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 ...

International Journal of Advanced Robotic Systems, 2022 Image moments are global descriptors of an image and can be used to achieve control-decoupling properties in visual servoing. However, only a few methods completely decouple the control.

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 ...

XNect: Real-time Multi-Person 3D Motion Capture with a Single RGB Camera
, 2020 We present a real-time approach for multi-person 3D motion capture at over 30 fps using a single RGB camera. It operates successfully in generic scenes which may contain occlusions by objects and by other people. Our method operates in subsequent stages.

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.

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.

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

Human Pose Estimation using Deep Consensus Voting
, 2016 In this paper we consider the problem of human pose estimation from a single still image. We propose a novel approach where each location in the image votes for the position of each keypoint using a convolutional neural net.
