摘　　要：设计一种基于DSP-TMS320VC5416与FPGA的实时图像跟踪系统.该系统首先采用FPGA实现对图像数据的3×3中值滤波,滤波后数据采用乒乓操作的方式传输给DSP处理器.在跟踪算法上采用了直方图作为目标特征,使用直方图后向投影方法实现对动态目标的跟踪.采用浮点数定点化处理,提高了算法的运行速度.实际结果应用表明:该系统具有良好的实时性与稳定性.Based on TI DSP-TMS320C5416 and FPGA, a new system for tracking of target on Histogram back-projection is presented. The original data are firstly filtered using median filter with 33 windows, then, transmitted to DSP by Ping-Pang Method. The histogram is selected as the object characteristic, and is compared with histogram back-projection for object tracking. The fixed pointer operation is used for fast computing velocity, instead of the floating pointer operation. The result of some experiments has shown ...
