This paper describes a novel approach to the construction of a projector-based augmented reality environment. The approach is based on capturing the dynamic changes of surfaces and projecting the images within a large real environment using a system that includes a laser range finder and a projector, whose optical axes are integrated by mirrors. The proposed method offers two distinct advances: (1) robust 3-D viewpoint detection from consecutive range images, and (2) fast compensated image generation and presentation with view frustum clipping to measured surfaces. A prototype system is shown to confirm the feasibility of the method; it generates compensated images to suit the user's viewpoint that are then projected within dynamic real environment, in real-time.
