基于图像的三维分层重构算法研究

Image-Based 3D-Reconstruction Research

文章研究在摄像机内参数不变的情况下,利用图像中场景的结构信息实现分层重构的方法。通过求解基础矩阵实现射影重构,通过求解无穷远平面单应矩阵实现仿射重构,利用虚圆点约束求解绝对二次曲线的像实现欧氏重构。实验表明所研究的算法是有效可行的。

Under the fixed camera internal parameters circumstance,introduces the algorithm that use scene structure information to realize hierarchical reconstruction as follows:realizing projective reconstruction by solving fundamental matrix;realizing affine reconstruction by solving infinite homography;making out the absolute conic images by using constraints of circular points ,then realizing metric reconstruction. The experiments show that the algorithm is feasible.
