Interactive 3-D modeling system using a hand-held video camera

Recently, a number of methods for 3-D modeling from images have been developed. However, the accuracy of a reconstructed model depends on camera positions and postures with which the images are obtained. In most of conventional methods, some skills for adequately controlling the camera movement are needed for users to obtain a good 3-D model. In this study, we propose an interactive 3-D modeling interface in which special skills are not required. This interface consists of "indication of camera movement" and "preview of reconstruction result." In experiments for subjective evaluation, we verify the usefulness of the proposed 3D modeling interfaces.
