Abstract

The invention discloses a moving object tracking method and device. The method comprises the steps of obtaining the current plane coordinate of the moving object in the current image; determining thecurrent plane speed corresponding to the current plane coordinate based on the corresponding relation between the preset plane coordinate and the plane speed; determining the current angle of visual field of a tracking camera; Based on the current plane speed and the current angle of visual field, the current rotation angle speed of the tracking camera can be determined, and the tracking camera tracks the moving target based on the current rotation angle speed. The invention is advantageous in that the mobility of the moving target in the plane picture can be improved.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a method and device for tracking a moving target. Background technique [0002] Moving target tracking is to use computer vision technology to process, analyze and understand video signals. Without human intervention, through automatic analysis of sequence images, it can locate, identify and track moving targets in the monitoring scene. On this basis, it analyzes and judges the behavior of the target, sends out an alarm or provides useful information in time when an abnormal situation occurs, effectively assists security personnel in dealing with crises, and minimizes false positives and missed negatives. [0003] At present, the tracking of the target often includes two stages, the first is the detection of the target, and the second is the tracking of the target. In order to realize the purpose of tracking the moving target, in the tracking method of the moving target, it is ne...
