从建筑物序列图像恢复三维结构

3D building structure from image sequence

介绍了一种从包含建筑物的序列图像恢复其三维结构的算法 .首先用基于矩阵分解的方法在相似变换意义下恢复目标的三维结构 ,然后用光束法平差提高三维结构的精度 .仿真试验和实拍图像试验均表明 ,该算法得到了精确、可靠的结果 .该算法能应用于城市建筑物设计、工业检测。

A method of 3D building structure from image sequence is presented. First, structure from motion ups to a similar transform based on factorization. Second, the structure accuracy is improved with bundle adjustment . Synthetic and real image tests show that this method gives accurate and robust results. It can be applied to building design, industry detection, virtual real ity, etc..
