Agentic Relative Camera Pose Estimation via Learned Ranking and Verification
Zhining Gu, Shangjie Du, Weimin Qiu +3
A wide range of approaches have been developed for camera pose estimation, including correspondence-based methods, end-to-end pose regression, and recent 3D geometric foundation mo…
Initialization-Free Bundle Adjustment Revisited: A Controlled Experimental Study
Simon Weber, Mateo de Mayo, Je Hyeong Hong +3
Initialization-free bundle adjustment (InitFree BA) aims to recover camera poses and scene structure directly from image observations, avoiding the geometric initialization stages…
Towards Initialization-free Calibrated Bundle Adjustment
Carl Olsson, Amanda Nilsson
A recent series of works has shown that initialization-free BA can be achieved using pseudo Object Space Error (pOSE) as a surrogate objective. The initial reconstruction-step opti…
Making Rotation Averaging Fast and Robust with Anisotropic Coordinate Descent
Yaroslava Lochman, Carl Olsson, Christopher Zach
Anisotropic rotation averaging has recently been explored as a natural extension of respective isotropic methods. In the anisotropic formulation, uncertainties of the estimated rel…
Certifiably Optimal Anisotropic Rotation Averaging
Carl Olsson, Yaroslava Lochman, Johan Malmport +1
Rotation averaging is a key subproblem in applications of computer vision and robotics. Many methods for solving this problem exist, and there are also several theoretical results…
