Motion From 3D Line Correspondences: Linear and Non-Linear Solutions

We address the problem of aligning two reconstructions of lines and cameras in projective, affine, metric or Euclidean space. We propose several 3D and image-related linear algorithms. The result can be used to initialize the non-linear minimization of several proposed error functions, as well as the maximum likelihood estimator that we derive. We evaluate and compare our algorithms to existing...

Determining motion from 3D line segment matches: a comparative study

Line segment representations Motion estimation is a very important problem in dynamic scene analysis. Although it is easier to estimate motion parameters from 3D data than from 2D images, it is not trivial since the 3D data we have are almost always corrupted by noise. This article presents a comparative study on motion estimation from 3D line segments. Two representations of line segments and ...

Semi-Global 3D Line Modeling for Incremental Structure-from-Motion

Recovering 3D information from a single moving camera is a widely studied field in the area of computer vision (e.g. [1]). Most of these Structurefrom-Motion (SfM) approaches are based on so-called interest points (e.g. corners) in images, which can be accurately matched using powerful descriptors like SIFT [7]. Hence the output is usually a sparse 3D point cloud along with the camera poses for...

On-line Motion Retargetting

This paper presents a method to retarget the motion of a character to another in real-time. The technique is based on inverse rate control, which computes the changes in joint angles corresponding to the changes in end-effector position. While tracking the multiple end-effector trajectories of the original subject or character, our on-line motion retargetting also minimizes the joint angle diff...

Real-time Line Detection and Line-based Motion Stereo

Recognition of shape is one of the fundamental problems in computer vision. A number of fast line detection and line-based depth recovery algorithms have been developed on various parallel architectures to meet the requirement of real-time robotic vision. This thesis describes a parallel and hierarchical (pyramidal) approach to fast Hough line detection and line-based motion stereo. The lines a...
