Paper Abstract

We present a general and effective projector calibration method using a ray-based generic model, which consists of rays projected from all pixel elements of the projector. For computing the parameters of the rays, we propose a flexible 3D coordinates calculation method for the projected calibration target. Since the ray-based generic model does not rely on any assumption, our approach is applicable to arbitrary projection system. The calibrated rays can be applied to evaluate projector's actual distortion model, reconstruct 3D points of the scene and correct geometric distortion of the projected image etc. Experiments are presented to verify the performance of the proposed technique.
