A Tracking Method of Target Location and Tracking System Based on Cctv Sensor Network

Abstract

The invention provides a tracking method for a target positioning and tracking system based on a CCTV sensor network. The target positioning and tracking system based on a CCTV sensor network includes an image acquisition terminal, an image preprocessing unit, a target detection unit, a working environment recognition unit, and a CCTV Sensor network node deployment unit, digital pan / tilt control execution unit, target space positioning unit, target space self-adaptive tracking unit and information output and display unit; the method of the invention detects the target through video image processing technology and obtains its position in the image The pixel coordinate position, combined with the installation latitude and longitude of the camera node in the CCTV sensor network, the height from the horizontal plane, and the camera’s direction angle and pitch angle provided by the digital pan / tilt control execution unit, according to the target detection unit and the CCTV sensor network node allocation unit Adaptively deploy the optimal cooperative node pair to align the target, and complete the 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...
