Embodiment Construction
[0034] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.
[0035] A multi-view extension method and device based on edge information mining provided by this application is described by using a camera to track suspicious vehicles, that is, the tracking target is a suspicious vehicle, and of course the suspicious application can also track other vehicles or people, and other moving objects Wait. The general idea of this application is that the camera finds suspicious vehicles through target recognition, such as license plate recognition; adjusts the angle of the camera through target detection to track the target; when the target is about to go aw...

The invention discloses a multi-view-field extension method and device based on edge information mining. A first camera performs tracking shooting on the target, downloads a map containing position information of surrounding cameras in an area where the map is located; when the target is about to leave the view of the first camera, the first camera selects a second camera which continues to trackfrom surrounding cameras within the view range, sends feature information of the target and information of a video stream receiver to the second camera, and the second camera feeds back a source IP address and a port number for sending a video stream to the first camera; and the source IP address and the port number of the video stream sent by the second camera are sent to a video stream receiver,the video stream receiver is notified to prepare to receive the video stream sent by the second camera, and the second camera is notified to send the video stream to complete switching. The cameras are automatically switched, a central management server is not needed to intervene in coordination, and linkage replacement tracking work between the cameras is achieved.
Description
technical field [0001] The present application belongs to the technical field of video tracking, and in particular relates to a multi-view extension method and device based on edge information mining. Background technique [0002] Video surveillance is an important part of the security system. Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. In recent years, with the rapid development of computer, network, image processing and transmission technology, the popularization trend of video surveillance has become more and more obvious. In the urban video surveillance system, if a suspected target appears in the field of view of the surveillance screen, it needs to be tracked. The current technical solutions are generally tracked by switching images manually, or according to the predetermined route of the target, the management server makes a plan and designates multiple cameras to track and shoot. ...
