Semiconductor refrigerating device detecting, reading and matching system and method based on machine vision

The invention discloses a semiconductor refrigerating device detecting, reading and matching system and method based on machine vision. The method comprises the steps: placing a semiconductor refrigerating device on a checkerboard with a known specification, and acquiring a surface image of the semiconductor refrigerating device through an industrial camera; performing distortion correction and restoration on the image by utilizing machine vision software according to the specification of the checkerboard to obtain a real image; identifying a semiconductor refrigerating device based on the real image; judging whether a semiconductor refrigerating device needing to be matched exists or not; if yes, positioning and identifying the semiconductor refrigerating device which is not matched, and identifying the two-dimensional code of the current positioned semiconductor refrigerating device to obtain a character string; judging whether the currently positioned semiconductor refrigerator is matched with the correspo
