As the basis for reconstructing 3-D objects, a new method for identifying edges in images is presented. This method consists of the following three subprocedures: (1) differences of brightness of two subsequent pixels are calculated and binary images are made; (2) noise included in those image data is roughly eliminated by utilizing the properties of an edge in such images; and (3) noise not recognized in the previous subprocedure is eliminated by the relation between 3-D objects in 3-D space and images, by using multi image data obtained by a camera moving on a rail. An experimental camera system has been constructed in order to confirm the theoretical consideration, and various examples have been tested. The results show that almost all noise can be recognized and eliminated.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0001574000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-1354","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"山梨大学"},{"subitem_text_value":"航空宇宙技術研究所 数理解析部"},{"subitem_text_value":"航空宇宙技術研究所 数理解析部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Yamanashi University"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Computational Sciences Division"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Computational Sciences Division"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"古川, 進"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"磯部, 俊夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"本間, 幸造"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Furukawa, Susumu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Isobe, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Honma, Kozo","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-27"}],"displaytype":"detail","filename":"naltr0001354.pdf","filesize":[{"value":"362.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr0001354.pdf","url":"https://jaxa.repo.nii.ac.jp/record/40244/files/naltr0001354.pdf"},"version_id":"892b09c5-a34d-4369-acd0-0e9225df16b3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"コンピュータ画像","subitem_subject_scheme":"Other"},{"subitem_subject":"画像処理","subitem_subject_scheme":"Other"},{"subitem_subject":"ノイズ除去","subitem_subject_scheme":"Other"},{"subitem_subject":"3次元立体","subitem_subject_scheme":"Other"},{"subitem_subject":"復元処理","subitem_subject_scheme":"Other"},{"subitem_subject":"ステレオ画像","subitem_subject_scheme":"Other"},{"subitem_subject":"稜線検出","subitem_subject_scheme":"Other"},{"subitem_subject":"環境認識","subitem_subject_scheme":"Other"},{"subitem_subject":"computer vision","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"image processing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"noize elimination","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"three dimensional object","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"reconstruction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stereo vision","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"edge detection","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"environment recognition","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"ステレオ画像からの3次元立体復元のためのノイズ除去","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ステレオ画像からの3次元立体復元のためのノイズ除去"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"40244","relation_version_is_last":true,"title":["ステレオ画像からの3次元立体復元のためのノイズ除去"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T19:16:26.703765+00:00"}
