Plate defect detection method based on 2D and 3D images and related equipment

The invention provides a plate defect detection method based on 2D and 3D images and related equipment, and relates to the technical field of plate detection. The invention provides a plate defect detection method based on 2D and 3D images. The method comprises the following steps: acquiring all point cloud information, collected by a 3D camera, of the surface of a plate; on the basis of the variance of the coordinates of all the point cloud information in the Z-axis direction, abnormal point cloud information is determined and recorded as abnormal coordinates, and the Z-axis direction is the direction perpendicular to the surface of the plate; according to all the abnormal coordinates, determining an area where the abnormal coordinates are gathered, and recording the area as an abnormal area; acquiring image information of the abnormal area acquired by a 2D camera; and inputting the image information into an improved yov7 model for surface defect type detection, so that redundant calculation and memory acces
