Robust Relative Rotation Averaging. - Abstract - Europe PMC

WebRotation averaging appears as a subproblem in many important applications in computer vision, robotics, sen- sor networks and related areas. Given a number of rela- tive rotation estimates between pairs of poses, the goal is to compute absolute camera orientations with respect to some common coordinate system. WebUnlike the traditional rotation averaging methods which estimate all the absolute rotations simultaneously and focus on designing either robust loss function or outlier filtering strategy, here the absolute rotations are estimated in an incremental way. gnu octave bitwise operationsWebApr 12, 2024 · This paper addresses the problem of robust and efficient relative rotation averaging in the context of large-scale Structure from Motion.
