Abstract:
(EN) According to the present invention: images of a plurality of tires that differ from one another in either one or both of the type and the tire condition thereof are acquired and are used as teacher images; the teacher images are converted to a size having a fixed number of pixels, after which a plurality of sets of converted teacher image data are used as learning images, which are learned using a convolutional neural network to set parameters of the network; thereafter, a tire image of a tire to be recognized is acquired, is converted to the same size as the teacher images and is input into the convolutional neural network to assess either one or both of the type and the tire condition of the target tire.
(FR) Selon la présente invention : des images d'une pluralité de pneus qui diffèrent les uns des autres par leur type et/ou l'état du pneu sont acquises et sont utilisées en tant qu'images d'enseignant ; les images d'enseignant sont converties en une taille présentant un nombre fixe de pixels, puis une pluralité d'ensembles de données d'images d'enseignant converties sont utilisés en tant qu'images d'apprentissage, ces dernières étant apprises à l'aide d'un réseau neuronal convolutionnel afin d'établir des paramètres du réseau ; ensuite, une image de pneu d'un pneu à reconnaître est acquise, est convertie en la même taille que les images d'enseignant et est entrée dans le réseau neuronal convolutionnel afin d'évaluer le type et/ou l'état de pneu du pneu cible.
(JA) 品種もしくはタイヤ状態のいずれか一方もしくは両方の異なる複数のタイヤ画像を取得して、これを教師用画像とし、これらの教師用画像を一定の画素数のサイズへ変換した後、変換した複数の教師用画像データを学習用画像として、畳み込みニューラルネットワークで学習してネットワークのパラメータを設定し、しかる後に、認識対象のタイヤのタイヤ画像を取得し、これを教師用画像と同じサイズへ変換してから畳み込みニューラルネットワークに入力して、対象となるタイヤの品種もしくはタイヤ状態のいずれか一方もしくは両方を判別するようにした。
