Undistorted projection onto dynamic surface

Abstract

For projector-based augmented reality systems, geometric correction is a crucial function. There have been many researches on the geometric correction in the literature. However, most of them focused only on static projection surfaces and could not give us a solution for dynamic surfaces (with varying geometry in time). In this paper, we aim at providing a simple and robust framework for projecting augmented reality images onto dynamic surfaces without image distortion. For this purpose, a new technique for embedding pattern images into the augmented reality images, which allows simultaneous display and correction, is proposed and its validity is shown in experimental results.
