Problems solved by technology

[0004] However, limited by the visual range of the video camera, the screen range is also limited. When the moving target is viewed passing through the screen, if the moving target leaves the current screen range, it cannot continue to track. It must be based on the current moving direction of the moving object. Combine the map to find the video camera closest to the video camera of the current line, obtain the recorded picture, and then click to play to realize further tracking of the moving target
[0005] This kind of search often wastes a lot of time, and it is impossible to grasp the movement of the moving target in real time, cannot form an effective relay based on the video picture, and cannot guarantee the continuity of the video picture of the moving target acquired

Embodiment 1

[0060] Embodiment 1 of the present invention provides a video screen relay playback method, the process of which is as follows figure 1 shown, including the following steps:

[0061]Before executing the following process, first establish a three-dimensional coordinate system, collect picture data within the 360-degree field of view of the first video device at the reference position, establish a three-dimensional coordinate system with the first video device as the center of the circle, and divide the video picture into grids, And the content of the video picture is extracted, and the object elements in the video picture are converted into points in the three-dimensional coordinate system.

[0062] Step S101: Obtain video frame data when the first video device rotates.

[0063] When the video device rotates, the video picture changes, and the changed video picture data is acquired according to the set acquisition rules. For example, it is acquired according to a set cycle, o...

Embodiment 2

[0086] Embodiment 2 of the present invention provides a specific implementation process of the video screen relay playback method, and its implementation process is as follows Figure 4 As shown, a specific system structure example such as Figure 5 As shown, the method includes the following steps:

[0087] Step S401: Automatically collect panoramic video image data within a 360-degree field of view of the first video device by using a designated pan-tilt control protocol.

[0088] For example: Automatically collect the picture data within the 360-degree field of view of the camera and the camera.

[0089] Such as Figure 5 The shown video screen relay playback system includes a client, a video access platform, a camera A, a camera B, a picture extraction and a three-dimensional modeling module, wherein the camera A is used as the first video device, and the camera B is used as the second video device. example.

[0090] On the basis of accessing the video stream of the fr...

Abstract

The invention discloses a video image relay playing method, system and device. The video image relay playing method comprises the steps of acquiring video image data in rotation of first video equipment; positioning and recognizing an object appeared in the video image data according to an azimuth angle of the rotation and a pre-established three-dimensional coordinate system, wherein the three-dimensional coordinate system is established in a mode of collecting image data of the first video equipment within a field-of-view range of 360 degrees at a reference position and taking the first video equipment as a center; and when a concerned target object is judged to appear in the video images, acquiring and playing video images of second video equipment within a specified range around the concerned target object. According to the invention, relay playing of the video images can be realized quickly and effectively, so that the continuity and non-interruption of the video images are ensured, and the target object is effectively tracked.

Description

technical field [0001] The invention relates to the technical field of network video, in particular to a method, system and device for relay playing of video images. Background technique [0002] With the development of network and video technology, the application of video equipment in the road network system is becoming more and more extensive. Many cities are building a public security skynet system in safe cities, and a large number of video equipment have been built on urban roads and main streets. It is used to check the dynamics of the road surface. [0003] For example, at present, a large number of video cameras are built on the main streets of the city, including a large number of speed dome equipment. The current dome equipment can check the real-time dynamics of the road surface, and the second can realize the regular polling function by setting the preset position, so that To a certain extent, view the moving picture of the moving target. [0004] However, lim...
