基于影灭点的单视图三维重构

提出了一种单视图三维重构方法,该方法需要用户提供图像点及其对应三维点之间的几何信息.由于结构场景有大量平面构成,存在大量的平行性和正交性约束,所以该方法主要应用于结构场景的三维重构.重构过程分为两部分:首先,基于三组互相垂直方向的影灭点,对方形象素摄像机进行定标;然后,基于用户提供的共面性和场景平面的影灭线,计算点的三维坐标.采用真实图像测试,说明该方法有效且简单易用.

3D Reconstruction Using Vanishing Points From a Single View

In this paper,a method for performing single-view 3D reconstruction is present,in which the user provides image points and geometric information about the corresponding 3D points.The main application is to structured scenes,mostly planar structures where there are plentiful constraints to be had from parallelism and orthogonality.There are two components to the reconstruction process.First,the camera calibration is computed,that is to calibrate a square pixel camera from three vanishing points of orthogonal...
