A three-dimensional measurement method by combining binocular and monocular vision systems

Based on the combination of binocular vision measurement and monocular vision measurement, a new three-dimensional (3D) measurement method is proposed with the two systems, the common field of view is reconstructed by a binocular vision system, and the unmatched area is filled up by two monocular vision systems, which is composed of the projector and cameras separately. Their world coordinate systems can be unified to a common reference with uniform calibration. In the measurement of gesso head portrait, the data missing near the nose can be avoided by this method. While the reconstruction precision of the binocular vision system is maintained, this method improves the measurement results efficiently.
