建築画像の消失点検出手法の開発とそれに基づく3次元建築モデルの再構成手法

抄録

We present a method for detecting vanishing points of an architectural image, which consists of mainly parallel and orthogonal lines, and reconstructing a 3D architectural model. For this, we implement an algorithm for line detection from an architectural image, based on the Hough Transform employing the plane sweep technique and test its efficiency and ability of the line detection from digital images. We then apply it to architectural images in order to see the practical usefulness of the proposed method.
