Abstract

Method for validating the scan precision of laser measure machine is disclosed. The method includes steps: doing a three dimensions standard pattern with sphere type; establishing norm of measurement and scanning the standard pattern with high precision contacting scanning machine based on the norm and then getting point-cloud data; fitting ideal curved face with the point-cloud data and defining it as nominal truth value; scanning the standard pattern based on the norm with the laser measure machine and getting point-cloud; calculating windage between the scanning point of laser and the ideal curved face, and using in the accuracy parameter; repeating measurement on the same scanning mode and on the same scanning parameter, estimating the consistent degree among the windages that between the point-cloud and the ideal curved face.
