All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that, in this embodiment, the first and second video interfaces are only used for distinguishing the video interfaces, the first and second monitoring cameras are only used for distinguishing the monitoring cameras, and the first and second monitoring videos are only used for distinguishing the monitoring videos, and have no other meaning.
Specifically, in this embodiment, a picture-in-picture technology may be adopted to embed the first video interface in the second video interface, that is, the first video interface is a picture-in-picture interface of the second video interface. That is, the second video interface is a primary video interface, and the first video interface is a secondary video interface.
In this embodiment, the monitoring cameras include at least two or more than two, and may be arranged according to a specific target range to be monitored.
Fig. 1 is a flowchart of a first embodiment of a method for processing a surveillance video, as shown in fig. 1, the method of this embodiment may include:
step 101, acquiring a first monitoring video recorded by a first monitoring camera according to identification information of the first monitoring camera included in video switching information triggered by a first video interface;
for example, eight monitoring cameras are arranged in the present embodiment, each monitoring camera is arranged in a different area within the target range according to the target range to be monitored, and each monitoring camera monitors a different target area.
Each monitoring camera has its own identification information, for example, a hardware identification of the monitoring camera may be used as the identification information, coordinate position information of each monitoring camera in a target range may be used as the identification information, and for example, a serial number of each monitoring camera may be used as the identification information. In this embodiment, the video monitoring platform stores the identification information of each monitoring camera; meanwhile, the monitoring videos recorded by the monitoring cameras can be stored in the video monitoring platform, and the video monitoring platform can establish the corresponding relation between the identification information of the monitoring cameras and the corresponding monitoring videos.
In this embodiment, the video monitoring platform may display a first video interface and a second video interface, where the second video interface is a main video interface, and may display or play back a monitoring video recorded by one of the monitoring cameras in full screen real time, and the first video interface may display identification information of each of the monitoring cameras.
Assuming that a second video interface (main video interface) of the video monitoring platform currently plays a second monitoring video recorded by a second monitoring camera, a user can select the monitoring camera to be switched through identification information of each monitoring camera on the first video interface. Assuming that the user clicks the identification information of the first monitoring camera, the first monitoring video recorded by the first monitoring camera is acquired from the monitoring videos stored in the video monitoring platform according to the identification information of the first monitoring camera.
Step 102, interrupting a second monitoring video recorded by a second monitoring camera playing in a second video interface;
assuming that a second monitoring video recorded by a second monitoring camera is currently being played by a second video interface (main video interface), after a user clicks identification information of the monitoring camera in the first video interface to trigger video switching information, the second monitoring video recorded by the second monitoring camera being played in the second video interface needs to be interrupted, and an interrupted time point (interruption time) in the second monitoring video is obtained. Assuming that the second monitoring video is the played-back monitoring video, the interruption time point of the obtained played-back monitoring video, for example, the played-back monitoring video is the monitoring video from 8 am to 9 am yesterday, the interruption is divided at 8 o 'clock 30, and then 8 o' clock 30 yesterday is determined as the interruption time. Assuming that the second surveillance video is a currently real-time recorded surveillance video, the interruption time of the second surveillance video is the current time.
103, acquiring a surveillance video frame corresponding to the interruption time of the second surveillance video from the first surveillance video according to the interruption time of the second surveillance video;
that is to say, according to the interruption time of the second surveillance video, the interruption time of the second surveillance video is determined as the starting point time of the video to be played after switching, and according to the starting point time, the surveillance video frame corresponding to the starting point time is determined in the video to be played.
Corresponding to the example of the interruption time point in step 102, the played back monitoring video is the monitoring video from 8 am to 9 am yesterday, when interruption is performed at 8 am 30, 8 am 30 am yesterday is determined as interruption time, and 8 am 30 am yesterday is determined as the start time of the video to be played after switching, the video to be played determined in step 101 is the first monitoring video recorded by the first monitoring camera, in the obtained first monitoring video, the monitoring video frame corresponding to 8 am 30 am yesterday is searched, and the monitoring video frame corresponding to 8 am 30 am yesterday in the first monitoring video is used as the monitoring video frame of the playing start point.
If the second surveillance video is the currently real-time recorded surveillance video, the interruption time of the second surveillance video is the current time, that is, the current time is the starting time of the video to be played, and the currently recorded surveillance video of the first surveillance camera is directly switched to.
And 104, switching the interrupted monitoring video frame in the second monitoring video to the first monitoring video frame in the second video interface, and starting to play the first monitoring video from the first monitoring video frame.
