新型激光成像雷达图像匹配处理机的设计与实现
Hardware design of new type image matching machine for imaging laser radar
摘要
激光成像雷达是一种新型成像雷达,图像匹配处理机的使用是该雷达导航应用的先决条件之一.对激光成像雷达的图像匹配处理机进行分析,再进行设计.采用以高速DSP为主处理器,以大规模FPGA为处理器的图像匹配处理机的硬件方案.该方案计算能力强大且可扩展性强,通信接口多样可靠,算法软件实现可灵活修改.实验结果表明,该系统具有高实时性、高数据吞吐率、高可靠性、结构灵活的特点,为激光成像雷达在图像匹配导航中的应用研究提供了强大的处理平台.
Abstract
Imaging laser radar is a new type imaging radar. Image matching machine is one of the key foundations for the radar used in imaging navigation application. In this paper, the demands of the machine are analyzed at first. Then the machine with the scheme of DSP ＋FPGA is designed and implemented.The scheme has great capability on calculating and extensibility.It has a steady and various communication interfaces. And the software implement of algorithm can be modified easily.The experimental results show that the system works well for the application with high real-time,high reliability,and flexible architecture.
