Abstract
Structured light three-dimensional (3D) imaging has been widely used for 3D surface measurement applications. However, it is limited for objects with high reflectivity in complex scenes. There are flying points or missing point clouds for the 3D imaging due to the overexposure by strong reflection or multiple reflections. In this work, we propose a method using two cameras to share the same projector. Gray codes with multi-step phase shift images compose the projected patterns. We adopt the partition fusion method for the captur images from different perspectives to reduce the influence of strong reflection and multiple reflections. The 3D measurement with the fusional captured images is realized.
