Abstract :
An original procedure is presented for calibrating fringe projection-based 3D vision systems. The approach estimates both the phase-to-depth and transverse relationships by using the phase maps calculated for only three planes placed within the calibration volume. Experimental tests conducted on a fringe projection system show the effectiveness of the proposed procedure.
