摘要：

This Letter proposes a novel approach, called multiview fringe matching profilometry (MFMP), for threedimensional (3D) measurement in a projector-camera system. An essential difference from the traditional optical profilometries in our MFMP test is that a projector will be regarded as a camera with the reverse lightpath and not just as a coding projection device. Therefore, profiting by a maximum utilization of a multiview matching relationship, the homonymy points can be directly found with the geometric constraint of the corresponding fringe images between the projector and cameras. Meanwhile, the 3D object reconstruction can be obtained quickly and accurately from a single fringe pattern without phase unwrapping, even if the discontinuous surface shape is also easily measurable in our MFMP. Experiment results are provided to verify the effectiveness of our approach. (C) 2018 Optical Society of America
