MULTI-PROJECTOR 3D SCANNING SYSTEM AND METHOD FOR PERFORMING SAME

A system for performing 3D scanning of an object using multiple projectors projecting a grid of source light signals on surface points of the object, with at least two of the projectors projecting overlapping source light signals; multiple cameras capturing images defining a grid of corresponding light intensities on the outer surface of the object varying over time to define a received light signal for each surface point; and a computing device controlling each one of the projectors such that each source signal of the grid of source light signals projected therefrom has a unique signal characteristics allowing a subsequent demultiplexing of received light signals for surface points where the source light signals of at least two overlapping projectors are combined, and perform signal processing on each received light signal to isolate therefrom constituent source light signals having the unique signal characteristic associated to a corresponding one of the projectors
