This paper describes a method to recognize obstacles on the lunar or planetary surface for landers. The proposed method smoothes an image and uses a second moment of the gray-level image data for estimating high obstacles and rough terrains. The definition of safety for the lander depends on the height of obstacles. This paper proposes this method and the relation between the height of obstacles and the second moment. The simulation results of the proposed method are shown. The effectiveness of the proposed method is also discussed.","subitem_description_type":"Abstract"}]},"item_7_select_21":{"attribute_name":"学位","attribute_value_mlt":[{"subitem_select_item":"master"}]},"item_7_subject_13":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"548","subitem_subject_scheme":"NDC"}]},"item_7_text_24":{"attribute_name":"研究科・専攻","attribute_value_mlt":[{"subitem_text_value":"工学系研究科電子工学専攻"}]},"item_7_text_27":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_text_value":"修第号"}]},"item_7_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院工学系研究科 電子工学専攻"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田村, 嘉章"}],"nameIdentifiers":[{"nameIdentifier":"5643","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-05-31"}],"displaytype":"detail","filename":"tamura.pdf","filesize":[{"value":"9.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"tamura.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/1831/files/tamura.pdf"},"version_id":"d3ac0313-7a9b-4321-bad3-54be836b078e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"landing","subitem_subject_scheme":"Other"},{"subitem_subject":"image","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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"画像を用いた月惑星表面への着陸航法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"画像を用いた月惑星表面への着陸航法"}]},"item_type_id":"7","owner":"1","path":["234","261"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-08-08"},"publish_date":"2011-08-08","publish_status":"0","recid":"1831","relation_version_is_last":true,"title":["画像を用いた月惑星表面への着陸航法"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:43:15.046310+00:00"}
