For realizing the tracking of different targets in complicated background, the algorithm such as image preprocessing, image segmentation, centroid tracking are confirmed according to the requirements of tracking system equipment and system characteristic. According to the characteristics of targets and the identified targets, centroid tracking algorithm is used for tracking. All the control programs are based on LabVIEW and C++ is used to write image processing program under MFC frame. Results show that good control can be realized by two-dimensional turret finally during identification and tracking process under LabVIEW platform. The whole system can track the moving feature object quickly and accurately. And two-dimensional visual target detection and tracking purpose can be completed.
