Sažetak:
Human body scanners using structured light are usually comprised of one projector which provides a limited view of the body surface due to limited field-of-view. To scan the whole surface of a human body multiple projectors must be used. Using more than one projector in a structured light scanner is typically difficult due to inter-projector interferences which make surface reconstruction a hard task. We propose to use temporal phase-shifts to enable multiplexing in fringe-projection profilometry. In our approach each projector projects a sinusoidal fringe pattern having its own specifically chosen set of temporal phase shifts so for a system of  projectors all temporal phase shifts together comprise a DFT_2*P+1 basis. Such choice of temporal phase shifts enables simple and efficient separation of the combined pattern into the contributions of each projector. The proposed approach places no constraints on the number of projectors and on spatial projector placement. We demonstrate the applicability of the proposed approach on a prototype human body scanner using three projectors and six cameras.