Corresponding to the example in step 103, in the obtained first monitoring video, a monitoring video frame corresponding to 8 points per yesterday and 30 minutes is searched, after the monitoring video frame corresponding to 8 points per yesterday and 30 minutes in the first monitoring video is used as the monitoring video frame of the playing starting point, in the second video interface, the interrupted monitoring video frame in the second monitoring video is quickly switched to the monitoring video frame corresponding to 8 points per yesterday and 30 minutes in the first monitoring video, and the subsequent first monitoring video is played from the monitoring video frame corresponding to 8 points per yesterday and 30 minutes in the first monitoring video as the monitoring video frame of the playing starting point.
In the embodiment, a first video interface is embedded into a second video interface, identification information of each monitoring camera is displayed on the first video interface, video switching information is triggered by clicking a monitoring camera identification on the first video interface, a monitoring camera corresponding to the monitoring camera identification clicked on the first video interface is determined as a monitoring camera to be switched, a monitoring video recorded by the monitoring camera to be switched is obtained, a monitoring video which is being played on the second video interface is interrupted, a monitoring video frame corresponding to the interruption time is obtained from the monitoring video to be switched according to the interruption time of the interrupted monitoring video and is used as a monitoring video frame which is played at the beginning of the monitoring video to be switched, and the currently played monitoring video is switched to the monitoring video frame which is obtained from the monitoring video to be switched and corresponds to the interruption time in the second video interface, and playing subsequent monitoring videos in the monitoring videos to be switched from the monitoring video frame played at the beginning, and realizing the quick association of the monitoring videos recorded by different monitoring cameras to determine and continuously switch and play the monitoring videos. The method solves the problems that in the prior art, only one monitoring camera can be positioned at a time, and the monitoring video positioning, the display speed and the processing efficiency are low.
Further, in this embodiment, in the video monitoring platform, a direction corresponding relationship between the first monitoring camera and the second monitoring camera may also be established according to the position information of the first monitoring camera and the position information of the second monitoring camera. In the embodiment, firstly, the target range to be monitored is converted into an electronic map, and when the coordinate information of the monitoring camera is stored, the monitoring camera needs to be positioned in the electronic map, so that the positioning information of the monitoring camera is determined; and then, calculating the positioning information according to a preconfigured algorithm, so as to determine the coordinate information of the monitoring camera in the electronic map, and storing the coordinate information into a database of a video monitoring platform, so that the coordinate information of the monitoring camera in the electronic map is stored in each monitoring camera in the video monitoring platform contained in the electronic map. And then, according to the coordinate information of each monitoring camera in the electronic map, determining the position relationship among the monitoring cameras, further, determining the direction corresponding relationship among the monitoring cameras (namely the direction relation network of the monitoring cameras) according to the position relationship among the monitoring cameras, and displaying the direction corresponding relationship among the monitoring cameras on the first video interface.
For example, if a second surveillance video recorded by a second surveillance camera currently playing in the second video interface is assumed, and the first surveillance camera is located at the right side of the second surveillance camera, a right direction arrow is displayed in the first video interface, and a camera pointed by the right direction arrow is the first surveillance camera at the right side of the second surveillance camera; or the first monitoring camera is positioned on the left side of the second monitoring camera, a left direction arrow is displayed in the first video interface, and the camera pointed by the left direction arrow is the first monitoring camera on the left side of the second monitoring camera; or the first monitoring camera is positioned in front of the second monitoring camera, an upward direction arrow is displayed in the first video interface, and the camera pointed by the upward direction arrow is the first monitoring camera in front of the second monitoring camera; or the first monitoring camera is positioned behind the second monitoring camera, a downward arrow is displayed in the first video interface, and the camera pointed by the downward arrow is the first monitoring camera behind the second monitoring camera.
The directional relationship network of the monitoring cameras is not limited to the four directional relationships in the example, and may include eight directional relationships or sixteen directional relationships.
Fig. 2 is a flowchart of a second embodiment of a method for processing a surveillance video according to the present invention, and as shown in fig. 2, assuming that a second surveillance video recorded by a second surveillance camera that is currently playing in the second video interface, according to direction identification information included in video switching information triggered by the first video interface, a surveillance video recorded by a surveillance camera that is around the second surveillance camera and corresponds to the direction identification information is determined as a surveillance video to be switched. The specific implementation can include:
For example, when a user clicks a right direction arrow displayed on the first video interface on a second monitoring video recorded by a second monitoring camera being played in the second video interface, the monitoring video recorded by the monitoring camera pointed to by the second monitoring camera in the right direction is determined as the monitoring video to be switched. And if the first monitoring camera is positioned in the right direction of the second monitoring camera, taking the first monitoring video recorded by the first monitoring camera as the monitoring video to be switched.
