3D Scene Reconstruction from Reflection Images in a Spherical Mirror
This paper proposes a method for reconstructing a 3D scene structure by using the images reflected in a spherical mirror. In our method, the mirror is moved freely within the field of view of a camera in order to observe a surrounding scene virtually from multiple viewpoints. The observation scheme, therefore, allows us to obtain the wide-angle multiviewpoint images of a wide area. In addition, the following characteristics of this observation enable multi-view stereo with simple calibration of the geometric configuration between the mirror and the camera; (1) the distance and direction from the camera to the mirror can be estimated directly from the position and size of the mirror in the captured image and (2) the directions of detected points from each position of the moving mirror can be also estimated based on reflection on a spherical surface. Some experimental results show the effectiveness of our 3D reconstruction method.
