Optical axis deflection angle detection method and device, equipment and medium

The invention discloses an optical axis deflection angle detection method and device, equipment and medium. The method comprises the steps of obtaining two original pictures; wherein the two original pictures are obtained by shooting the checkerboard at different shooting angles at the same target position through the same shooting device, and the image center of each original picture in the two original pictures is located on the corresponding checkerboard image; obtaining a first number and a second number of grid image boundaries between the image center of each original picture and two adjacent edges of the checkerboard image; determining a first distance and a second distance between the optical center of the shooting equipment and two adjacent edges of the checkerboard when the shooting equipment shoots the two original pictures according to the first quantity and the second quantity; and determining a deflection angle value between different shooting angles according to the parameter information of the
