Web-based 3D Media Information System

This paper introduces web-based 3D media information system. We first address two promising 3D modeling techniques, i.e., image-based 3D modeling and laser scanning based 3D modeling. Especially, we present two approaches of the image-based 3D modeling. One is an off-line approach using multiview images which is captured with single camera and a robot arm. The another one is an on-line approach that extends a commercial triclops camera system. We also utilize a 3D modeling scheme based on a laser scanner and a 3D reverse modeler. Using our 3D modeling environments, we construct several kinds of 3D models. We also implement web-based 3D media information management and retrieval system using XML data server, which provides services of 3D models. Our web-based 3D media information system has a goal of services of various types of 3D models and contents through WWW, which is currently focused on the development and management of 3D models of Korea cultural heritage.
