摘要
文中构建了以TMS320DM642为核心的硬件图像跟踪处理系统,但TMS320DM642的CPU片内内存较小,大量的图像数据无法一次移入TMS320DM642的CPU片内内存,这就使得现有的图像相关跟踪算法无法在TMS320DM642上快速运行。针对这一问题,本文在SSDA算法的基础上提出了一种新的相关跟踪算法,使之在保持SSDA算法的跟踪精度、可靠性、抗干扰能力的同时可以高速运行在小内存的DSP系统上。
In this paper we have designed a hardware image tracing processing system based on TMS320DM642.However internal storage of the CPU chip for TMS320DM642 is very limited and a two - step SSDA image tracing algorithm cannot he run quickly. So we have improved the algorithm and made it remain its original tracing preciseness, reliability and antijamming ability. In the meantime it can he used for a DSP system with limited internal storage in high speed.
