摘　　要：主要对创新实验室二维视觉跟踪转台的算法进行改进。传统的算法只能实现在白色背景下对黑色目标的识别与跟踪,为实现对不同目标复杂背景的跟踪,针对跟踪系统设备和系统指标要求,确定了图像预处理、图像分割、形心跟踪等算法。针对目标的特点,根据识别的目标用形心跟踪算法进行跟踪。文中所有控制程序都基于LabVIEW,在MFC框架下用C++编写图像处理程序。结果表明,在LabVIEW平台下的识别跟踪过程中,二维转台最终实现良好的控制,使整个系统快速、准确的跟踪运动的特征物体,完成了二维目标视觉检测与跟踪的目的。For realizing the tracking of different targets in complicated background, the algorithm such as im- age 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-dimension- al 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.
