Title (EN) RIGIDITY MEASUREMENT DEVICE AND RIGIDITY MEASUREMENT METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE MESURE DE RIGIDITÉ
(JA) 剛性測定装置および剛性測定方法
Abstract:
(EN) A rigidity measurement device (200) for measuring the rigidity of a measurement object is provided with a load estimation unit (240), a displacement calculation unit (230), and a rigidity calculation unit (250). The load estimation unit (240) estimates a load exerted on a measurement point set on the measurement object using a captured image of the measurement object. The displacement calculation unit (230) calculates a displacement of the measurement point using the captured image. The rigidity calculation unit (250) calculates the rigidity of the measurement object using the load and the displacement.
(FR) La présente invention concerne un dispositif de mesure de rigidité (200) permettant de mesurer la rigidité d'un objet à mesurer, le dispositif étant pourvu d'une unité d'estimation de charge (240), d'une unité de calcul de déplacement (230) et d'une unité de calcul de rigidité (250). L'unité d'estimation de charge (240) estime une charge exercée sur un point de mesure défini sur l'objet à mesurer à l'aide d'une image capturée de l'objet à mesurer. L'unité de calcul de déplacement (230) calcule un déplacement du point de mesure à l'aide de l'image capturée. L'unité de calcul de rigidité (250) calcule la rigidité de l'objet à mesurer à l'aide de la charge et du déplacement.
(JA) 剛性測定装置(200)は、計測対象の剛性を測定する剛性測定装置であって、荷重推定部(240)と、変位算出部(230)と、剛性算出部(250)とを備える。荷重推定部(240)は、計測対象が撮像された撮像画像を用いて、計測対象に設定された計測点に加わる荷重を推定する。変位算出部(230)は、撮像画像を用いて、計測点の変位を算出する。剛性算出部(250)は、荷重と変位とを用いて、計測対象の剛性を算出する。
