High grade digital camera such as single lens reflex camera has over 10M pixel in a CCD. Then the accuracy of an angle measurement can achieves less than 1 second (1/3600 degree). This is almost the same specification with surveying equipment such as total station or transit. When stereo imageries are obtained, 3 dimensional measurement can be carried out base on co-linearity equation with ground control points. The ground control point means known 3 dimensional coordinates on the imagery. At least 4 ground control points are required to derive co-linearity equation. Moreover, lens distortion must be eliminated for accurate measurement. The elimination of the lens distortion is called lens calibration. Usually, the lens calibration is very difficult because many ground control points must be prepared. For easy lens calibration, the authors suggests a method using constellation pictures. Stars are accurately measured in this method. Starcatalogue has information of dimensional coordinates with some parameters. And the stars are too far from the earth. Then, the distance between the stars and the earth assumed infinite. Therefore, the position and attitude of camera in the constellation pictures also assumed center of celestial sphere. Computation of parameter of lens distortion will be very simple. After lens calibration, 3 dimensional measurement using digital camera can be carried out. Advantages of digital photogrammetry is high resolution 3 dimensional data can be obtained. The digital photogrammetry will be applied in some fields such as measurement of disaster site, an archive of surface model. This paper reports suggested method of lens calibration. Moreover, applications of digital photogrammetry are presented.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_36": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Society for Social Management Systems"}]}, "item_5_source_id_11": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2432-552X", "subitem_source_identifier_type": "ISSN"}]}, "item_5_version_type_19": {"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": [{"creatorNames": [{"creatorName": "Uda, Koji"}], "nameIdentifiers": [{"nameIdentifier": "2802", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Takagi, Masataka"}], "nameIdentifiers": [{"nameIdentifier": "2803", "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": "2019-02-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "SMS10-172.pdf", "filesize": [{"value": "414.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 414500.0, "url": {"label": "SMS10-172.pdf", "url": "https://kutarr.kochi-tech.ac.jp/record/1055/files/SMS10-172.pdf"}, "version_id": "7b866d61-e77e-4efc-9af8-bc94b7201ffb"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "lens calibration", "subitem_subject_scheme": "Other"}, {"subitem_subject": "digital photogrammetry", "subitem_subject_scheme": "Other"}, {"subitem_subject": "application", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "conference paper", "resourceuri": "http://purl.org/coar/resource_type/c_5794"}]}, "item_title": "Lens Calibration For Digital Photogrammetry And The Application", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Lens Calibration For Digital Photogrammetry And The Application"}]}, "item_type_id": "5", "owner": "2", "path": ["22"], "permalink_uri": "http://hdl.handle.net/10173/1850", "pubdate": {"attribute_name": "公開日", "attribute_value": "2018-02-06"}, "publish_date": "2018-02-06", "publish_status": "0", "recid": "1055", "relation": {}, "relation_version_is_last": true, "title": ["Lens Calibration For Digital Photogrammetry And The Application"], "weko_shared_id": -1}
