Abstract

This paper presents our study on dynamic three-dimensional (3D) shape measuring technique, which is based on the idea of projecting and superposing a carrier fringe pattern onto the changing surface of a tested dynamic object, then recoding a sequence deformed fringe patterns from other view direction and reconstructing its 3D dynamic shape with 2D or 3D Fourier fringe analysis. This paper briefly reviews the basic principles and its typical applications of the combined technology based on grating projection and Fourier fringe analysis that we have developed over past ten years.
