Calibration method and device for laser light-emitting indication points and galvanometer coaxial vision system

The invention relates to a calibration method and device for laser light-emitting indication points and a galvanometer coaxial vision system. According to the calibration method, a light-emitting markpoint array respectively corresponding to each preset photographing position point and a point array image respectively corresponding to each light-emitting mark point array are obtained respectively, a corresponding perspective transformation matrix and a standard image rotation angle corresponding to each point array image are calculated, a first coordinate of a real-time photographing positionpoint under a galvanometer coordinate system is obtained, a galvanometer is moved to the real-time photographing position point to trigger a camera assembly to photograph the real-time photographingposition point so as to obtain a product photographed image, according to the first coordinate, the perspective transformation matrix and the standard image rotation angle, rotation straightening andidentification processing ar
