摘　　要：提出了基于高速数字信号处理器TMS320C6415的图像识别跟踪系统,并给出了成像跟踪系统的原理图和结构图,重点论述了采集系统和图像处理系统。在软件上采用矩不变阈值分割和基于梯度的自适应阈值分割提取目标,采用投影特征的质心跟踪算法及基于线性微分拟合的记忆外推跟踪技术跟踪目标。实验结果表明:该系统跟踪稳定可靠,完全满足实时性要求。The real-time image tracking system based on the DSP (TMS320C6415) for moving targets using charge coupled plane array imaging device (CCD) is discussed.The principle diagram and block diagram is given,and the image acquisition and image processing system are discribed.The moment-preserving thresholding method and the adaptive thresholding method based on gradient are used to pick up targets, and the mass centroid tracking algorithm based on orthogonal projection and linear-fitting predicting approach are used to track targets. The experimental results show that the algorithm is feasible and practical.
