Direct Recovery of Planar-Parallax from Multiple Frames
In this paper, we present an algorithm that estimates dense planarparallax motion from multiple uncalibrated views of a 3D scene. This generalizes the “plane+parallax” recovery methods to more than two frames. The parallax motion of pixels across multiple frames (relative to a planar surface) is related to the 3D scene structure and the camera epipoles. The parallax field, the epipoles, and the...
متن کاملDirect recovery of shape from multiple views: a parallax based approach
Given two arbitrary views of a scene under central projection, if the motion of points on a parametric surface is compensated, the residual parallax displacement eld on the reference image is an epipolar eld. If the surface aligned is a plane, the parallax magnitude at an image point is directly proportional to the height of the point from the plane and inversely proportional to its depth from ...
متن کاملModel Refinement from Planar Parallax
This paper presents a system for refining the accuracy and realism of coarse piecewise planar models from an uncalibrated sequence of images. First, dense depth maps are estimated by aligning a planar region of a scene in each image, approximating camera calibration, and generating dense planar parallax. These depth maps are then robustly fused to obtain incrementally refined surface estimates....
متن کاملShape recovery from multiple views: a parallax based approach
Given two arbitrary views of a scene under central projection, if the motion of points on a parametric surface is compensated, the residual parallax displacement eld on the reference image is an epipolar eld. The parallax magnitude at a point, after suitable scaling, is an a ne invariant; if the surface aligned is a plane, it is directly proportional to the height of the point from the plane an...
متن کاملDuality, Rigidity and Planar Parallax
We i n vestigate the geometry of two views of seven points, four of which are coplanar, and the geometry of three views of six points, four of which are coplanar. We p r o ve that the two are dual, and that the fundamental geometric constraints in each case are encapsulated by a planar homology. The work uniies a number of previously diverse results related to planar parallax, duality and plana...
