摘要：

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. © 2014 Information Processing Society of Japan.
