摘　　要：设计了一种视觉自动对准系统,分析了系统设计时各关键技术环节。基于双核控制,设计了基于FPGA控制CCD图像采集和基于Nios Ⅱ的多种内核,重点介绍了传动轴的角度量控制模型,设计了基于Nios Ⅱ的LCD驱动以实现液晶显示、基于ARM的触摸屏输入以实现人机交互以及AT91SAM7S64驱动以实现ARM与PC的数据传输等。实验结果表明,本系统具有应用价值高、速度高、可靠性高、故障少等优点。A sort of design technique of vision automatic alignment system was given. All kinds of key techniques were analyzed in system design. This system was based on two core control. Data acquisition of CCD image signal based on FPGA and many core based on Nios II were devised. This paper mainly introduced the control model of angular metric of power drive shaft, the design of LCD drive based on Nios II for realizing LCD display, the design of touch screen based on ARM for realizing human-computer interaction, the design of AT91SAMTS64 drive for realizing data transmission of ARM and PC and so on. Experiments showed that this system had advantages of high application value, high rate, high reliability and less accident.
