以高性能数字信号处理器TMS320C6203为核心,结合CPLD（可编程逻辑器件）进行逻辑控制,用FPGA（现场可编程门阵列）进行预处理,设计了实时目标检测和跟踪系统。介绍了实时图像处理系统的硬件组成、工作原理、软件流程,重点分析目标检测算法和系统实时性。该系统被成功用于光电经纬仪红外图像处理系统中,经试验证明,系统对弱小目标的检测、识别和跟踪能力达到实际工程的实时性需求,大大提高了数据采集能力与处理速度,采样精度得到很大提高,完全满足系统设计要求。

A real-time target detection and tracking system is designed using TMS320C6203 high performance DSP （Digital Signal Processor） as the core, using CPLD （Complex Programmable Logic Device） for logic control and u- sing FPGA （Field Programmable Gate Array） for image preprocessing. The hardware structure, operation principle and software flow of the system are introduced with a highlight on the algorithm of target detection and real-time performance. The system is successfully used in the infrared image data processing system of a photo-electric theod- olite. Applications in range tests show that the dim target recognition and tracking capability of the system meets the real-time performance requirements of engineering projects. Significant improvements are made in data acquisition capability, data processing speed and sampling accuracy.
