DEVICE AND METHOD FOR MEASURING MECHANICAL IMPEDANCE OF FLEXIBLE DEFORMABLE OBJECT

摘要

PROBLEM TO BE SOLVED: To provide a device and method capable of determining a mechanical impedance of a flexible deformable object without using various sensors.;SOLUTION: Since a high speed camera 40 as a photographing means for acquiring images before and after deformation of the flexible deformable object 100 is provided, the mechanical impedance such as rigidness, viscosity or elasticity of the flexible deformable object 100 can be determined without using sensors, by determining its displacement and by using an equation of motion of a known object (rigid body 30) which is a displacement applicator. Consequently, stable and highly-accurate measurement can be performed without requiring as hitherto much labor in order to clear problems such as calibration accuracy of various sensors, synchronization of a measuring signal, or noises.;COPYRIGHT: (C)2008,JPO&INPIT
