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…
Visual-inertial state estimation based on Chebyshev polynomial optimization
Hongyu Zhang, Maoran Zhu, Qi Cai +1
This paper proposes an innovative state estimation method for visual-inertial fusion based on Chebyshev polynomial optimization. Specifically, the pose is modeled as a Chebyshev po…
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…
