The adjustment of the camera in hardware mainly adjusts the quality of the image by adjusting the aperture

and focal length, but after the camera is installed, it cannot be adjusted casually. After the hardware adjustment

is completed, the environment light source and camera parameters are usually adjusted to improve the software

imaging effect.

Contrast: Mainly by adjusting the difference between the background color and the material color to fine-

tune the image quality.

Gain: It is the magnification times relationship of image brightness.

Exposure: the longer the exposure time, the higher brightness of the image.

Continuous auto exposure: The software will automatically adjust the above exposure value. When the

exposure value is adjusted automatically to a stable level, need to uncheck it.

Parameter 1, Parameter 2: When the external environment has a greater impact on the imaging quality,

two sets of parameters can be used for recognition.

Rotation angle: The imaging angle of the image display area is rotated.
