Planar Region Detection and Motion Recovery
This paper presents a means of segmenting planar regions from two views of a scene using point correspondences. The initial selection of groups of coplanar points is performed on the basis of conservation of two five point protective invariants (groups for which this invariant is conserved are assumed to be coplanar). The correspondences for four of the five points are used to define a projecti...
متن کاملHomography-Based Positioning and Planar Motion Recovery
Planar motion is an important and frequently occurring situation in mobile robotics applications. This thesis concerns estimation of ego-motion and pose of a single downwards oriented camera under the assumptions of planar motion and known internal camera parameters. The so called essential matrix (or its uncalibrated counterpart, the fundamental matrix) is frequently used in computer vision ap...
متن کاملFeature correspondence and motion recovery in vehicle planar navigation
This paper describes a strategy to feature point correspondence and motion recovery in vehicle navigation. A transformation of the image plane is proposed that keeps the motion of the vehicle on a plane parallel to the transformed image plane. This permits to de"ne linear tracking "lters to estimate the real-world positions of the features, and allows us to select the matches that accomplish th...
متن کاملRecovery of Ego-Motion Using Region Alignment
A method for computing the 3D camera motion (the egomotion) in a static scene is described, where initially a detected 2D motion between two frames is used to align corresponding image regions. We prove that such a 2D registration removes all effects of camera rotation, even for those image regions that remain misaligned. The resulting residual parallax displacement field between the two region...
متن کاملRecovery of Ego Motion by Region Registration
A robust method is introduced for computing the camera motion the ego motion in a static scene The method is based on detecting a single image region and com puting its D motion in the image plane directly from image intensities The detected D motion of this image region is used to register the images so that the detected image region appears stationary The resulting residual displacement eld f...
