3 次元位置情報の推定が必要である．ブドウ房が多くぶら下がった屋外の棚状ブドウ圃場での深度センサーの使用は困難で，動画によるブドウ果粒の 3 次元位置推定が望ましい．撮影の利便性のため，画角の広い全方位カメラの使用が望まれる．また，ブドウ果粒は表面がテクスチャレスで形状の対称性が高く，かつ密集している．そのため，局所特徴量のマッチングを使用した従来の 3 次元復元と深度推定が困難である．そこで本稿では，こうした実用上の制約に対応すべく，深層学習による全方位カメラの教師なし単眼深度推定手法とカメラ位置推定によるブドウ果粒の重心位置推定の手法を提案する．実験の結果，テクスチャレスで密集した球状物体であるブドウ果粒の 3 次元位置情報が推定できることを定性的に確認した．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","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":"2022-03-03","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"2022-CVIM-229"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":216936}
