基于DSP和CPLD的激光雷达图像采集和显示集成系统

介绍了一种以DSP和CPLD为核心的激光雷达图像采集系统,阐述了系统工作原理、系统结构和软硬件设计.系统以TMS320VC5402DSP芯片作为系统控制和图像处理的核心,通过双口RAM接收激光雷达图像数据,用CPLD根据场、行、列、写雷达图像4个同步输入信号生成双口RAM的地址信号实现图像存储,原始图像和处理后图像显示在彩色TFT液晶屏上.此外,系统还可通过USB接口与PC机通信实现图像的存储和回显功能.该系统为激光距离成像雷达以及距离图像的研究提供了一种有效的分析和测试工具.

Laser radar image acquisition and display integrated system based on DSP and CPLD

A laser radar image acquisition system based on DSP and CPLD, its operating principle, makeup, hardware and software design are discussed with TMS320C5402DSP used as the controlling and image processing core in the system, the laser radar image data is acquired and stored by a DUALRAM, and their address signals are generated by CPLD according to four image synchronization signals: FRAME, LINE, COL and WRITE. Finally, the original image and processed image are both displayed on the color TFT-LCD. In addition, by USB interface this system can communicate with PC and implement image storage, redisplay. Generally, this system provide a powerful analysis and testing tool for the study of Laser range imaging radar and range image.
