Abstract

The three-Dimensional models of parts are the basis of virtual maintenance. In this paper, a three-Dimensional modeling system based on laser scanning is designed, and a novel calibration method is proposed. In calibration, a standard ball with known dimension is translated linearly and cut by the laser plane. The profile of the laser stripe is detected in subpixel precision. And sufficient accurate calibration points with different height are obtained. Then a mapping table is builded between the image plane and the laser plane. Through looking up the mapping table and interpolation method, the three-dimensional points cloud of the parts is obtained. This calibration method is low-cost, simple-operation and robust. And accurate and fast modeling for parts can be realized.
