Taking the application of the method to the video monitoring system in fig. 1 as an example, as shown in fig. 2, the method includes the following steps:

s101, obtaining the movement attribute information of the current picture; wherein the movement attribute information is used for reflecting the movement degree of the object in the current picture.

It should be noted that, in this embodiment, the type of the movement attribute information is not limited, and all factors that can reflect the movement degree of the object in the current screen may be used as the movement attribute information in this embodiment. Optionally, the movement attribute information includes at least one of an aspect ratio of the object in the current screen, an area ratio of the object, a movement distance of the object, and a movement speed of the object.

Optionally, the acquisition device may acquire the movement attribute information of the current picture, and the acquisition device may acquire the movement attribute information of the current picture through a movement detection algorithm in the acquisition device.

Optionally, as mentioned above, the threshold range set includes a primary alarm threshold range subset and a secondary alarm threshold range subset, and optionally, the number of the primary alarm threshold range subsets may be one or multiple; optionally, the number of the secondary alarm threshold range subsets may be one or multiple. The number of the primary alarm threshold range subsets and the number of the secondary alarm threshold range subsets are not limited in this embodiment.

It should be noted that, in this embodiment, the type of the movement degree threshold of the user attention object in the threshold range subset is not limited, and all thresholds that can reflect the factor of the movement degree of the object in the current picture may be used as the movement degree threshold in the threshold range subset related in this embodiment of the present application.

Optionally, the collecting device may match all information of the movement attribute information with a preset threshold range set to obtain a corresponding matching result.

S103, determining the recording information and the sending time of the current warning video according to the matching result, the type of the last warning video and the recording starting time of the last warning video.

Specifically, based on the matching result, the acquisition device may obtain the attribute of the current picture, for example, may obtain whether the current picture is a primary alarm picture or a secondary alarm picture. Optionally, when the current picture is the main alarm picture, the collecting device may determine the recording information and the sending time of the current alarm video according to the type of the last alarm video and the recording start time of the last alarm video, for example, if the last alarm video is the main alarm video, the time interval between the main alarm video sent to the server next time and the last main alarm should meet the main alarm interval. Therefore, when the current picture is the main alarm picture, whether the current time meets the main alarm interval from the recording start time of the last alarm video or not needs to be judged, if so, the acquisition equipment determines that the start recording time of the current alarm video is the time of the current picture, the acquisition equipment can start to acquire the main alarm video from the current time, and after the main alarm video with a certain time length is acquired, the main alarm video can be sent to the client equipment through the server.

Therefore, when the current picture is the secondary alarm picture, whether the current time meets the secondary alarm interval from the recording start time of the last alarm video or not needs to be judged, if so, the acquisition equipment determines that the recording start time of the current alarm video is the time of the current picture, the acquisition equipment can start to acquire the secondary alarm video from the current time, and after the secondary alarm video with a certain time length is acquired, the secondary alarm video can be sent to the client equipment through the server.

As can be seen from the above description, the present embodiment determines the type of the captured current frame, and based on the type of the current frame and the settings of the main alert interval and the secondary alert interval, the capture device can use the main alert interval to push the main alert video to the server in one case, and can also use the secondary alert interval to push the secondary alert video to the server in another case, that is, the capture device can use different alert intervals according to different situations to push the corresponding alert video to the server, thereby greatly avoiding the problem of frequently pushing the video to the client due to too short set time of the alert interval, and further avoiding the occurrence of missing an important scene due to too long set time of the alert interval, so that the present embodiment greatly improves the pushing effect of the alert video, and makes the human-computer interaction more intelligent, the experience effect of the user is improved.

According to the mobile detection alarm method provided by the embodiment of the invention, the acquisition equipment matches the mobile attribute information of the current picture with the preset threshold range set to obtain different matching results, and further determines the recording information and the sending time of the current alarm video according to the different matching results, the type of the last alarm video and the recording starting time of the last alarm video. Because the main alarm interval in the sub-set of the main alarm threshold range is larger than the secondary alarm interval in the sub-set of the secondary alarm threshold range in the embodiment of the invention, the acquisition equipment can push the main alarm video to the server by adopting the main alarm interval in one case and can also push the secondary alarm video to the server by adopting the secondary alarm interval in the other case according to different matching results. That is to say, the acquisition equipment can adopt different warning intervals according to the circumstances of difference, to the corresponding video of reporting an emergency and asking for help or increased vigilance of server propelling movement to the frequent video problem of customer end propelling movement that leads to of interval setting time of reporting an emergency and asking for help or increased vigilance greatly, in addition, has also avoided the interval setting of reporting an emergency and asking for help or increased vigilance the condition of missing important scene too long to take place, consequently, this embodiment has improved the propelling movement effect of the video of reporting an emergency and asking for help or increased vigilance greatly, and make human-.

