However,worn pipes have been increased and a number of subsidences of a ground caused by the collapse wereoccurred. Recently, the inspection of the pipe is executed by the moving cart with CCD camera. Currently human inspector judges the condition of the pipe by the images recorded by the CCD camera. It should be noted that the judgment by the human causes the individual variation since it depends on the person's sense. Quantitative measurement is required.\nIn this paper, the 3D quantitative measurement system for a sewer pipe is introduced. Two parallel laser sheets are projected from the inside of the pipe and the two circular laser streaks appeared\non the inside surface of the pipe are recorded by the CCD. The measurement of the crosssection is established by analyzing the recorded streaks. Amount of displacement between two circular streaks are used to detect the tilt of the system against the axis of the pipe. The pipe is reconstructed by stacking of the crosssections\non considering the moved distance and the tilt of the robot. The automatic calibration using a liquid crystal display is also introduced in this paper. The calibration\nmethod reduces the lens distortion of a wide-angle lens and a high accurate measurement is\nestablished. Experimental result shows the feasibility of the system.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本機械学会","subitem_publisher_language":"ja"},{"subitem_publisher":"The Japan Society of Mechanical Engineers","subitem_publisher_language":"en"}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00187463","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03875024","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"川末, 紀功仁","creatorNameLang":"ja"},{"creatorName":"Kawasue, Kikuhito","creatorNameLang":"en"},{"creatorName":"川末, 紀久仁","creatorNameLang":"ja"},{"creatorName":"カワスエ, キクヒト","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{},{}],"givenNames":[{},{},{},{}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"酒井, 将司","creatorNameLang":"ja"},{"creatorName":"サカイ, ショウジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"脇山, 輝史","creatorNameLang":"ja"},{"creatorName":"ワキヤマ, テルフミ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大山, 茂樹","creatorNameLang":"ja"},{"creatorName":"オオヤマ, シゲキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"千田, 尚","creatorNameLang":"ja"},{"creatorName":"センダ, ヒサシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SAKAI, Shoji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"WAKIYAMA, Terufumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OHYAMA, Shigeki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SENDA, Hisashi","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":"2020-06-21"}],"displaytype":"detail","filename":"kawasue_kikaironbunsyu737_2008.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kawasue kikaironbunsyu737 2008.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/885/files/kawasue_kikaironbunsyu737_2008.pdf"},"version_id":"2bfbe722-5d54-44e5-bd77-c8d92f5a8096"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Sewer, Pipe measurement, Image processing, Laser, Calibration, 3 Dimensional","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"2平行レーザシートの投光による下水管形状計測ロボット","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2平行レーザシートの投光による下水管形状計測ロボット","subitem_title_language":"ja"},{"subitem_title":"Sewer Pipe Measurement Robot Using Parallel Laser Sheets","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"5","path":["73","27"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-06-23"},"publish_date":"2008-06-23","publish_status":"0","recid":"885","relation_version_is_last":true,"title":["2平行レーザシートの投光による下水管形状計測ロボット"],"weko_creator_id":"5","weko_shared_id":2},"updated":"2023-09-02T12:57:01.592637+00:00"}
