产品规格书查看深圳触觉智能官网-产品中心 01 确认USB摄像头设备节点
主板接上USB摄像头后使用以下命令查看USB摄像头的设备节点
rootido:~# v4l2-ctl --list-devices
rkisp-statistics (platform: rkisp):/dev/video7/dev/video8rkisp_mainpath (platform:rkisp-vir0):/dev/video0/dev/video1/dev/video2/dev/video3/dev/video4/dev/video5/dev/video6/dev/media0AC_2019053011080005: ZH-0305 (usb-xhci-hcd.4.auto-1):/dev/video9/dev/video10/dev/media1
video9即为USB摄像头的设备节点。
02 查看USB摄像头支持的图像格式
rootido:~# v4l2-ctl -d /dev/video9 --list-formats-ext --all
