Embodiment Construction

[0031] When using the monitoring system for target tracking, although the smart camera can realize the positioning and tracking of the target object, due to the high requirements for the recognition pixels, the field of view of the smart camera is generally small. When the target object leaves the field of view of the smart camera, it is very difficult It is difficult to determine which camera's field of view the target is currently in, and it is easy to lose track of it. The camera with a large field of view is generally a non-smart camera due to the limitation of the target pixels. The feature of the large field of view of the non-smart camera can be used to realize the search of the target object. However, non-intelligent cameras cannot realize the function of automatic target tracking, and due to cost constraints and a large demand for monitoring equipment in the entire monitoring system, it is inevitable to use non-intelligent cameras. Moreover, if each smart camera needs...

Abstract

The embodiment of the invention provides a dynamic tracking control method and device and control equipment, and the method comprises the steps of converting the relative position, obtained by an intelligent camera, of a target object into absolute position information through an established coordinate conversion model, and obtaining a tracking camera of which the longitude and latitude range corresponding to a visual angle comprises the absolute position; converting the absolute position information of the target object into relative position information relative to the tracking camera according to the coordinate conversion model, and controlling equipment parameter change to enable the target object to be kept in the middle position of a shot picture of the tracking camera, thereby realizing positioning tracking of the tracking camera on the target object. According to the dynamic tracking control scheme, the linkage function of other cameras in the system is realized by means of theidentification information of the intelligent camera for the target object and in combination with the established coordinate conversion model. The defects that in the prior art, background equipmentis needed for video analysis and processing, so that the processing amount is large, and tracking lags behind are overcome.

Description

technical field [0001] The present application relates to the technical field of video surveillance, in particular, to a dynamic tracking control method, device and control equipment. Background technique [0002] When using a monitoring system for target tracking, although non-intelligent cameras have the characteristics of far vision, large scenes, etc., and a large field of view, non-intelligent cameras cannot realize the function of automatic target tracking. In order to improve the problem that the non-smart camera cannot track the target object, the background equipment is generally used to analyze and process the video collected by the non-smart camera, so as to detect the target object, and then control the non-smart camera to track the target object. This method requires the background device to analyze and process the video stream, which requires a large amount of processing and lags behind the tracking. In addition, although the smart camera can realize the dynam...