Fig. 3 is a flowchart illustrating a motion detection alarm method according to an embodiment. The embodiment relates to an optional process of matching the acquisition device with a preset threshold range set according to the movement attribute information of the current picture to obtain a matching result. On the basis of the above embodiment, as shown in fig. 3, the above S102 may include the following steps:

s201: and if the movement attribute information is matched with the main alarm threshold range subset, determining that the current picture is a main alarm picture.

Specifically, the acquisition device matches the acquired movement attribute information of the current picture with a main alarm threshold range subset in a preset threshold range set, and optionally, when all information of the movement attribute information conforms to the main alarm threshold range subset, the movement attribute information is considered to be matched with the main alarm threshold range subset, and the current picture is determined to be the main alarm picture. Optionally, when part of the information of the mobile attribute information conforms to the subset of the main alarm threshold range, the mobile attribute information is considered to be matched with the subset of the main alarm threshold range, and the current picture is determined to be the main alarm picture. Optionally, when all the information of the mobility attribute information does not conform to the primary alarm threshold range subset, the mobility attribute information is considered to be not matched with the primary alarm threshold range subset. Optionally, when part of the information of the mobile attribute information does not conform to the subset of the primary alarm threshold range, the mobile attribute information is considered not to match the subset of the primary alarm threshold range. The embodiment is not limited to the specific matching method.

S202: and if the mobile attribute information is not matched with the primary alarm threshold range subset, judging whether the mobile attribute information is matched with the secondary alarm threshold range subset.

Specifically, when the mobile attribute information is not matched with the primary alarm threshold range subset, it is further determined whether the mobile attribute information is matched with a secondary alarm threshold range subset in the preset threshold range set.

Optionally, when all the information of the mobility attribute information conforms to the secondary alarm threshold range subset, the mobility attribute information is considered to be matched with the secondary alarm threshold range subset. Optionally, when part of the information of the mobility attribute information conforms to the secondary alarm threshold range subset, the mobility attribute information is considered to be matched with the secondary alarm threshold range subset. Optionally, when all the information of the mobility attribute information does not conform to the secondary alarm threshold range subset, the mobility attribute information is considered to be not matched with the secondary alarm threshold range subset. Optionally, when part of the information of the mobility attribute information does not conform to the secondary alarm threshold range subset, the mobility attribute information is considered to be not matched with the secondary alarm threshold range subset. The embodiment is not limited to the specific matching method.

S203: and if the movement attribute information is matched with the secondary alarm threshold range subset, determining that the current picture is a secondary alarm picture.

Optionally, if the threshold range set includes multiple secondary alarm threshold range subsets, when the motion attribute information matches any one of the multiple secondary alarm threshold range subsets, it is determined that the current picture is a secondary alarm picture.

In the movement detection alarm method provided by the embodiment of the invention, when the movement attribute information of the current picture is matched with the subset of the main alarm threshold range, the acquisition equipment determines that the current picture is the main alarm picture; when the mobile attribute information is not matched with the primary alarm threshold range subset, the acquisition equipment further judges whether the mobile attribute information is matched with the secondary alarm threshold range subset; and if so, determining that the current picture is the secondary alarm picture. Therefore, when the current picture is determined to be the main alarm picture or the secondary alarm picture, the method is a process of judging layer by layer, the accuracy of determining the type of the current picture is greatly improved, and the obtained matching result is more accurate. And then based on the accurate matching result, the process that the acquisition equipment determines the video to be pushed to the server at which alarm interval is more accurate, and the accuracy of video pushing is improved. In addition, the acquisition equipment can adopt different alarm intervals according to different conditions to push corresponding alarm videos to the server, so that the problem that the videos are frequently pushed to the client side due to the fact that the alarm interval setting time is too short is greatly avoided, and the situation that important scenes are missed due to too long alarm intervals is also avoided.

