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 scene

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 and metric structure of each plane is computed

that is to calibrate a square pixel camera from three vanishing points of orthogonal directions and metric rectify each plane by computing the imaged circular points and the vanishing line. The second stage involves stitching the individually rectified planes together

accounting for the arbitrary scale factors in the rectification of each plane and the relative orientation of planes not known to be orthogonal. Real image have been used to test the proposed method

and good results have been obtained and have demonstrated the proposed method is easy to use.
