Pose and Shape Reconstruction of a Noncooperative Spacecraft Using Camera and Range Measurements [PDF]
, 2017 Recent interest in on-orbit proximity operations has pushed towards the development of autonomous GNC strategies. In this sense, optical navigation enables a wide variety of possibilities as it can provide information not only about the kinematic state ...

Fast iterative five point relative pose estimation
2013 IEEE Workshop on Robot Vision (WORV), 2013 Robust estimation of the relative pose between two cameras is a fundamental part of Structure and Motion methods. For calibrated cameras, the five point method together with a robust estimator such as RANSAC gives the best result in most cases. The current state-of-the-art method for solving the relative pose problem from five points is due to Nister ...

Relative Pose Estimation Algorithm with Gyroscope Sensor [PDF]
Journal of Sensors, 2016 This paper proposes a novel vision and inertial fusion algorithm S2fM (Simplified Structure from Motion) for camera relative pose estimation. Different from current existing algorithms, our algorithm estimates rotation parameter and translation parameter separately.

Mixed marker-based/marker-less visual odometry system for mobile robots [PDF]
, 2013 When moving in generic indoor environments, robotic platforms generally rely solely on information provided by onboard sensors to determine their position and orientation. However, the lack of absolute references often leads to the introduction of severe

Multi-View Monocular Pose Estimation for Spacecraft Relative Navigation [PDF]
2018 AIAA Guidance, Navigation, and Control Conference, 2018 This paper presents a method of estimating the pose of a non-cooperative target for spacecraft rendezvous applications employing exclusively a monocular camera and a threedimensional model of the target. This model is used to build an offline database of prerendered keyframes with known poses.

Robot-to-robot relative pose estimation using humans as markers [PDF]
Autonomous Robots, 2021 In this paper, we propose a method to determine the 3D relative pose of pairs of communicating robots by using human pose-based key-points as correspondences. We adopt a 'leader-follower' framework, where at first, the leader robot visually detects and triangulates the key-points using the state-of-the-art pose detector named OpenPose.

IMAGE-BASED ORIENTATION DETERMINATION OF MOBILE SENSOR PLATFORMS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021 Estimating the pose of a mobile robotic platform is a challenging task, especially when the pose needs to be estimated in a global or local reference frame and when the estimation has to be performed while the platform is moving.

Accurate Covariance Estimation for Pose Data From Iterative Closest Point Algorithm
Navigation, 2023 One of the fundamental problems of robotics and navigation is the estimation of the relative pose of an external object with respect to the observer. A common method for computing the relative pose is the iterative closest point (ICP) algorithm, where a ...
