"QRコードは二次元コードの一種で,小面積に印刷するだけで様々な媒体に情報を付加することができ,製造における発注システムなどで利用されている.しかし,カメラとQRコードが離れるほどQRコード画像は相対的に低解像度となるため,認識が困難になる.そこで本論文では,低解像度のQRコード画像の認識性能の向上を目的として,QRコードの特徴を利用した複数フレーム超解像手法を提案する.本手法では,QRコードの認識が検出とデコードの2段階の処理からなることを利用して,それぞれの精度向上を行うために2段階の超解像処理を導入する.また,QRコードが2値のグリッド状のパターンで構成されることを利用し,これを超解像処理の拘束として用いる.更に,全てのQRコードが共通してもつパターンを利用して,ぼけを表す点拡がり関数(PSF:Point Spread Function)の推定を行う.実動画像を利用した認識実験の結果,撮影動画像そのままでは認識できないほど低解像度のQRコード画像に対して,提案手法は高い認識率を示した.このことから,提案手法の有効性を確認した.", "subitem_description_language": "ja", "subitem_description_type": "Abstract"}]},
