Abstract
A method for verifying scan precision of a laser measurement machine includes the steps of: preparing a standardized 3D profile model; determining an ideal curved surface as a conventional true value of the standardized 3D profile model; scanning the standardized 3D profile model by the laser measurement machine and obtaining point cloud data; calculating a bias between each point in the point cloud and the ideal curved surface; evaluating the veracity of the laser measurement machine by using the largest bias; and evaluating the receptiveness of the laser measurement machine.
