Toward building 3D model of Vietnam National University, Hanoi (VNU) from video sequences

Abstract

3D models are getting more and more attention from the research community. The application potential of 3D models is enormous, especially in creating virtual environments. In Vietnam National University - Hanoi, there is a need for a test-bed 3D environment for research in virtual reality and advance learning techniques. This need raises a very good motivation for the research of 3D reconstruction. In this paper, we present our work toward the creating of a 3D model of Vietnam National University - Hanoi automatically from image sequences. We use the reconstruction process proposed in [1], which consists of four main steps: Feature Detection and Matching, Structure and Motion Recovery, Stereo Mapping, and Modeling. Moreover, we develop a new technique for the structure update step. By applying proper transformation on the input of the step, we have produced a new simple but effective technique which has not been considered before in the literature.
