Abstract:In this paper, we propose a real-time 3-D shape measurement system which consists of 1) a moving fringe projector for spatio-temporal encoding (single frequency in time but different phase in space) of illumination angle, and 2) the three-phase correlation image sensor (3PCIS) which performs the synchronous detection and amplitude/phase demodulation of intensity-modulated light in real time on each pixel. The 3PCIS demodulates amplitude and phase of moving fringes in a scene frame by frame. Then, it is unwrapp… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
