METHOD AND APPARATUS FOR REMOVING OUTLIERS FROM A MAIN VIEW OF A SCENE DURING 3D SCENE RECONSTRUCTION

摘要

A method and an apparatus (20) for removing outliers from a main view of a scene during 3D reconstruction of a scene from multiple views of the scene are described. A 3D projection unit (23) projects (10) a 3D point of a pixel of the main view into neighboring views. A comparator (24) then compares (11) the distance of each of the projected 3D points in the neighboring views to the 3D point of the main view with a defined distance threshold. Based on the comparison a flagging unit (25) assigns (12) flags to the pixel in the main view. Finally, depending on values of the flags a rejecting unit (26) rejects (13) the pixel in the main view as an outlier.
