Laser processing calibration method and device, processing equipment and storage medium

The invention is applicable to the technical field of image processing, and provides a laser processing calibration method and device, processing equipment and a storage medium, the laser processing calibration method comprises the following steps: generating a plurality of laser mark points by irradiating a machine tool plane through laser according to preset laser mark information and machine tool coordinates of an initial mark point on the machine tool plane; according to the preset laser mark information and the machine tool coordinate of the starting mark point, determining the machine tool coordinate of each laser mark point on the machine tool plane; acquiring image coordinates of the laser mark points on an imaging plane; and mapping the machine tool coordinates of the laser mark points and the image coordinates of the laser mark points one by one so as to determine the mapping relation between the imaging plane and the machine tool plane. According to the calibration method for laser processing provi
