摘　　要：研究高速并行互相关图像跟踪处理设计技术 ,解决复杂背景下低对比度目标的跟踪问题 .采用多个高速 DSP TMS32 0 C30和 TMS32 0 C50并行处理 ,结合 FPGA实现实时智能化图像跟踪 ,提出了概率模板分步搜索快速互相关算法 .互相关图像跟踪器的跟踪精度可达± 1个像素 ,而平均帧处理时间仅为 15ms,实验结果证明跟踪效果良好 .To research the technique of the high speed parallel correlation image tracking device and resolve the problem of tracking the low contrast targets with a complicated background, the parallel processing method was adopted based on the high speed FPGAs, DSPs TMS320C30 and TMS320C50 to realize real time intelligent image tracking. A fast speed correlation algorithm PMSS(probability model step searching) was proposed. The tracking precision of this correlation image tracking device was ±1 pixel, while the processing time of one frame was within only 15 ms. The test showed that the tracking effect was good. This correlation image tracking device is able to resolve the problem of processing speed existing in the current image tracking devices.
