| Abstract(in English) | In this paper, we propose a method for estimating the illumination distribution of a scene from image sequences of any arbitrary object in the scene. For estimating the illumination distribution of a scene, a method employing pixel values inside shadows cast by an object of known shape onto another object surface has been proposed. The method, however, requires the shape and size of the object, so it cannot be applied in wide field. In our method, first, we take an arbitrary object with a handheld camera and 3D reconstruct feature points of the object by factorization. Then, we estimate occluded areas of rays from light sources. As a result, we estimate the illumination distribution without the object of known shape. Experimental results show that our method can estimate the illumination distribution of a scene. |
