Abstract

The invention provides a tracking method of a target positioning and tracking system based on a CCTV sensor network. The CCTV sensor network-based target positioning and tracking system comprises an image acquisition terminal, an image preprocessing unit, a target detection unit, a working environment cognition unit, a CCTV sensor network node deployment unit, a digital holder control execution unit, a target space positioning unit, a target space self-adaptive tracking unit and an information output and display unit; according to the method, the target is detected through the video image processing technology, and the pixel coordinate position of the target in the image is obtained; information such as installation latitude and longitude of a camera node in a CCTV sensor network, a distance from the camera node to a horizontal plane, and a direction angle and a pitch angle of a camera provided by a digital holder control execution unit are combined; and according to the target detection unit and the CCTV sensor network node deployment unit, the optimal cooperative node pair isself-adaptively deployed to align with the target, so as to complete spatial position determination and continuous track tracking of the target.

Description

technical field [0001] The invention relates to a video monitoring system and the technical field of video monitoring and target continuous space positioning and tracking, in particular to a tracking method for a target positioning and tracking system based on a CCTV sensor network. Background technique [0002] The traditional video surveillance system collects image information through camera nodes and stores and plays back. It is difficult to spatially locate and track the targets appearing in the video. As a result, when an emergency accident occurs, the coordinate position of the accident point cannot be quickly determined. Facilitate quick response to incidents. With the rapid improvement of my country's economic development, the road traffic monitoring system and public security management monitoring system are facing increasing pressure, and they cannot effectively locate and track targets continuously when responding to emergencies. At the same time, the inland shi...
