摘要
利用视频输入处理器 (SAA71 1 1 )和现场可编程门阵列 (FPGA) ,采用全硬件方式和两帧轮换存储方式设计实现了图像采集系统、计算机以及前端硬件处理系统之间的相互接口 。
A hardware implementation solution to image acquisition in vision inspection based on special video decoder SAA7111 and FPGA (Field Programmable Gate Array) was proposed. Interfaces among the image acquisition system, the computer and the font end hardware processing system were successfully completed. Real time image capturing and real time image processing can be carried out simultaneously by using two frame memory to store image data in turn.
