一种三维准欧氏重建方法

研究在不必精确知道相机内参数的情况下进行场景的三维重建，充分利用建筑场景的平面信息，假设场景由一些基本平面元素组成，从而自动生成场景的拓扑结构．虽然重建结果从严格意义上仍是射影重建，但已经非常接近欧氏重建结果，文中称之为准欧氏重建，该结果还可以为其它优化算法提供很好的初值．真实图像的实验结果证实了本文算法，重建模型达到了很好的可视效果．

3D Quasi-Euclidean Reconstruction Method

This paper presented a method of 3D reconstruction without knowing camera intrinsic parameters accurately, planar information was used to automatic generation of architecture meshes on the assumption that scene is make up of planes. Though strictly speaking, the result was only projective reconstruction, but it was very close to the result of Euclidean reconstruction, named Quasi-Euclidean reconstruction. The result of our method gate a good initial value for other optimization methods. Real image data demonstrate this method, which gave a good 3D visual model.
