Problems solved by technology

[0004] However, the existing tracking control system has a large-scale change of the tracking target (such as a certain vehicle, the distance between the vehicle and the spherical camera will change in a large scale when the vehicle is driving towards and away from the spherical camera. change) and background clutter are not robust, resulting in low control accuracy of the spherical camera

Embodiment Construction

[0068] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0069] The embodiment of the present invention discloses a tracking control method and a tracking control system, so as to realize the precise control of the rotation angle and focus of the spherical camera, enhance the tracking performance of the target to be tracked, and ensure that the target to be tracked is always in the spherical camera with a fixed size. In the middle of the field of view.

Abstract

The invention discloses a tracking control method and a tracking control system. According to the invention, a target with the highest matching degree with feature information of a tracking target in a current video frame image is taken as a target to be tracked, the position deviation of a central position of the target to be tracked relative to a central position of the current video frame image in real time and a proportional change rate of the area occupied by the region area of the target to be tracked in the current frame image are calculated in real time, a PID control algorithm is adopted for the position deviation and the proportional change rate, and accurate control for the rotation angle and focusing of a spherical camera is realized, so that the target to be tracked is ensured to stay at the middle of the view field of the spherical camera in a fixed size, and the tracking performance for the target to be tracked is enhanced.

Description

technical field [0001] The invention relates to the technical field of intelligent video monitoring, and more specifically, relates to a tracking control method and a tracking control system. Background technique [0002] Traditional video surveillance systems often require long-term manual observation by monitoring personnel, and then the monitoring personnel intervene on abnormal events in the surveillance video according to their subjective consciousness. Since it is impossible for monitoring personnel to be in a highly concentrated state for a long time, the scope of use of this kind of video surveillance system is limited. [0003] With the development of the economy, the use of video surveillance systems continues to increase, and the traditional video surveillance system can no longer meet the needs. Under this background, the tracking control system came into being. The tracking control system generally uses a spherical camera to achieve monitoring tasks, which has ...