Fig. 4 is a flowchart illustrating a motion detection alarm method according to an embodiment. The embodiment relates to an optional process of determining the recording information and the sending time of the warning video according to the matching result of the movement attribute information of the current picture and a preset threshold range set, the type of the last warning video and the recording starting time of the last warning video by the acquisition equipment. On the basis of the above embodiment, as shown in fig. 4, the above S103 may include the following steps:

s301: and determining the adopted target alarm interval according to the type of the last alarm video.

Optionally, the type of the last warning video may be a primary warning video or a secondary warning video.

Optionally, if the last alarm video is the main alarm video, determining that the target alarm interval is the main alarm interval; and if the last alarm video is the secondary alarm video, determining the target alarm interval as the secondary alarm interval.

Optionally, the acquisition device may determine the type of the last warning video according to a status flag bit returned by the last warning video sent. Optionally, if the status flag bit is 2, it is determined that the last warning video is the primary warning video, and if the status flag bit is 1, it is determined that the last warning video is the secondary warning video. The embodiment does not limit the concrete way of how the acquisition device judges the type of the last warning video, and also does not limit the numerical value of the status flag bit.

Optionally, the primary alarm interval may be 20 minutes, and the secondary alarm interval may be 3 minutes, which is not limited in this embodiment.

S302: and judging whether the interval between the moment of the current picture and the recording starting moment of the last warning video is not less than the target warning interval or not to obtain a judgment result.

Specifically, the acquisition equipment calculates the interval between the moment of the current picture and the recording starting moment of the last alarm video, and when the interval is smaller than the target alarm interval, the alarm video does not need to be recorded; and when the interval is not less than the target alarm interval, recording the alarm video.

S303: and determining the recording information and the sending time of the current warning video according to the matching result and the judgment result.

Specifically, for different matching results and different judgment results, the recording information and the sending time of the alarm video determined by the acquisition equipment are different, and in one case, the acquisition equipment can push the alarm video at a main alarm interval and can record the main alarm video by adopting the recording time length a 1; in another case, the acquisition device may also use the secondary alarm interval to perform pushing, and may also use the duration a2 to record the secondary alarm video. No matter how the matching result is specifically combined with the judgment result, the acquisition equipment corresponds to a corresponding processing mode. An alternative implementation can be seen in the following description:

optionally, if the current picture is a main alarm picture and the interval between the time of the current picture and the recording start time of the last alarm video is not less than the target alarm interval, the main alarm video is recorded from the time of the current picture according to a first preset recording duration and sent to the client device through the server.

Optionally, the recording the main alarm video from the moment of the current picture according to a first preset recording duration includes: determining the time length required for acquiring the movement attribute information of the current picture; and synthesizing the recorded video corresponding to the time length in the cache and the video recorded from the moment of the current picture according to the first preset recording time length into the main alarm video. Because a certain time is needed for obtaining the movement attribute information of the current picture, and the movement scene may be continued all the time in the time, in the embodiment, the video in the time and the video recorded from the moment of the current picture are synthesized into the current main alarm video, so that the current main alarm video can include the whole alarm activity process as much as possible, the integrity of the alarm video is improved, and the alarm video is more accurate.

Optionally, if the current picture is a secondary alarm picture and the interval between the time of the current picture and the recording start time of the last alarm video is not less than the target alarm interval, the current alarm video is recorded from the time of the current picture according to a second preset recording duration and sent to the client device through the server.

Optionally, the recording the current warning video from the moment of the current picture according to the second preset recording duration includes: determining the time length required for acquiring the movement attribute information of the current picture; and synthesizing the recorded video corresponding to the time length in the cache and the video recorded from the moment of the current picture according to a second preset recording time length into the warning video of the time. Because a certain time is needed for obtaining the movement attribute information of the current picture, and the movement scene may be continued all the time in the time, in the embodiment, the video in the time and the video recorded from the moment of the current picture are synthesized into the current warning video, so that the whole warning activity process can be included in the current warning video as much as possible, the integrity of the warning video is improved, and the warning video is more accurate. Optionally, the first preset recording time may be 10 seconds, and the second preset recording time may be 5 seconds; optionally, the first preset recording time may be 15 seconds, the second preset recording time may be 10 seconds, and the specific values of the first preset recording time and the second preset recording time are not limited in this embodiment.

