Title:
PURE POSE SOLUTION METHOD AND SYSTEM FOR MULTI-VIEW CAMERA POSE AND SCENE
Document Type and Number:
WIPO Patent Application WO/2021/114434
Kind Code:
A1
Abstract:
Provided are a pure pose solution method and system for a multi-view camera pose and scene. The method comprises: a pure rotation abnormality recognition step, involving: performing pure rotation abnormality recognition on all views, marking views having a pure rotation abnormality, and obtaining marked views and non-marked views; a global translation linear calculation step, involving selecting one of the non-marked views as a reference view, constructing a constraint tr=0, constructing a global translation linear constraint, solving a global translation (I), recovering a global translation of the marked views according to tr and (I), and screening a correct solution of the global translation; and a three-dimensional scene analytical recovery step, involving: analyzing and recovering the coordinates of all 3D points according to a correct solution of a global pose. The calculation efficiency and robustness of multi-view camera pose and scene structure recovery can be greatly improved.
