Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. 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.
Fig. 1 schematically shows a system architecture to which the method for providing perimeter area monitoring according to the embodiment of the present invention is applied, where the system architecture may be applied to a ring area, and the system architecture may include a plurality of cameras 101, a monitoring storage device 102, and a client 103, which are connected through a data line or a network. The plurality of cameras 101 face the monitoring area, which is inside the border, i.e. all cameras 201 face inside the border.
The camera 101: are arranged on the border of the monitored area. The plurality of cameras 101 face a monitoring area (the monitoring direction is perpendicular to the extending direction of the monitoring area boundary) according to the same height and the same pitch angle, are numbered sequentially from a first camera 101 in a certain direction (clockwise or anticlockwise), and are connected end to form a closed loop from 1 to N. Each camera has a view field that is partially overlapping in direction with the view fields of its left and right neighbors, as shown in fig. 1.
Monitoring the storage device 102: establishing data connection with the camera 101 and the client 103, and storing audio and video information acquired by the camera 101; is responsible for receiving client 103 commands and providing video data to the client 103.
The client terminal 103: the monitoring video of the camera 101 can be obtained from the monitoring storage device 102, and is played and displayed on the playing interface.
As an optional solution, the embodiment of the present invention further provides another system architecture to which the method for monitoring a perimeter area is applied, where the system architecture may be applied to a ring area, and the system architecture may include a plurality of cameras 201, a monitoring storage device 202, and a client 203. As shown in fig. 2, the plurality of cameras 201 face the monitoring area, and the monitoring area is outside the boundary, that is, all the cameras 201 face the outside of the boundary.
As an alternative, the embodiment of the present invention further provides another system architecture to which the method for monitoring the perimeter area is applied, where the system architecture may be applied to a strip-shaped area, such as an expressway. The system architecture may include a plurality of cameras 301, a monitoring storage device 302, and a client 303, where the cameras 301 are arranged in the same direction, but not end-to-end to form a closed loop, as shown in fig. 3. Of course, two sets of cameras 301 in different directions may be disposed on two sides of the bar-shaped area, or other settings beneficial for acquiring the monitoring videos may be disposed.
Based on the above system architecture, fig. 4 exemplarily shows a flow of a method for monitoring a perimeter area, which can be performed by a device for monitoring a perimeter area according to an embodiment of the present invention.
In the system architecture, the monitoring directions of all the cameras are perpendicular to the extending direction of the boundary of the monitoring area, and the visual field ranges of the adjacent cameras are partially overlapped in the extending direction of the boundary of the monitoring area. After the tour direction is determined, the playing sequence of the videos shot by each camera on the playing interface is determined, and the following process is performed.
The first adjacent camera is a first camera which is located behind the current camera and determined according to the tour direction.
It should be noted that, the current camera and the first adjacent camera are two adjacent cameras, the monitoring directions of the two adjacent cameras are both toward the monitoring area, and the picture of the monitoring video of the current camera and the picture of the monitoring video of the first adjacent camera may have an overlapping picture or may not have an overlapping picture. The specific situation is as follows:
when the picture of the surveillance video of the current camera and the picture of the surveillance video of the first adjacent camera have overlapped pictures, as shown in fig. 5a, the thin solid line represents a picture 1, which is the picture shot by the current camera; the dashed line represents frame 2, which is the frame taken by the first adjacent camera; the bold solid line represents the video playing interface, that is, in fig. 5a, the current video playing interface plays the frame 1 and includes a part of the frame 2, that is, the overlapped frame of the two.
When the picture of the surveillance video of the current camera and the picture of the surveillance video of the first adjacent camera have no overlapping picture, as shown in fig. 5b, the thin solid line represents picture 1, which is the picture shot by the current camera; the dashed line represents frame 2, which is the frame taken by the first adjacent camera; the thick solid line represents the video playing interface, that is, in fig. 5b, only frame 1 is played in the current video playing interface.
Here, according to the overlapping situation of the picture of the monitoring video of the current camera and the picture of the monitoring video of the first adjacent camera, the switching manner can be divided into two cases:
the first condition is as follows: when the picture of the monitoring video of the current camera and the picture of the monitoring video of the first adjacent camera have overlapped pictures, the picture of the monitoring video of the current camera is cut according to a first preset speed, and the picture of the monitoring video of the first adjacent camera is displayed in a moving mode according to the first preset speed until all the monitoring videos of the first adjacent camera are displayed on the playing interface.
