data pairs obtained by performing terrain phase correction and phase unwrapping on the initial interferometric image data pairs.
According to an embodiment of the invention, coherence may be used as an important indicator to measure image data, reflecting the degree to which the radar waves reflected from the surface remain consistent during two acquisitions. By using the first update rule, the coherence degree value of the updated target interferometric image data pairs is greater than that of the initial interferometric image data pairs.
At operation S250, inputting the target interferometric image data pairs into a settlement monitoring model to output a second settlement result corresponding to the target embankment.
According to an embodiment of the invention, the settlement monitoring model may be used to monitor the average surface deformation rate of each pixel on the surface of the target embankment. In image data processing, inversion may be characterized as the process of deriving physical parameters or characteristics of the surface or atmosphere using the monitored image data. Through inversion, information such as surface elevation, surface cover type, soil moisture, and vegetation biomass may be obtained, and parameters such as water vapour content and temperature in the atmosphere may also be derived.
In a feasible embodiment, by using the acquisition time of the main image data, 600988 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 interferometric image data pairs, the second settlement result corresponding to the target embankment may be inverted.
At operation S260, updating the second settlement result based on a 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 invention, the second update rule may include an atmospheric correction rule and a geocoding rule. The atmospheric correction rule may be characterized as using the relationship between meteorological parameter data and atmospheric delay to calculate the atmospheric delay of each pixel on the surface of the target embankment and perform correction. The geocoding rule may be characterized as the process of projecting the second settlement result from the radar coordinate system to a standard coordinate system (a coordinate system with geographic coordinates, such as longitude and latitude) to finally obtain the deformation result in the standard coordinate system. 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 for determining the first settlement result may include: based on the measurement point data of multiple cross-sections of the widened embankment (for example, data inside the embankment and at the bottom of the embankment), recording and analysing the measurement point data of each cross- section, and statistically analysing the key measurement point settlement data of each cross-section; then, the inverse distance weighting interpolation method or related model simulation may be used to simulate the measurement point data of the entire target embankment, and then the first settlement result may be calculated.
In a feasible embodiment, the inverse distance weighting interpolation method may be used to calculate the measurement point data to obtain the first settlement result of the entire target embankment, including: first, monitoring multiple monitoring points 1, 2, 3, ..., N of the target embankment, and recording fi, fa, fs, ..., fn as the settlement data of the actual monitoring points connected in series by hydraulic static level gauges; using the interpolation method to obtain the settlement data F1, F2, F3, ..., Fn of the surrounding settlement points of the measurement points,
and the calculation method of the first settlement result F; of the target embankment 500988 is specifically as shown in the following formulas (1)-(2): a (1) where wi is the weight of the known point i, and h is the distance value between the known monitoring point and the surrounding settlement measurement points to be calculated
Qu (2) where | is the position of the surrounding settlement point to be calculated; i is the position of the surrounding settlement measurement points of the known point; Fj and fi represent the corresponding settlement values. By using the inverse distance weighting interpolation method, the settlement data of unknown points around the internal cross- sectional monitoring points of the target embankment at different heights may be calculated, and then the settlement data of the entire widened embankment may be simulated. Through post-processing software, the internal settlement curve relationship of the widened embankment may be obtained, and the differential settlement situation of the widened embankment may be visually observed.
In a feasible embodiment, after comprehensively monitoring the target embankment using the first monitoring device (satellite monitoring equipment) and the second monitoring device (ground monitoring equipment) to generate settlement results (third settlement results) including monitoring points at different depths and different embankment surface monitoring points, the third settlement result may be displayed in a data visualization chart, so that the full cross-sectional settlement situation of the target widened embankment may be obtained. A differential settlement threshold may be set according to the actual situation of the widened embankment, for example, the settlement of the widened embankment on general road sections should not exceed 15 cm, meeting the requirements that the increase in the cross slope of the embankment should not exceed 0.5% or the longitudinal slope change caused by differential settlement should not exceed 0.4%. For settlement points close to the differential settlement threshold, an early warning may be issued. It should be noted that the differential settlement threshold may be set according to the actual situation and specific engineering requirements, and is not limited here.
