嵌入式DSP激光雷达距离图像处理系统

介绍了一种基于数字信号处理器（DSP）的嵌入式激光雷达图像采集系统的实现原理、硬件结构和软件设计。系统用双口RAM和CPLD采集激光雷达距离数据，经过伪彩色编码后距离图像显示在彩色液晶上。系统用DSP对距离图像进行二值化和非线性滤波处理后，通过连通域搜索提取出目标区域。实验结果表明该系统可满足激光雷达性能测试要求，为激光雷达成像系统研制提供了可靠的现场测试工具。

An Embedded DSP System of Laser Radar Range Image Processing

An embedded image acquisition system of laser radar based on digital signal processor(DSP) is presented,whose theory of realization, hardware structure and software are also introduced.This system applies a DUALRAM and CPLD to the range data acquisition of laser radar,and then by pseudo coding,the range image is displayed on a color LCD.In this system,after binarization and nonlinear filtering of range image with DSP,the object region is obtained by connecting area searching.The experiment results show that this system can satisfy the demands of laser radar testing and will be a good field-testing tool for laser radar imaging system.
