A Practical Approach for 3D Building Modeling from Uncalibrated Video Sequences

This paper presents an approach for reconstructing a realistic 3D model of a building from its uncalibrated video sequences taken by a hand-held camera. The novelty of this approach lies in the integration of some prior scene knowledge in the auto-calibration stage of the structure from motion (SFM) problem. The line parallelism and plane orthogonality are transformed into the constraints on the absolute quadric during camera auto-calibration. This make some critical cases solvable and the reconstruction more Euclidean. The approach is implemented and validated using simulated data and real image data. The experimental results in the end of the paper show the effectiveness of our approach.
