RA-L 2026

In this paper, we aim to estimate the relative pose and focal length between two views with known intrinsic parameters except for an unknown focal length from two affine correspondences (ACs). Cameras are commonly used in combination with inertial measurement units (IMUs) in applications such as sel

Camera Calibration using a Collimator System

Shunkun Liang, Banglei Guan*, Zhenbao Yu, Pengju Sun, Yang Shang

ECCV 2024oral

"Camera calibration is a crucial step in photogrammetry and 3D vision applications. In practical scenarios with a long working distance to cover a wide area, target-based calibration methods become complicated and inflexible due to site limitations. This paper introduces a novel camera calibration m…
