Paper Abstract

Several light incisions brought up when the large size workpiece was scanned along the cross-section by laser light structure sensors. Since discrete points of each light incision were fitted to elliptic curve, 3D coordinates of the center of the light incision plane could be attained. With the space line fitting and error examination algorithm, the large cross-section workpiece straightness was gained, and the geometry of cross-section could be calculated. This paper brought forward the method and mathematics model of straightness measurement of the large-size workpiece by laser vision, and experiment result was also given out.
