Relative Pose Estimation of Unmanned Aerial Systems

2018 26th Mediterranean Conference on Control and Automation (MED), 2018
The relative accurate pose estimation problem of collaborating Unmanned Aerial Systems (UASs) in GPS-denied environments is addressed in this article. The on-board system uses fiducial markers attached in the facets of a truncated rhombicuboctahedron placed on top of the UAS.

Fuzzy relative positions for qualitative pose estimation

Proceedings 15th International Conference on Pattern Recognition. ICPR-2000, 2002
Similarity of object part embedding (description of how each part is surrounded by its neighbors) can be used to qualitatively infer similarity of images. We present an approach using fuzzy relative positions to qualitatively describe and reason with object part embedding.

An efficient solution to the relative pose estimation with a common direction

2020 IEEE International Conference on Robotics and Automation (ICRA), 2020
In this paper, we propose an efficient solution to the calibrated camera motion estimation with a common direction. This case is relevant to smart phones, tablets, and other camera-IMU (Inertial measurement unit) systems, which have accelerometers to measure the gravity direction. We can align one of the axes of the camera with this common direction so

Robust relative pose estimation with integrated cheirality constraint

2008 19th International Conference on Pattern Recognition, 2008
The cheirality constraint, which requires that reconstructed point correspondences lie in front of the cameras, has not typically been integrated into traditional RANSAC-based pose estimators. We have developed a new RANSAC-based relative pose estimator which incorporates the cheirality constraint not only to preempt invalid epipolar geometry ...

Relative Pose Estimation from Two Circles

2008
Motion estimation between two views especially from a minimal set of features is a central problem in computer vision. Although algorithms for computing the motion between two calibrated cameras using point features exist, there is up to now no solution for a scenario employing just circles in space.

Relative pose estimation from points by Kalman filters

2015 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2015
This paper addresses a method of dynamically estimating relative pose between two rigid bodies from four corresponding point sets during motion in applications such as visual servoing and metrology for intelligent manufacturing. Instead of tracking each body individually relative to a camera, the underlying problem is how to track two bodies ...

RPE-PAD: Relative Pose Estimation for Pose-agnostic Anomaly Detection

Proceedings of the AAAI Conference on Artificial Intelligence
Pose-agnostic Anomaly Detection (PAD) aims to detect anomalies when the poses of query images are unknown and differ from those in the training set. Therefore, accurately estimating the camera poses for the query images in the test set is critical for this task. Existing query-specific framework methods require re-optimizing a new set of parameters for

Relative Pose Estimation for Planetary Entry Descent Landing

2011
The paper is about the estimation of the relative position of a spacecraft, during the Entry Descent Landing (EDL) phase, by means of computer vision. A camera installed on board of the vehicle acquires images that are used for estimating the relative position of the camera between two consecutive images.
