3D surface reconstruction and panorama stitching based on LCD-based calibration and multi-baselines stereo matching

Abstract

This paper presents an automatic method of 3D surface reconstruction and panorama stitching based on LCD-based calibration and multi-baselines stereo matching. In the method, calibration is carried out using a 2D control field composed by the completely flat Liquid Crystal Display (LCD), on which lots of circle points with known coordinates are drawn by a simple program. Then, the technology of multi-baselines stereo matching is introduced and applied to get highly reliable corresponding points to achieve good triangulation results using fast bundle adjustment. Finally, methods for 3D surface reconstruction and panorama stitching are also introduced.
