The Research On Target Detection And Tracking In IR Alarm System

IR moving target detection and tracking under complex environment is a key problem in IR alarm system. A lot of low altitude objects and the characteristics of point target make the detection and tracking even harder. Now there are many detection algorithms, such as nerve-network training, wavelet transform. However these algorithms couldn't reach real-time request. Tracking algorithms include centroid tracking and correlative tracking etc. Different tracking algorithms are adapted in different process for ensuring steady effect. Moreover, the solution to sheltered target is required to be considered.The paper mainly researches the weak point moving target detection and tracking technology in the infrared image, introduced the domestic and foreign research dynamic and obtain achievement. Proposed the integration algorithm of the detection and tracking for the weak point moving target in sequence images elaborated in detail the key technologies of the goal detection and tracking and has carried on the massive theory and experiment analyzes. And utilizes based on the wavelet territory multi-layered block match movement estimated the algorithm has done the massive analysis research work to the multi-objective track algorithm.
