Abstract

Mixed reality (MR) technology can be applied to various applications such as architecture, advertising, and navigation systems, so the desire to utilize MR in outdoor environments has been increasing. In order to utilize MR, it is necessary to achieve alignment super imposing virtual contents in the desired position. However, because light changes continually in outdoor environments, and the appearance of real objects changes also, in some cases the previous image-based alignment methods do not work well. In this paper, a robust image-based alignment method to be used in outdoor environments is proposed. In the proposed method, the albedo of real objects is estimated using 3D shapes of these objects in advance, and the appearance is reproduced from the albedo and current light environment. The appearance of real objects and reproduced image becomes close, so a robust image-based alignment is achieved.
