3D object surface reconstruction using single camera

A flexible 3D reconstruction technique to easily used is proposed, based on structure from motion. The concrete method is shown as follows: the camera is calibrated and the intrinsic parameters is sotten using Zhang calibration method, then, the object in two different orientations and the motion need not to be known, after matching the two images robustly, the fundamental matrix and es- sential matrix from point correspondences are estimated, further, by decomposing essential matrix, the motion parameters ( , ) de- termined by the two different orientations is solved and the projective matrixes corresponding the two orientations is obtained. In the end, the 3D coordinates of the object feature points is computed and the surface of the object in OpenGL is displaied. Compared with the clas- sical binocular vision system which use expensive equipments, this technique only requires a digital camera and a planar pattern, it is well suited for general digital camera users without specialized knowledge of 3D geometry.
