【摘要】 图像采集处理系统是激光成像雷达系统的重要组成部分 ,文中简要介绍了一种主 /从计算机结构的图像采集处理系统的设计、组成、工作过程及软件流程。利用主 /从计算机的中断功能实现图像数据的帧实时采集、处理和显示。采用CPLD设计了专用的DMA控制器并与从计算机ADSP2 10 2 0共用两片相同的双端口存储器 ,通过同步切换存储器控制完成连续的图像缓存和采集处理。试验结果表明 ,该系统能很好地完成激光成像雷达的帧实时采集处理和显示。更多还原

【Abstract】 Image acquisition and processing are essential tec hn ologies in laser imaging radar system. Designing procedure and composition of th e image acquisition and processing based on Master/Slave (M/S) computer system a re presented. Interrupt functions of M/S computer system are utilized to perform frame-real-time acquisition, processing and displaying of laser image. A spec ial DMA controller is designed to co-occupied two identical dual-port SRAMs wi th slave computer ADSP21020, and successive image buffering, acquisition and pro cessing are implemented by exchanging enable rights of SRAMs synchronously. Fina lly, the experiment result analysis is given.更多还原
