Towards Rotation-only Imaging Geometry: Rotation Estimation
Xinrui Li, Qi Cai, Yuanxin Wu
Structure from Motion (SfM) is a critical task in computer vision, aiming to recover the 3D scene structure and camera motion from a sequence of 2D images. The recent pose-only ima…
Generic Calibration: Pose Ambiguity/Linear Solution and Parametric-hybrid Pipeline
Yuqi Han, Qi Cai, Yuanxin Wu
Offline camera calibration techniques typically employ parametric or generic camera models. Selecting parametric models relies heavily on user experience, and an inappropriate came…
Linear Relative Pose Estimation Founded on Pose-only Imaging Geometry
Qi Cai, Xinrui Li, Yuanxin Wu
How to efficiently and accurately handle image matching outliers is a critical issue in two-view relative estimation. The prevailing RANSAC method necessitates that the minimal poi…
A Pose-only Solution to Visual Reconstruction and Navigation
Qi Cai, Lilian Zhang, Yuanxin Wu +2
Visual navigation and three-dimensional (3D) scene reconstruction are essential for robotics to interact with the surrounding environment. Large-scale scenes and critical camera mo…
Segmenting Epipolar Line
Shengjie Li, Qi Cai, Yuanxin Wu
Identifying feature correspondence between two images is a fundamental procedure in three-dimensional computer vision. Usually the feature search space is confined by the epipolar…
