In this process, the camera needs to shoot a surface with uniform illumination in the whole field of view to test the image unevenness brought by the camera. Typically, for cameras within 150 degrees, only a uniform planar light source or a uniform reflecting plane needs to be photographed to complete the calibration. However, for ultra-wide angle cameras with field angles in excess of 150 degrees, and even 180 degrees, it is relatively difficult to test the brightness and color temperature non-uniformity of the image.