In a feasible embodiment, after monitoring the target embankment using ground 500988 monitoring equipment to generate cross-sectional settlement results of monitoring points at different depths, the surface settlement estimation results of the monitoring point section of the widened embankment may be generated based on the cross-sectional settlement results of the monitoring points; then, the surface settlement estimation results may be matched with the third settlement result. If the error between the two settlement results is less than the error threshold (the error threshold indicates that the error meets the corresponding specifications), the data may be combined, that is, within a certain target range of the cross-section of the embankment (for example, the filling material properties of the widened embankment are consistent), the surface settlement data of the widened embankment may be obtained only through satellite monitoring equipment, and then the cross-sectional settlement results within the target range may be obtained based on the real-time acquired surface settlement data and the settlement detection model: thereby, the settlement results of the nearby road sections may be inferred based on the cross-sectional settlement results of the widened embankment within a certain target range, further improving the monitoring efficiency and monitoring scope of the differential settlement of the target embankment. According to an embodiment of the invention, by using multiple target monitoring equipment to conduct all-weather continuous monitoring of the target embankment to obtain multi-temporal image data and measurement point data, and generating the first settlement result and initial interferometric image data pairs, thereby updating the initial interferometric image data pairs based on the first update rule to generate target interferometric image data pairs with a higher coherence degree value, thereby reducing the amount of interferometric image data pairs while improving the data quality of the interferometric image data pairs, reducing system resource consumption, and using the refined target interferometric image data pairs and the settlement prediction model to obtain the second settlement result, and further updating and optimizing the second settlement result based on the second update rule and the first settlement result to finally obtain the third settlement result, where the third settlement result is based on multi-dimensional and multi-temporal monitoring results from different monitoring equipment, thereby improving the accuracy of the monitoring results.
According to an embodiment of the invention, updating the initial interferometric image data pairs based on the first update rule to generate the target interferometric image data pairs includes: acquiring ground range data and reference data corresponding to the initial interferometric image data pairs,
where the ground range data represents distance data between surface feature 500988 points of the target embankment and the first monitoring device, and the reference data represents elevation data of the surface feature points of the target embankment; determining an offset value of the initial interferometric image data pairs based on the ground range data and the reference data; and updating the initial interferometric image data pairs based on the offset value and the first update rule to generate the target interferometric image data pairs.
According to an embodiment of the invention, the first update rule may include a terrain phase correction rule and a phase unwrapping rule. In the image data, the terrain phase may be characterized as the phase ambiguity or phase offset caused by the radar wave when the terrain undulates, 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 cycles within the range of [-TT, TT], which leads to phase wrapping. Phase unwrapping is the process of unwrapping these phase data from the cyclic range to a continuous phase surface.
The ground range data may be characterized as the geometric distance between a ground target (for example, point À on the surface of the widened embankment) and the satellite monitoring equipment. The reference data may be characterized as reference information of ground elevation, and the elevation information of the reference map may be mapped to the image data.
Fig. 3 shows a schematic diagram of a terrain correction method according to an embodiment of the invention.
As shown in FIG. 3, the satellite monitoring equipment (radar) is located at points S1 and Sa, respectively. The flight height of the radar at S1 is H, and the baseline distance between radar Sy and radar S» is B. The surface of the widened embankment and the slope have undulations, and the height of point A on the surface of the widened embankment relative to the ground reference surface is h. The slant range from radar S1 to point A is R1, and the slant range from radar Sz to point A on the surface of the widened embankment is Ra. In the orthographic projection image, the pixel point AO corresponding to point A is located at the same position as point C due to the influence of terrain undulation. In the side-looking radar slant-to-ground conversion, the pixel point corresponding to point A is the same as point C. Let the slant range from radar S4 to point
C be ry, then ri = Ry. The distances from the orthographic projection point O of radar Sy to points Ao and C are Loao and Loc, respectively.
Let the incident angle of radar S1 at point A be ©, and the horizontal angle of Ne 600988 baseline be a. Then, the slant range difference OR between slant ranges R1 and Ra, the side-looking angle B of the radar, and the slant range Rı from radar Si to point A may be calculated as shown in the following formulas (3) -(5):
HH
R= a)
SR=R ~R. à)
In AS1S2A, the cosine theorem of the triangle and the relationship between the sides may be used to obtain the distances Loao and Loc from the orthographic projection point
O of radar S4 to points Ao and C, respectively, as shown in the following formulas (6) -(8):
IRE (6)
Lou = KR, sm 0 (7)
Loc = Htan(0—00) ©
Considering that 56 is extremely small and may be ignored relative to ©, the image offset value AL of point À in the ground range map (ground range data) relative to the reference map (reference data) may be corrected, and AL is specifically as shown in the following formula (9): al = Los a Li =H * LL cos (9)
Further, the slant range difference OR caused by the elevation of the target widened embankment is converted into an interferometric phase model to obtain the terrain phase
Wtop, AS shown in the following formula (10):
A Â | cos6 X cos” à (10)
Finally, the digital elevation model (DEM) data obtained by the satellite monitoring equipment may be converted from the Earth coordinate system to the slant-to-ground coordinate system to eliminate or reduce the influence of the Earth's curvature and terrain tilt on the terrain. By substituting AL, the conversion based on elevation information is achieved, and the influence of the terrain phase is corrected.
According to an embodiment of the invention, by using the terrain phase correction 500988 rule and the phase unwrapping rule to generate target interferometric image data pairs with high coherence, it is crucial for obtaining accurate interferograms and deformation monitoring, which may improve the quality and reliability of the data and provide a more reliable basis for subsequent data analysis and applications.