Optionally, if the current screen is the secondary alarm screen, before sending the secondary alarm screen to the client device via the server, the method further includes: if the last alarm video is the main alarm video, judging whether the last alarm video is successfully sent to the client equipment; if yes, carrying the secondary alarm video identification in the current alarm video; if not, the main alarm video identification is carried in the current alarm video. Optionally, if it is not known whether the last warning video is successfully sent to the client device, the warning video of this time is discarded. Optionally, a sending state returned according to the last warning video may be obtained, and then whether the last warning video is sent successfully is determined according to the sending state, and if the sending state value is 1, the sending is successful; if the transmission status value is 0, it indicates that transmission has failed. The embodiment does not limit the specific manner how the acquisition device determines whether the last warning video is successfully sent. In this embodiment, before sending the current-time warning video, it is determined whether the last-time main warning video was successfully sent to the client device, and when the last-time main warning video was successfully sent to the client device, the current-time warning video is identified as the secondary warning video; and under the condition that the network environment is poor, the last main alarm video is failed to be sent, so that the client equipment cannot receive the main alarm video for a long time, the user experience effect is poor, the current alarm video identification is changed into the main alarm video identification, the situation that the client equipment cannot receive the main alarm video for a long time under the poor network environment is avoided, and the user experience effect is improved.

In the mobile detection alarm method provided by the embodiment of the invention, on one hand, the acquisition equipment determines the adopted target alarm interval according to the type of the last alarm video, and on one hand, when the last alarm video is the main alarm video, the target alarm interval is determined to be the main alarm interval; under the other condition, when the last alarm video is the secondary alarm video, determining the target alarm interval as the secondary alarm interval; the acquisition equipment further judges whether the interval between the moment of the current picture and the recording starting moment of the last warning video is not less than the target warning interval according to the different target warning intervals to obtain a judgment result; the acquisition equipment further determines the recording information and the sending time of the warning video according to the matching result and the judgment result. Therefore, the acquisition equipment can adopt different alarm intervals according to different conditions to push corresponding alarm videos to the server, so that the problem that the videos are frequently pushed to a client side due to the fact that the alarm interval setting time is too short is greatly avoided, in addition, the situation that important scenes are missed due to too long alarm intervals is also avoided, the pushing effect of the alarm videos is greatly improved, man-machine interaction is more intelligent, and the experience effect of a user is improved. On the other hand, when the current picture is a main alarm picture and the interval between the moment of the current picture and the recording starting moment of the last alarm video is not less than the target alarm interval, the main alarm video is recorded from the moment of the current picture according to a first preset recording duration and is sent to the client equipment through the server; when the current picture is the secondary alarm picture and the interval between the moment of the current picture and the recording starting moment of the last alarm video is not smaller than the target alarm interval, the current alarm video is recorded from the moment of the current picture according to a second preset recording duration and is sent to the client equipment through the server. Therefore, under different conditions, the acquisition equipment adopts different recording durations when recording the warning video, the problem that the recording duration of the warning video is too short or too long is avoided, the problem that warning information is not comprehensive enough or redundant information is too much is avoided, the pushing effect of the warning information is improved, man-machine interaction is more intelligent, and the experience effect of a user is improved. On the other hand, when the current picture is the main alarm picture, the acquisition equipment combines the recorded video corresponding to the time length in the cache and the video recorded from the moment of the current picture according to the first preset recording time length into the main alarm video of the time by determining the time length required for acquiring the movement attribute information; when the current picture is the secondary alarm picture, the acquisition equipment determines the time length required for acquiring the movement attribute information, and then combines the recorded video corresponding to the time length in the cache and the video recorded from the moment of the current picture according to the second preset recording time length into the current alarm video. It can be seen that, because it takes a certain time to obtain the movement attribute information of the current picture, the movement scene may be continued all the time in this time, the acquisition device synthesizes the video in this time and the video recorded from the moment of the current picture into the present warning video, so that the present warning video can include the whole warning activity process as much as possible, the integrity of the warning video is improved, the warning video is more accurate, based on the more accurate warning video, the pushing effect of the warning video is further improved, the man-machine interaction is more intelligent, and the experience effect of the user is improved. On the other hand, when the current picture is the secondary alarm picture and the last alarm video is the main alarm video, the acquisition equipment firstly judges whether the last alarm video is successfully sent to the client equipment; if yes, carrying the secondary alarm video identification in the current alarm video; if not, the main alarm video identification is carried in the current alarm video. It can be seen that, when the acquisition device sends the current warning video, the acquisition device performs different processing on the identifier of the current warning video by combining the sending condition of the last warning video. When the poor network environment causes the sending failure of the primary alarm video at the last time, the client equipment cannot receive the primary alarm video for a long time, the user experience effect is poor, at the moment, the acquisition equipment changes the primary alarm video identification into the primary alarm video identification, so that the user can receive the primary alarm video, the situation that the client equipment cannot receive the primary alarm video for a long time under the poor network environment is avoided, the man-machine interaction is more intelligent, and the experience effect of the user is improved. In the process of determining the recording information and the sending time of the current warning video, the collecting device needs to combine different warning types of the current picture, different types of the last warning video, the recording starting time of the last warning video, and the sending state of the last warning video, so as to determine whether to record the current warning video, the recording duration of the current warning video, whether to send the current warning video, what kind of warning identifier should be carried when sending the current warning video, and the like. The process is a process combining current alarm video information and historical alarm video information and is also a process of step refining and advancing, so that a user client can receive sufficient alarm video, frequent pushing of redundant information is avoided, the pushing effect of the alarm video is improved, the intelligence of man-machine interaction is improved, and the user experience effect is improved.

