Research On Target Tracking Technology Of Digital Monitoring System

With the development of science and technology, the level of automation improves continually, and human labor is being replaced by intelligent machine. Intelligent video survey is taking the place of human local survey. In recent years, video technology has developed rapidly, and been widely used in industry, national defense, commerce, traffic, finance, office automation and home security.This paper is mainly about motion detection and tracking technology of digital monitoring system, this paper mainly introduces three parts:motion detection, results analysis, and tracking. The objects detection section describes background subtraction technique;the analysis section uses the method of image morphology; the human motion tracking section discusses the use of combined algorithm to prevent Kalman filter from diverge, while to estimate the motion state of human in image sequence accurately.The algorithm of this paper is mainly using Matlab simulation, and the tracking results is relatively well.
