In AR technology, it is important to synthesize virtual objects in real space so that users perceive the synthesis image as free of artificiality. Especially, it is the most significant to keep their optical consistency because it can reduce artificiality of the image. In this paper, we estimate external camera parameters from a single image using a cylindrical object and propose a method for estimating a light source direction in three dimensional space by using inverse perspective projection transformation. In addition, we estimated light source directions using the proposed method in a real environment and discussed the merits and demerits of the proposed method and a conventional method by comparing estimation accuracies of both methods. |
