3D Reconstruction of Buildings Based on Image Sequence

摘要

A fast and flexible technique of 3D modeling of building based on image sequence has been proposed in this paper. It firstly describes the importance of the study in this area, then gives a detailed analysis of each step of the whole reconstruction process, including homonymy points selection, determination of key points' relationship, the solution method of splicing among points appeared on different stereo images, texture mapping and so on. Finally, real data has been used to validate the proposed technique, using VC++6.0 and OpenGL to realize the visualization of the buildings artificial interactively, and satisfied results have been obtained demonstrating the effectiveness and flexibility of the approach.
