Abstract

In the traditional fringe reflection method for specular surface measurement, the change of phase is only due to the gradient changes. Through the gradient-based phase unwrapping algorithms eventually restored the surface shape. However, due to the approximate nature of the formula itself, the broadness and accuracy of measurement is limited in a certain range within. The actual change in phase comes from the gradient and the surface shape itself together. Therefore, the absolute phase and the surface shape model and the face shape recovery algorithm based on recursion were presented in this paper. Using the model in this paper largely makes up for the deficiencies of the traditional algorithm. A good effect in surface shape recovery has been achieved through the experiment.
