This paper is aimed at presenting a 3D surface capture algorithm of underwater objects using multiple projectors and cameras with flat housings.We use a pixel-wise varifocal model to realize an efficient forward projection in order to explicitly account for refractions caused by flat housings and to improve appearance-based correspondence estimations.We propose a practical calibration procedure of underwater projectors, and show a real system which proves our concept.
