In the process of measuring highly reflective objects using binocular structured light 3D shape measurement technology, overexposure occurs at different positions of the corresponding object surface in the left and right images, resulting in invalid phase data in the corresponding area. First, the projection system as the reverse camera, and the multiple visual geometry system is composed of the binocular system and the projection system. Second, the more on every point on the surface of the object system matching. Then, the validity of the phase corresponding to each pixel is judged by modulation, and the two-view collinear equation is obtained by discarding the pixels in the over-exposed image region. Finally, the 3D point cloud reconstruction is realized by global multi-view equation. This method can effectively solve the problems of coordinate system transformation, data redundancy and fusion error of multi-system reconstruction results. The experimental results show that the proposed method can effectively measure the 3D shape of highly reflective objects in the field of view of 500 mm×700 mm.
