Abstract: Recently, the 3D reconstruction of indoor scene becomes a hot spot of research, as the popular of virtual house. Based on image understanding, this paper proposes an image-based box modeling method of 3D indoor scene reconstruction. Firstly, the vanishing points of indoor scene image are detected to represent the main axis of the room. With the analysis of algorithm??s influence factors, this paper improves the vanishing points detection algorithm to       ensure efficiency and accuracy. Then, this paper recovers automatically the scene spatial layout information with the layout reasoning steps which significantly improve the result. Finally, the calculation of camera parameters is       performed by using vanishing point, so the conversion from image scene to 3D model is implemented. The experiments demonstrate that the proposed method can quickly analyze the indoor scene images and detect the 3D layout for virtual scene reconstruction.