And 203, determining the monitoring video frame which is played at the beginning in the monitoring video to be switched according to the interruption time of the second monitoring video.
For example, the second surveillance video is a surveillance video that has been recorded by the playback second surveillance camera, assuming that the second surveillance video is a surveillance video from 8 to 9 yesterday, assuming that the interruption time is 8 to 30 yesterday according to the interruption time of the second surveillance time, taking 8 to 30 yesterday as the start time of the surveillance video with switching, further assuming that the surveillance video to be switched is the first surveillance video, searching for a surveillance video frame corresponding to 8 to 30 yesterday in the first surveillance video, and determining the video frame as the surveillance video frame that is started to be played in the first surveillance video.
For example, in the first surveillance video, a surveillance video frame corresponding to 8: 30 points yesterday is searched, and the video frame is determined as a surveillance video frame which is played at the beginning in the first surveillance video, so that in the second video interface, a surveillance video frame interrupted by the second surveillance video is switched to a surveillance video frame which is played at the beginning in the first surveillance video, and the subsequent first surveillance video starts to be played.
In this embodiment, by establishing a directional relationship between the monitoring cameras and saving a method relationship between the monitoring cameras in the video monitoring platform, the directional relationship between the monitoring cameras is displayed on the first video interface, so that a user can determine, by clicking the displayed directional information on the first video interface, a monitoring video recorded by the monitoring camera corresponding to the directional information and around the monitoring camera corresponding to the monitoring video being played on the second video interface as a monitoring video to be switched, interrupt the monitoring video being played on the second video interface, obtain, according to the interruption time of the interrupted monitoring video, a monitoring video frame corresponding to the interruption time in the monitoring video to be switched, and use the monitoring video frame as the monitoring video frame to be initially played in the monitoring video to be switched, and in the second video interface, switch the currently played monitoring video to the monitoring video to be switched to obtain the monitoring video corresponding to the interruption time And frequency frame, namely playing the subsequent monitoring video in the monitoring video to be switched from the monitoring video frame played at the beginning, and realizing the quick association of the monitoring videos recorded by different monitoring cameras to determine and continuously switch and play the monitoring video. The method solves the problems that in the prior art, only one monitoring camera can be positioned at a time, and the monitoring video positioning, the display speed and the processing efficiency are low.
Further, in this embodiment, the orientation angles of the monitoring cameras are stored in the video monitoring platform, and the corresponding relationship between the orientation angles of the monitoring cameras is established according to the orientation angles of the monitoring cameras, and is displayed in the first video interface.
Fig. 3 is a flowchart of a third embodiment of a method for processing a surveillance video, where as shown in fig. 3, it is assumed that a second surveillance video recorded by a second surveillance camera is being played in the second video interface, and the method further includes:
And 303, operating the identification information of the first monitoring camera to acquire a first monitoring video recorded by the first monitoring camera.
And step 304, switching the second monitoring video to the first monitoring video.
During specific switching, for example, the second surveillance video may be interrupted, the interruption time is determined as the start-playing time of the first surveillance video according to the interruption time of the second surveillance video, a first surveillance video frame corresponding to the start-playing time is searched for at the first surveillance video according to the start-playing time, and a subsequent first surveillance video is played from the first surveillance video frame.
In this embodiment, by establishing the corresponding relationship of the orientation angles between the monitoring cameras and storing the corresponding relationship of the orientation angles between the monitoring cameras in the video monitoring platform, the orientation angle of the monitoring camera matched with the moving direction of the monitoring target is determined according to the moving direction of the monitoring target in the currently played monitoring video, and the identifier of the monitoring camera matched with the orientation angle is highlighted on the first video interface, so that a user can rapidly operate the identifier of the highlighted monitoring camera, obtain the monitoring video of the highlighted monitoring camera, and perform video switching. The rapid association of the monitoring videos recorded by different monitoring cameras is determined and the monitoring videos are continuously switched and played. The method solves the problems that in the prior art, only one monitoring camera can be positioned at a time, and the monitoring video positioning, the display speed and the processing efficiency are low.
