The invention relates to the technical field of three-dimensional imaging detection of steel plates, and particularly discloses a three-dimensional detection method for the surface of a medium-thickness plate, which comprises the following steps of: mounting a steel plate surface detector on a steel plate input roller way of a medium-thickness plate production line cooling bed; a laser detector and a digital camera of the steel plate surface detector adopt laser triangular positioning to collect a 2D image and a 3D image of the surface of the steel plate; adjusting the size of an effective photographing window of a digital camera of the steel plate surface detector at different running speeds of the steel plate; an image of the surface of a steel plate is collected through a system for detecting the surface of the steel plate, and the system post-processes an image detection result containing a large amount of information; after the images are collected, the system guides a user to sort defect images in a cla
