Abstract (in Japanese) (See Japanese page) 
(in English) We are proposing a method that enables 3D structure estimation of a room based on a segmentation result. The
current problem of this method is the lack of a resistance machanism against image rotation. This research proposed a novel
method to improve the rotation resistance of the method, where the roll angle is estimated by gradients of lines composing the
center rectangle. Experimental results using 2D images generated from 3D CGs showed that the estimation error of the roll
angle by the propoed method became 0.07◦ .
