Two-View Orthographic Epipolar Geometry: Minimal and Optimal Solvers
Journal of Mathematical Imaging and Vision, 2018 We will in this paper present methods and algorithms for estimating two-view geometry based on an orthographic camera model. We use a previously neglected nonlinear criterion on rigidity to estimate the calibrated essential matrix.

Revisiting Minimal Solver of Camera Triplets for Incremental Structure‐from‐Motion
The Photogrammetric Record, Volume 41, Issue 193, January–March 2026.Left: Overview of T2vP, a minimal solver for camera pose estimation requiring as few as six pure 2D correspondences, without relying on three‐view overlap. Right: T2vP successfully registers cameras in challenging scenarios where PnP solvers fail, as three‐view points are insufficient due to large viewing angle discrepancies.

Journal of Engineering, Volume 2026, Issue 1, 2026.Simultaneous localization and mapping (SLAM) plays a vital role in the operation of autonomous robots. In a dynamic environment, the results of some commonly used SLAM algorithms may not be optimal. Therefore, Visual SLAM is used. This study presents a comparative study of SLAM algorithms for autonomous mobile robots in structured indoor environments ...

Visual SLAM based on semantic information and geometric constraints in dynamic environment
智能科学与技术学报, 2023 Most existing visual SLAM systems assume that the external environment is static, ignoring the influence of dynamic objects on the SLAM system. This assumption largely affects the accuracy and robustness of autonomous navigation. To address this issue, a

Learning epipolar geometry from image sequences
2003 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2003. Proceedings., 2003 We wish to determine the epipolar geometry of a stereo camera pair from image measurements alone. This paper describes a solution to this problem, which does not require a parametric model of the camera system, and consequently applies equally well to a wide class of stereo configurations.