According to an embodiment of the invention, inputting the target interferometric image data pairs into the settlement monitoring model to output the second settlement result corresponding to the target embankment includes: selecting target baseline data pairs from the target interferometric image data pairs based on a preset screening rule; and inputting the target baseline data pairs into the settlement monitoring model to generate the second settlement result corresponding to the target embankment.
According to an embodiment of the invention, the baseline data may be characterized as the change in the position of the satellite monitoring equipment between two observations, and the length of the spatial baseline may be determined by the orbital position and attitude changes of the satellite monitoring equipment during the two monitoring periods. The preset screening rule may be a rule based on the length of the spatial baseline, and the target baseline data pairs may be obtained by selecting baseline groups with shorter spatial baselines between adjacent times as the target baseline, and then the second settlement result, that is, the average surface deformation rate vn of each pixel on the surface of the target embankment, may be inverted based on the acquisition time tn of the main image data, the acquisition time tn of the secondary image data, the time interval ôt between the acquisition of the main and secondary image data, and the phase change dy of the target interferometric image data pairs, as shown in the following formula (11): vy = Va WV. PL C y 3 on [, CS [a 1 ot (11) where wn is the terrain phase of the main image data, and yn-1 is the terrain phase of the secondary image data.
According to an embodiment of the invention, by selecting baseline groups With 500988 shorter spatial baselines between adjacent times as the target baseline to generate the average surface deformation rate of each pixel on the surface of the target embankment, 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, and selecting shorter baselines may reduce these errors and improve the measurement accuracy of surface deformation.
According to an embodiment of the invention, the second update rule includes an atmospheric correction rule and a geocoding rule; where updating the second settlement result based on the second update rule and the first settlement result to generate the third settlement result corresponding to the target embankment includes: 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 a 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 the third settlement result corresponding to the target embankment.
According to an embodiment of the invention, considering the atmospheric delay phenomenon in satellite monitoring, atmospheric delay is caused by the reflection and refraction of the troposphere, including hydrostatic delay and wet delay; hydrostatic delay is mainly affected by pressure and temperature, and changes smoothly in space and 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 settlement result to generate the atmospheric-corrected settlement result.
In a feasible embodiment, by using the geocoding rule, the second settlement result is projected from the radar coordinate system to the WGS-84 coordinate system to obtain the differential settlement deformation result of the target embankment in the WGS-84 coordinate system.
According to an embodiment of the invention, the second update rule further includes a filtering rule; where updating the second settlement result based on the atmospheric correction rule to generate the atmospheric-corrected settlement result further includes: filtering the second settlement result using the filtering rule to generate a first filtered settlement result and a second filtered settlement result; and merging the first filtered settlement result and the second filtered settlement result to generate a filtered second settlement result.
According to an embodiment of the invention, the filtering rule may be characterized 00988 as using a filter to remove atmospheric phase in satellite image data processing, and may include a high-pass filtering rule and a low-pass filtering rule. High-pass filtering may reduce the influence of the low-frequency part of the image data, making the high- frequency part (such as details) more prominent; low-pass filtering may retain the low- frequency part of the image data while suppressing the high-frequency part. In removing atmospheric phase, low-pass filtering may help smooth the image, remove high- frequency noise and details, and highlight low-frequency atmospheric effects.
In a feasible embodiment, the method for filtering the second settlement result using the filtering rule may include: using a low-pass filter to filter the original image, smooth the image, remove high-frequency noise and details, and retain low-frequency atmospheric effects to obtain a low-pass filtered image; then subtracting the low-pass filtered image from the original image to obtain an approximate image of low-frequency atmospheric effects (i.e., the first filtered settlement result); then applying a high-pass filter to the low-frequency image to perform high-pass filtering, highlight the high- frequency part of the image, retain detail information, and obtain a high-pass filtered image, and subtracting the high-pass filtered image from the original image to obtain an approximate image of high-frequency atmospheric effects (i.e., the second filtered settlement result); on this basis, merging the low-frequency and high-frequency images to obtain an image with atmospheric phase effects removed.
According to an embodiment of the invention, by filtering the second settlement result, the accuracy of interferometric measurement may be improved, the monitoring ability of surface deformation signals of the widened embankment may be enhanced, the spatial resolution of surface deformation may be improved, the reliability of time series analysis may be enhanced, and the influence of surface elevation changes may be reduced, thereby improving the accuracy and reliability of differential settlement monitoring of the target embankment.
According to an embodiment of the invention, updating the second settlement result based on the atmospheric correction rule to generate the atmospheric-corrected settlement result includes: acquiring meteorological data corresponding to the target embankment within a target time period using a meteorological monitoring device; generating atmospheric delay data corresponding to the target embankment based on the meteorological data and a meteorological simulation model; and updating the second settlement result based on the atmospheric delay data and the atmospheric correction rule to generate the atmospheric-corrected settlement result.

