A robust and dynamic scene geometry acquisition technique for a mobile projector-camera system

Abstract

This paper presents a new structured light pattern generation technique, which allows acquisition of scene geometry from a single image, under various projection conditions with relatively high acquisition density. We construct the pattern by using the geometrical constraints of the projector-camera system, and solve the correspondence problem based on the local connectivity of the feature points and edges of the projection pattern. This method is robust from image processing perspective, and allows rapid geometry scanning using a mobile projector-camera system.
