Abstract:

Camera calibration is the most important step for stereo vision measuring techniques, which effects the accuracy and stability of the measuring system directly.A practical binocular stereo calibration method is proposed in this paper.The calibration is done by just taking several images of a specialdesigned planar board in different orientations.Based on an existing algorithm that is mainly used for single camera calibration, the relative orientation and location between the two cameras are further optimized to adapt the algorithm to binocular stereo system.