Considering the network environment, the acquisition device hopes that the smaller the code flow rate generated by the video coding, the better, but the better the reduced code flow will cause the video quality to be degraded, so we introduce the method as shown in the following embodiment to improve the quality of the corresponding alarm video and reduce the pressure of the transmission bandwidth.

In one embodiment, the subset of threshold ranges further comprises: a maximum coderate limit, a coderate switching period, a coderate change step value, and a number of changes. Therefore, on the basis of the above embodiment, the method further includes:

Optionally, the maximum bitrate limit, the bitrate switching period, the bitrate change step value, the number of times of change, and other factors may be fixed values, optionally, the maximum bitrate limit may be 1.8Mbps, the bitrate switching period may be 30 seconds, the bitrate change step value may be 0.3Mbps, and the number of times of change may be 3. The present embodiment does not limit the specific values of the maximum bitrate limit, the bitrate switching period, the step value of the bitrate change, and the number of changes.

Alternatively, the maximum bitrate limit, the bitrate switching period, and the bitrate change step value may be dynamically changed according to the number of changes, and the current number of reductions. This embodiment is not limited to this.

In the mobile detection alarm method provided by the embodiment of the invention, when the acquisition equipment sends the alarm video, the code flow rate is adjusted according to the alarm type, and when the alarm type is the main alarm, the code flow rate is increased to the maximum code flow rate limit value, so that the transmission quality of the main alarm video concerned by a user is ensured, and then the transmission quality is gradually reduced along with the time, thereby reducing the transmission pressure of the bandwidth and further improving the utilization rate of the bandwidth.

In order to make the warning video more fit with the object concerned by the user, the acquisition device further provides a method for receiving a threshold range set issued by the server at irregular intervals in the following embodiment.

In one embodiment. The acquisition equipment receives a threshold range set which is sent by the server in an irregular mode. On the basis of the above embodiment, the method further includes:

Specifically, since the mobile scene that the user pays attention to irregularly changes, the server changes the threshold range set irregularly according to different needs of the user, sends the threshold range set to the acquisition device irregularly, and after the acquisition device receives the threshold range set sent by the server, the preset threshold range set is changed into a new threshold range set sent by the server, and the mobile attribute information of the current picture is matched with the new threshold range set sent by the server. Therefore, the alarm information sent to the client equipment better conforms to the content concerned by the user, and the effectiveness of the alarm information sent to the user client and the intelligence of man-machine interaction are greatly improved.

For the warning video, the video information provided by the cloud storage is more comprehensive, and the acquisition equipment can send the video information to the cloud server. According to the influence of bandwidth, and in combination with the h264 coding characteristic of one of the video coding and decoding technical standards, the acquisition device provides a method for selectively dropping frames as shown in the following embodiments.

In one embodiment, the acquisition device uploads I frame data of a current frame to a cloud server if an object in the current frame is in a non-moving state. On the basis of the above embodiment, the method further includes:

Specifically, when an object in the current picture is in a moving state, the acquisition equipment uploads all the full-frame data of the current picture to the cloud server; and when the object in the current picture is in a non-moving state, the acquisition equipment uploads the I frame data of the current picture to the cloud server. By the selective frame loss mode, the video sufficiency of the mobile scene concerned by the user is ensured, the transmission pressure is effectively reduced, and the bandwidth utilization rate is improved.
