Application of the template matching method in high speed target tracking

A fast identification algorithm for high speed target is presented. According to the characteristics of image target and background, a cross matching template is designed which distinguishes the target by the difference of grayness between the area to be identified and the cross matching template. Thus the traditional point by point scanning method is abandoned. In order to improve the speed of identification, target images are binary processed. Logic calculation is adopted to obtain the comparability estimate between the matching template and target. By comparing the comparability estimate and its threshold, the scanning points skip. The simulation results showed that this algorithm improves the identification speed greatly and realizes the control of shooting angle for the high speed vidicon, so as to track the target in real time.
