Summary:In optical metrology, fringe projection is considered to be one of the most reliable techniques for recovering the shape of objects. For this technique, however, it is challenging to measure objects with a large variation in surface reflectivity, e.g. a scenario containing both dark and bright objects. Researchers have thus developed various approaches to high dynamic range (HDR) three-dimensional (3D) measurements over the years. In this paper, we present an overview of these techniques, as well as a new and definitive classification for them. We implement a set of representative techniques to measure objects with different characteristics of reflectance and discuss the advantages and constraints of the techniques according to the comparative results. Moreover, challenging problems and future research directions are discussed to advance HDR 3D measurement techniques.
