| 摘 要： | 在FPGA图像采集系统的基础上,设计了一种遥控式且带存储功能的图像采集系统。设计采用MT9T001作为图像传感器,以FPGA芯片EP2C8Q208和AVR单片机ATmega8L的组合为主,以高速视频数模转换芯片ADV7125和USB接口芯片VNC1L-1A为辅助,完成了图像的采集、实时显示、图像以灰度位图格式的存储及对已存图片的重新显示、存储控制、遥控器解码及用遥控器调节图像参数等功能。此设计应用到工业相机领域,操作简单且方便灵活,对130万像素的图像数据实时显示的速度可以达25 f/s,写入存储设备和从存储设备中读出并显示的时间分别可达6 s和5 s。对图像存储功能的设计与实现进行了详细介绍,并对遥控功能进行了描述。
