Some models of cameras may appear black when connected to a computer and displayed in the calibration tool. This may
be caused by the camera resolution. A tool can be used to view the camera resolution.
On the device, you can see the resolution and model of each USB camera connected to the computer. After selecting the
corresponding camera, the corresponding image can be displayed in the tool.
Open the resolution setting in the tool. You can modify the camera resolution. Click Settings and check if there is a
resolution of 640X480 in the video format-output size of the properties.
You can also use the camera that comes with the Windows operating system for viewing. If the above camera is normal,
it is recommended that you use the model recommended in our USB camera selection for testing.
