A Rapid Calibration Method for the Laser Scanning 3D Measurement System

A rapid calibration method for the parameters of a laser light plane scanning 3D measurement system is proposed. The mathematic model and the calibrated parameters of the measurement system are presented. A novel orthogonal calibration jig composed of two orthogonal planes is designed. The CCD camera parameters and the light plane parameters of the measurement system can be rapidly calibrated with the orthogonal calibration jig. The laser scanning 3D measurement system is calibrated with the calibration jig. A standard plane is measured at different positions. The accuracy is better than 0.1mm.
