Target tracking method and device

Abstract

The invention discloses a target tracking method and device, belonging to the technical field of monitoring. The method includes: during the process of tracking the target in the video of the first camera, when the target crosses the trigger line in the video of the first camera, acquiring the trigger position on the trigger line, the trigger line refers to the main field of view of the first camera The boundary line between the area and the main field of view of the second camera, the trigger position refers to the position where the movement track of the target intersects the trigger line; based on the trigger position, the target is positioned in the video of the second camera; track the target in the video. The present invention locates the target in the video of the second camera based on the trigger position of the target on the trigger line, thereby automatically switching to the video of the second camera to continue tracking the target, without the need for the user to manually track the target in the video of the second camera Find the target to locate the target, greatly improving the efficiency of tracking the target.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a target tracking method and device. Background technique [0002] With the development of monitoring technology, people can set up cameras in various places such as vaults, art galleries, shopping malls, etc. The cameras can shoot in real time during operation, and the videos captured by the cameras can be used for target tracking, such as tracking a suspect, tracking A suspect vehicle, etc. [0003] In the process of target tracking, the user can roughly analyze the position where the target will appear, find out the camera installed at the position, and watch the video of the camera. When the target enters the field of view of the camera, the target will appear in the video. If the target is selected, the camera can determine the target selected by the user, and use the feature tracking algorithm to track the target in the video. Specifically, according to the image of th...
