摘　　要：以MT9M034作为光电成像元件,CYUSB3014作为主控芯片,通过GPIF II接口采集CMOS图像传感器的数据,并为每一帧数据添加UVC视频数据标头,将其转换为符合UVC协议标准的视频数据,最后通过USB3.0接口以乒乓DMA的方式将其传送至PC,实现了免驱动、高速率、高分辨率的UVC视频设备。实验结果表明,该系统运行稳定,传输速率高,更换CMOS图像传感器可以制成不同规格的UVC视频设备,具有良好的推广价值。A USB3.0 video acquisition system based on UVC protocol is designed. The MT9M034 is used as the photoelectric device and the CYUSB3014 is used as the controller chip. CYUSB3014 acquires the data from CMOS image sensor,then converts the data to video that conforms to the UVC protocol. At last, the video data is transferred to PC through the USB3.0 interface in the way of ping-pong DMA, so a UVC video equipment of free-drive, high-speed, high-resolution is achieved. The experiment results show that the system runs stably,has high transmission rate,and can be made into different specifications of UVC video equipment by replacing the CMOS image sensor. The system has a good value for promotion.
