In our approach, PPFD can be measured by calculating spectral irradiance of daylight which fluctuates hour by hour according to weather condition changes, from the color information of a reference object in an image captured by a camera. PPFD at different points can be simultaneously measured by capturing reference objects which are set in a plant community. In the experiments, we confirmed that the proposed method can achieve high performance which is equivalent to quantum sensors on the market.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"4","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータビジョンとイメージメディア（CVIM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2014-02-24","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"29","bibliographicVolumeNumber":"2014-CVIM-191"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":98595,"updated":"2025-01-21T12:24:48.975591+00:00","links":{},"created":"2025-01-18T23:44:48.733627+00:00"}