Case two: when the picture of the monitoring video of the current camera and the picture of the monitoring video of the first adjacent camera are not overlapped, the picture of the monitoring video of the current camera is cut according to a second preset speed, and the picture of the monitoring video of the first adjacent camera is displayed in a moving mode according to the second preset speed until all the monitoring videos of the first adjacent camera are displayed on the playing interface.
The first preset speed and the second preset speed may be set to be a horizontal preset speed or a vertical preset speed according to experience. When the first and second preset speeds are horizontal preset speeds, the following embodiments can be explained.
Here, the first preset speed is determined according to a picture width of the monitoring video of the current camera, a width of the overlapped picture, and a frame number of the monitoring video of the current camera. Further, the first preset speed is determined according to the difference value between the width of the monitoring video of the current camera and the width of the overlapped picture, and the frame number of the monitoring video of the current camera.
Illustratively, this may be as shown in equation (1).
The above formula (1) is:
V1＝ΔX1/N……………………(1)
wherein, V1Presetting the speed, Δ X, for the first level1The difference value of the width of the monitoring video of the current camera and the width of the overlapped picture is obtained; and N is the frame number of the monitoring video of the current camera, namely the frame generation number in the monitoring video of the current camera, and is determined according to the playing time of the monitoring video of the current camera.
The first horizontal preset speed determined according to the formula (1) can meet the requirement, when the playing of the monitoring video of the current camera is finished, the monitoring video of the first adjacent camera is just played on the playing interface, and the continuous splicing display of the monitoring videos of the two adjacent cameras is realized.
The second preset speed is determined according to the picture width of the monitoring video of the current camera and the frame number of the monitoring video of the current camera.
Illustratively, this may be as shown in equation (2).
The above formula (2) is:
V2＝ΔX2/N……………………(2)
wherein, V2Presetting the speed, Δ X, for the second level2The frame width of the monitoring video of the current camera is defined, and the N is the frame number of the monitoring video of the current camera, namely the frame generation number in the monitoring video of the current camera, and is determined according to the playing time of the monitoring video of the current camera.
The second horizontal preset speed determined according to the formula (2) can meet the requirement that when the playing of the monitoring video of the current camera is finished, the monitoring video of the first adjacent camera is just played on the playing interface, and the continuous splicing display of the monitoring videos of the two adjacent cameras is realized.
As an implementation manner, when the picture of the surveillance video of the current camera and the picture of the surveillance video of the first adjacent camera have overlapping pictures, refer to fig. 6a, where a thin solid line indicates a picture 1, which is a picture taken by the current camera; the dashed line represents frame 2, which is the frame taken by the first adjacent camera; the bold solid line represents the playing interface of the video, that is, in fig. 6a, the current playing interface of the video is frame 1 and includes a part of frame 2 (the overlapped frame of the two). The frame number of the monitoring video of the current camera is N, and the difference value between the width of the picture 1 and the width of the overlapped picture is Delta X1When the monitoring video of the current camera is played completely, the playing interface is switched from the picture 1 to the picture 2, and the speed V needs to be preset according to the first level1(V1＝ΔX1and/N) cutting a picture 1 of the monitoring video of the current camera, and pulling a picture 2 into a playing interface in the horizontal direction according to the overlapped pictures. For better understanding of the embodiment of the present invention, fig. 6b and 6c show that the frame of the surveillance video of the current camera on the playing interface is switched to the frame of the surveillance video of the first adjacent camera according to the first horizontal preset speed according to the overlapped frames.
In addition, the current camera and the first adjacent camera can be reasonably arranged to realize that the picture of the monitoring video of the current camera and the picture of the monitoring video of the first adjacent camera have no overlapping pictures, that is, when the two have no overlapping pictures, as shown in fig. 7a, a thin solid line represents a picture 1, which is a picture shot by the current camera; the dashed line represents frame 2, which is the frame taken by the first adjacent camera; the thick solid line represents the playing interface of the video, and the current playing interface of the video does not include the frame 2. Fig. 7b and 7c show that the picture of the monitoring video of the current camera on the playing interface is at the second horizontal preset speed V2(V2＝ΔX2and/N) switching to the picture of the monitoring video of the first adjacent camera.
