Certifiable relative pose estimation [PDF]
Image and Vision Computing, 2021 In this paper we present the first fast optimality certifier for the non-minimal version of the Relative Pose problem for calibrated cameras from epipolar constraints. The proposed certifier is based on Lagrangian duality and relies on a novel closed-form expression for dual points.

Globally Optimal Relative Pose Estimation with Gravity Prior [PDF]
2021 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2021 Smartphones, tablets and camera systems used, e.g., in cars and UAVs, are typically equipped with IMUs (inertial measurement units) that can measure the gravity vector accurately. Using this additional information, the $y$-axes of the cameras can be aligned, reducing their relative orientation to a single degree-of-freedom.

Line-based relative pose estimation [PDF]
CVPR 2011, 2011 We present an algorithm for calibrated camera relative pose estimation from lines. Given three lines with two of the lines parallel and orthogonal to the third we can compute the relative rotation between two images. We can also compute the relative translation from two intersection points.

Relative Pose Estimation For Stereo Rolling Shutter Cameras [PDF]
2020 IEEE International Conference on Image Processing (ICIP), 2020 In this paper, we present a novel linear algorithm to estimate the 6 DoF relative pose from consecutive frames of stereo rolling shutter (RS) cameras. Our method is derived based on the assumption that stereo cameras undergo motion with constant velocity around the center of the baseline, which needs 9 pairs of correspondences on both left and right ...

Monocular Pose Estimation of an Uncooperative Spacecraft Using Convexity Defect Features
Sensors, 2022 Spacecraft relative pose estimation for an uncooperative spacecraft is challenging because the target spacecraft neither provides sensor information to a chaser spacecraft nor contains markers that assist vision-based navigation.

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.

Accurate Line-Based Relative Pose Estimation With Camera Matrices
IEEE Access, 2020 While most monocular structure-from-motion frameworks rely on sparse keypoints, it has long been acknowledged that lines represent an alternative, higher-order feature with high accuracy, repeatability, and abundant availability in man-made environments.

Dynamical Pose Estimation with Graduated Non-Convexity for Outlier Robustness [PDF]
Modeling, Identification and Control, 2022 In this paper we develop a method for relative pose estimation for two sets of corresponding geometric primitives in 3D with a significant outlier fraction.
