2D-3D pose estimation

[1988 Proceedings] 9th International Conference on Pattern Recognition, 2003
A robust technique is described for solving the 3D-to-2D perspective projection pose estimation problem, given corresponding point sets. The technique has a considerable advantage over the least-squares (LS) technique in that with as many as 30% of the corresponding point pair matches completely incorrect the robust technique can determine the correct ...

Polarimetric Relative Pose Estimation

2019 IEEE/CVF International Conference on Computer Vision (ICCV), 2019
In this paper we consider the problem of relative pose estimation from two images with per-pixel polarimetric information. Using these additional measurements we derive a simple minimal solver for the essential matrix which only requires two point correspondences.

Monocular Head Pose Estimation

2008
This work addresses the problem of human head pose estimation from single view images. 3D rigid head pose is estimated combining Active Appearance Models (AAM) with Pose from Orthography and Scaling with ITerations (POSIT). AAM shape landmarks are tracked over time and used in POSIT for pose estimation.

A Survey on Human Pose Estimation

Intelligent Automation & Soft Computing, 2015
Human pose estimation has attracted widespread attention due to its important application value and theoretical significance. A systemic survey of human pose estimation would be very meaningful.

Robust Optimal Pose Estimation

2008
We study the problem of estimating the position and orientationof a calibrated camera from an image of a known scene. A commonproblem in camera pose estimation is the existence of falsecorrespondences between image features and modeled 3D points.Existing techniques such as RANSAC to handle outliers have noguarantee of optimality.

Pose estimation of jointed structures

Proceedings. 1991 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2002
A framework is proposed for model-based monocular vision covering not only conventional 3-D rigid models, but also flexible structures made up of 3-D rigid bodies connected by rotational joints. Pose-estimation problems from a single view are defined and discussed according to this object model composed of rigid bodies and rotational axes, respectively

Nearly Analytical Pose Estimation

Proceedings 2007 IEEE International Conference on Robotics and Automation, 2007
This paper develops a new, nearly analytical method for pose estimation. Two steps are required: (1) solution of a least squares matrix problem, followed by projection of the solution onto the nearest scaled subunitary matrix, and (2) solution of a least squares vector problem, followed by projection onto the three dimensional special orthogonal group,
