摘　　要：为了提高系统的实时性,提出了基于高速数字信号处理器TMS320VC5410DSP的图像识别跟踪系统,并给出了成像跟踪的原理图和结构框图,重点论述了波门电路的设计。整个系统由视频采集模块、图像处理模块、实时显示模块、伺服机构等模块组成。还对系统中图像预处理、图像分割、特征提取目标识别、目标跟踪等采用的算法进行了阐述,最后通过实验进行仿真并给出仿真结果图,实验结果与理论相符,表明本系统是可行和有效的.In order to enhance the real_time traits, based on the DSP(TMS320VC5410), a real_time image recognizing and tracking system consisting of four modules is introduced in this paper. The algorithm includes image pre_processing, image segmentation, selecting feature and target tracking, which are explained in turn. At the same time, block diagrams of image tracking are given. Finally, the method is emulated with a computer, and the experimental results are found in accordance with theoretical ones,showing that the system is feasible and effective.
