Using adaptive regional projection to measure parts with strong reflection

In the trends of intelligent manufacturing, fringe projection profilometry is one of the most widely used techniques for obtaining three dimensional (3D) cloud of parts. However, this measuring technique may introduce interreflections by parts with strong reflection, which leads to phase calculation and 3D point reconstruction mistakes. In this paper we proposed adaptive regional projection method to measure interreflections area of parts with strong reflection. For a parts to be measured, we detect the surfaces of interreflections on it and give their pose in optical measurement system firstly. Then the system measure interreflections areas one surface by one surface. We measure complete cloud of a parts with strong reflection as the experiment, which illustrates our method is feasible.
