基于机器视觉的嵌入式高速图像通信系统设计

介绍了DSP 与CPLD 协同控制的高速图像通信系统的设计。整个图像通信系统由图像采集、图像信号的处理和控制、USB 传输和控制、系统接口以及终端的图像还原和存储等
几部分组成。系统采用高速USB2.0 作为图像传输的接口。该系统已成功应用于一个图像处理和识别的高速和高精度工业项目中，由于图像信号不经过压缩处理对后续处理没有任何影响，因此这种图像处理和识别的效果比一般的图像采集要好，满足了特殊场合的特殊需要。关键字：机器视觉;数字信号处理系统;复杂可编程逻辑器件;图像采集;图像处理
Abstract: A design of high-speed image communication system which is controlled coordinately by DSP and the CPLD is introduced. The entire image communication system consists of image capture, image signal processing and the control, the USB transmission and the control, the terminal image return and storage and so on. The system uses high-speed USB2.0 interface as image transmission. This system has been applied successfully in a high-speed and high-accuracy industrial project of an image processing and the recognition. The image signal not passing through compression processing does not influence the following processing, therefore, compared with general image capture, the effect of the image processing and the recognition is better and it has met the special needs for special occasion.