By using a meteorological simulation model (such as the Weather
Research and Forecasting (WRF) model), meteorological delay data may be generated, and the second settlement result may be updated and optimized using the atmospheric delay data and the atmospheric correction rule to obtain the atmospheric-corrected settlement result.
According to an embodiment of the invention, the meteorological data includes temperature data, pressure data, and humidity data; where generating the atmospheric delay data corresponding to the target embankment based on the meteorological data and the meteorological simulation model includes: inputting the temperature data, pressure data, and humidity data corresponding to the target embankment within the target time period into the meteorological simulation model to output a simulation result corresponding to the meteorological data; and determining the atmospheric delay data corresponding to the target embankment based on the simulation result.
According to an embodiment of the invention, by using the Weather Research and
Forecasting (WRF) model, mathematical relationships between meteorological variables may be established based on the monitored meteorological data, and atmospheric data such as temperature, humidity, pressure, and wind fields may be simulated to obtain a detailed description of the atmospheric field. Using the WRF simulation results, the atmospheric delay field at each time and each spatial point may be calculated, and the atmospheric delay field in the WRF simulation results may be registered with the second settlement result and spatially interpolated. This may be achieved through geographic coordinate transformation and interpolation algorithms to ensure spatial consistency and matching between the two, and the atmospheric correction of the second settlement result may be performed to obtain the atmospheric-corrected settlement result.
According to an embodiment of the invention, the atmospheric correction rule 600988 includes a coordinate transformation rule and an interpolation algorithm; where updating the second settlement result based on the atmospheric delay data and the atmospheric correction rule to generate the atmospheric-corrected settlement result includes: registering the atmospheric delay data with the second settlement result data in the target coordinate system based on the coordinate transformation rule to generate a registration result; and performing interpolation processing on the registration result using the interpolation algorithm to generate the atmospheric-corrected settlement result.
According to an embodiment of the invention, to ensure that the simulation results output by the meteorological simulation model and the image data use the same geographic coordinate system, the coordinate transformation rule (such as grid transformation and projection coordinate transformation) may be used to register the atmospheric delay data with the image data on the same spatial grid to generate the registration result; on this basis, interpolation methods (such as bilinear interpolation,
Kriging interpolation, and radial basis function interpolation (RBF)) may be used to register the atmospheric delay data in the WRF simulation results with the image data on the same spatial grid, and then the atmospheric-corrected settlement result may be generated.
According to an embodiment of the invention, the influence of atmospheric delay on the image data may be effectively removed, the spatial resolution of the data may be improved, the interpretation and analysis of surface deformation may be enhanced, and multi-source data fusion may be achieved, thereby more accurately obtaining the differential settlement result of the widened embankment.
According to an embodiment of the invention, processing the multiple image data based on the preset processing rules to generate the initial interferometric image data pairs includes: selecting first image data and second image data from the multiple image data, where the first image data and the second image data are aligned in time and space dimensions; and pairing the first image data and the second image data based on the preset processing rules to generate the initial interferometric image data pairs.
According to an embodiment of the invention, there is a temporal relationship between the main image and the secondary image, and by comparing the differences between the two, surface changes may be revealed. The main image is the reference image in the time series, used for registering and matching other images; while the secondary image is relative to the main image and is acquired later than the main image.
The time interval between the main image and the secondary image, that is, NS 500988 maximum time interval (maximum time baseline) between two radar observations, may be determined according to the actual situation, and is not limited here. The preset processing rules may include pairing processing rules. The pairing processing rule is to pair the main image and the secondary image acquired at different time periods to generate interferometric image data pairs, and then the surface changes of the target embankment in different time periods may be captured based on the interferometric 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 the initial interferometric image data pairs may include: selecting the secondary image from the image set with a suitable time baseline relative to the main image; and precisely registering the secondary image with the main image to ensure that the two images are aligned in space and time; then, the phase difference between the two images may be obtained through phase analysis methods (such as multi-look methods or frequency domain methods) to generate the interferometric image; the interferometric image is filtered and phase unwrapped to reduce noise and unwrap the phase; then, the filtered and phase-unwrapped interferometric image is combined with the main image to generate multiple initial interferometric image data pairs.

Each hydraulic static level gauge 420 is connected through the liquid pipe 411, 93% 500988 pipe 412, and wire pipe 413 and then connected to the liquid storage tank 430.
During monitoring, the change in the relative elevation of the hydraulic static level gauge 420 relative to the reference point causes a change in liquid pressure, and the hydraulic static level gauge 420 converts this change into an electrical signal to provide measurement point data of the settlement monitoring point.
