Title:
RIGIDITY MEASUREMENT DEVICE AND RIGIDITY MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2018/138943
Kind Code:
A1
Abstract:
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.