It should be noted that the width of the screen in the above embodiments is understood as the width in the horizontal direction of the playing interface.
Of course, when the first preset speed and the second preset speed are vertical preset speeds, there are:
the first preset speed is determined according to the picture height of the monitoring video of the current camera, the height of the overlapped pictures and the frame number of the monitoring video of the current camera. And the second preset speed is determined according to the picture height of the monitoring video of the current camera and the frame number of the monitoring video of the current camera. The specific implementation manner may refer to the above embodiments, which are not described herein again.
The above embodiment explains the switching between the picture of the surveillance video of the current camera and the picture of the surveillance video of the first adjacent camera, that is, the surveillance video of the current camera is switched to the surveillance video of the first adjacent camera, so that the user can continuously watch the surveillance video of the current camera and the surveillance video of the first adjacent camera on one play interface. Optionally, after the picture of the surveillance video of the current camera on the playing interface is switched to the picture of the surveillance video of the first adjacent camera according to the preset speed, the surveillance video of the first adjacent camera may be determined as the surveillance video of the current camera, and the picture of the surveillance video of the current camera on the playing interface is continuously switched to the picture of the surveillance video of the first adjacent camera according to the preset speed until the stop instruction is received.
Specifically, it can be seen from Table 1 that the time period is 0 to T1The monitoring video of the current camera is a video segment 1, the monitoring video of the first adjacent camera is a video segment 2, and the monitoring video is in a time period of 0-T1Playing the video segment 1, gradually switching the picture of the video segment 1 in the playing interface to the picture of the video segment 2 according to a preset speed (a first preset speed or a second preset speed) while playing the video segment 1, and at T1The handover is completed at that time. In a time period T1～T2When the monitoring video of the current camera is a video segment 2, the monitoring video of the first adjacent camera is a video segment 3, and the time period T is1～T2Playing the video segment 2, and gradually switching the picture of the video segment 2 of the playing interface to the picture of the video segment 3 according to the preset speed while playing the video segment 2And at T2Switching is completed all the time; and so on.
When a plurality of cameras form a ring-shaped area as shown in fig. 1 or fig. 2, after the monitoring video (video segment n) of the last camera is played on the playing interface, the picture of the video segment n is gradually switched to the video segment 1 again (where n is the number of cameras in the ring-shaped area, n is greater than or equal to 3), and the monitoring video is displayed in the ring-shaped area at TnThe handover is completed at that time.
When the plurality of cameras form a linear region as shown in fig. 3, after the monitoring video (video segment n) of the last camera is played on the playing interface, the monitoring video is directly skipped back to the monitoring video of the first camera. Equivalently, directly jumping to the video segment 1 after playing the video segment n (wherein n is the number of cameras in a linear region, and n is more than or equal to 2).

In the above embodiment, if the currently played video is the video segment 2, the video segment 2 is understood as the surveillance video of the current camera, the video segment 3 is understood as the surveillance video of the first adjacent camera, and the video segment 2 is switched to the video segment 3 according to the first preset speed or the second preset speed, then the video segment 3 is understood as the surveillance video of the current camera, and the video segment 4 is understood as the surveillance video of the first adjacent camera, and by such a loop, the loop playing of the surveillance video of the cameras in the whole surveillance area is completed, or the playing is stopped after the stop instruction is received.

In the scheme, the number of the cameras can be at least three, splicing operation is carried out when the monitoring videos of the adjacent cameras are only displayed on the playing interface, the occupied splicing resources and the occupied display resources are unchanged all the time, unnecessary operation is reduced, the cameras are independent when the monitoring videos are shot and stored, and the complexity of coding and storing is reduced.
In order to better explain the embodiment of the present invention, the following describes the flow of the perimeter region monitoring method in a specific implementation scenario, as shown in fig. 8, specifically as follows:
and step 801, numbering the cameras in each group along the monitoring direction, and determining the relative position relation of the fields of vision of the adjacent cameras.
