摘要
根据深空背景的特点,以高性能数字信号处理器TMS320C6203为核心,结合现场可编程门阵列(Field Programmable Gate Array,FPGA)对采集的视频数字图像进行预处理和实时分割,实现了高帧频大视场实时目标检测系统。文中重点介绍了系统的硬件结构、软件流程,以及采用的目标检测算法。工程实践表明,本系统稳定可靠,可实时检测信噪比(Signal Noise Ratio,SNR)约为2.0的弱小目标。
A real-time target detection system is designed for the multiple targets detection in large field and deep sky. The system implements the target detection of high frame rate and large field, taking TMS320C6203 as its main processor and Field Programmable Gate Array （FPGA） as a preprocessor. The hardware structure, software flow of the system and the algorithm of target detection are introduced. The experiment results indicate that the system is stable and reliable to detect small targets whose SNR is 2.0 in real time.
