SLAM （Simultaneous Localization and Mapping）処理が必要とされる．SLAM は主にトラッキング，ローカルマッピング，ループグロージングの 3 つの処理から構成される．このうちローカルマッピングは，実行コストが大きい一方，疎行列やグラフ構造などを扱うことから効率の良い並列化が難しい．そのため本稿では，オープンソースの SLAM 実装である ORB-SLAM3 を対象として，データ構造の特徴を生かした並列化方法を提案する．またトラッキングの特徴点抽出処理も合わせて並列化した場合，発生する多くのスレッドができるだけ同一コアで競合しないような割り当て手法を報 告する．これらの提案手法を適用して両処理を並列化したところ，Intel サーバ上ではトラッキングで 1.40 倍，ローカルマッピングで 1.35 倍の速度向上が同時に得られた．また，NVIDIA Jetson 上でも，トラッキングで 1.22 倍，ローカルマッピングで 1.26 倍の速度向上が得られ，提案手法がコア数の少ない組込み環境にも有効であることが確認できた．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システムとLSIの設計技術（SLDM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-03-03","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"40","bibliographicVolumeNumber":"2022-SLDM-198"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":217194,"updated":"2025-01-19T15:35:17.788363+00:00","links":{},"created":"2025-01-19T01:17:41.915678+00:00"}
