Real-time depth warping for 3-D scene reconstruction

This paper explores a new depth-recovery technique targeted for two environments: visualization on non-regular screen surfaces, and real-time depth recovery in an unknown scene. The algorithm is based on the computation of pre-warped images that are projected into the scene and re-imaged by synchronized cameras. The real-time control of the pre-warp and the type of imagery projected into the scene allows for a novel solution that recovers scene geometry and can be used in both visualization (projection of imagery onto screen surfaces) and computer vision environments.
