3D Light Source Direction Estimation Using Known Objects for Augmented Reality
Yusuke Mukai, Hiroki Takahashi (UEC)
Abstract (in Japanese) (See Japanese page) 
(in English) In AR (Augmented Reality) technology, it is important to keep consistency between a real environment and a virtual environment. It is necessary to render shades and shadows of virtual objects accurately to achieve optical consistency. In this paper, we estimate external camera parameters from a single image using a cube as a known 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 from images with different conditions using the proposed method in a real environments and discussed estimation accuracies.
