摘　　要：成像制导武器系统进行多目标实时跟踪时,必须具备实时目标特征提取能力。实现一种基于TMS320C64x DSP平台的实时目标特征提取算法。针对C64x DSP的增强存储器访问特性,通过多像素信息的同步提取和像素归并方法,对算法进行优化。实验结果表明,优化后算法的执行效率和实时性较高。Imaging-guided weapon system must have the capability of real-time extraction for target feature during multi-target real-time tracking. This paper realizes a real-time extraction algorithm for target feature based on TMS320C64x DSP platform. According to the enhanced memory access characteristics of C64x DSP, the algorithm is optimized by using multi-pixel information synchronization extraction and pixel merging approach. Experimental results show that the optimized algorithm has high implementation efficiency and high real-time performance.
