Abstract: In this paper, a double tracking algorithm target tracking system based on DM6437-355 development board combining with OpenCV and VC technology is designed. Both the centroid tracking algorithm and the center of gravity tracking algorithm are set into the system,the centroid tracking algorithm is an improvement based on threshold image segmentation pretreatment,the center of gravity tracking algorithm is proposed for setting different weights I(x,y) for each sample point, it is an improvement solving the coordinates of the center of gravity. The phenomenon has been significantly improved, that the tracked target is lost by the target rolling and deforming and partially being shaded. A different tracking algorithm depending on different situations is chosen,the target tracking results in the midst of a real environment is strengthened.
