Deeper Understanding on Solution Ambiguity in 3D Motion Parameters Estimation by Homography Decompositionenghttp://id.nii.ac.jp/1001/00077757/Conference Paperhttps://ipsj.ixsq.nii.ac.jp/ej/?action=repository_action_common_download&item_id=77757&item_no=1&attribute_id=1&file_no=1Copyright (c) 2011 by the Information Processing Society of JapanDept. of Information Science, University of FukuiDept. of Information Science, University of FukuiDept. of Information Science, University of FukuiHeLiuHiroyukiHaseShogoTokaiThis paper discusses two dependencies of the solution ambiguity problem on 3D motion parameter estimation by homography decomposition. By considering the geometrical and the algebraic relations of the planar object before and after the 3D motion, we found the solution ambiguity is not inevitably. It depends on two kinds of factors: (1) for the same 3D motion, it depends on the size of the object; (2) for the same object size, it depends on the 3D motion parameters. In this paper, we also present a criterion to determine the condition which can obtain the unique solution. It is much more reliable than previous discussions.画像の認識・理解シンポジウム(MIRU2011)論文集20118148172011-07-202011-09-29
