UVC CAMERA CONTROL WINDOWS SERIAL
If you want a different serial number, please contact us. Use the python nodeĭevice_file = "/dev/video Use the video node sudo udevadm info -query=all /dev/video0 | grep 'VENDOR_ID\|MODEL_ID\|SERIAL_SHORT' 3.2. We will introduce you to two ways to check the serial number. Arducam UVC camera comes with a unique serial number, it allows you to recognize and control the camera separately. Sometimes you want to connect multiple UVC cameras at the same time but hard to identify them. Please refer to here for more information about OpenCV access to the camera. Please refer to here for more control parameters. # When everything done, release the capture # The control range can be viewed through v4l2-ctl -L Use python OpenCV to access the camera(OpenCV can be installed via Pip, code: pip install OpenCV-python). Access the camera and Send control with OpenCV v4l2-ctl -list-formats-ext -d 0 # 0 is video0 2. Use the following command to check resolutions and frame rates supported by each format, if you want. The following pictures are example of the UVC camera with four video nodes. v4l2-ctl -list-formats -d 0 # 0 is video0 Use the following command to view the supported formats. For cameras with four nodes, the video0 formats including YUV, MJEPG, etc, and video2 is H.264.For cameras with two nodes, the video0 formats including YUV, MJEPG, etc, and video1 is H.264.In General, cameras with H.264 encoding have two or four video nodes: Identify the Video Node, Supported Resolution, and Frame Rateīefore you opening a UVC camera, you have to check which is correct the video node.
