Stereo vision plays an essential role in non-contact 3D measurement, which employs two cameras to achieve applications such as visual synthesis, terrain surveying, and deformation detection. The commonly used Scheimpflug principle is expressed as the object plane, the image plane, and the lens plane intersect in a line, based on which stereo cameras can be slantwise focused on the object space with an overlapping field of view and depth of field. Based on our previously proposed calibration method, a stereo-rectification of Scheimpflug telecentric lenses is proposed in this paper. The effectiveness and accuracy of the proposed methods are verified by experiments.
