On 3D Reconstruction from Two Perspective Views
A concise derivation is given for a compact nonlinear equation which specifies possible 3D rotations of rigid objects, compatible with measurements of five object points in two views. The insight provided by direct geometrical interpretation of this equation = which contains ULLMAN's polar equation as a special case-may be exploited for attempts to categorize the set of possible solutions.
متن کاملReconstruction of 3-D Symmetric Curves from Perspective Images without Discrete Features
The shapes of many natural and man-made objects have curved contours. The images of such contours usually do not have sufficient distinctive features to apply conventional feature-based reconstruction algorithms. This paper shows that both the shape of curves in 3-D space and the camera poses can be accurately reconstructed from their perspective images with unknown point correspondences given ...
متن کامل3-D polyhedral face computation from two perspective views with the aid of a calibration plate
The 3-D reconstruction of visible polyhedral faces from a pair of general perspective views with the aid of a calibration plate is addressed. A polyhedron is placed on a planar calibration plate and two side views of both the polyhedron and the calibration plate are taken. Through proper arrangements we may assume that in the two views a number of polyhedral edges lying on the calibration plate...
متن کامل3D Reconstruction from Two Views
In this project, we study a method to reconstruct a 3D scene from two views. First, we extract and match SIFT keypoints from two images, based on which we compute the fundamental matrix that relates the two images. Then we derive the camera matrices and reconstruct the 3D scene. To achieve better visual effects, we interpolate between the sparse 3D points. In order to do that, we first pick a p...
متن کاملQuan : Conic Reconstruction and Correspondence from Two Views 3
| Conics are widely accepted as one of the most fundamental image features together with points and line segments. The problem of space reconstruction and correspondence of two conics from two views is addressed in this paper. It is shown that there are two independent polynomial conditions on the corresponding pair of conics across two views, given the relative orientation of the two views. Th...
