A Calibration Method of Monocular Stereo Vision System for On-machine Measurement

摘要

A calibration method of movable monocular stereo vision measurement system for on-machine measurement was presented based on standard dimension. The physical model and mathematical model was established in view of perspective projection transformation. Structure parameters of this stereo vision system were determined using Levenberg-Marquardt algorithm. Experiment results show that this calibration method can achieve precise camera parameters and three dimensional space coordinates and can be employed conveniently in real industrial environment.
