Title:
MEASUREMENT SYSTEM, CORRECTION PROCESSING DEVICE, CORRECTION PROCESSING METHOD, AND COMPUTER READABLE RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/097577
Kind Code:
A1
Abstract:
A measurement system 100 comprises: a measuring device 20 that measures the vibration of an object 40; an imaging device 30 disposed so as to be able to capture an image of the measuring device 20; and a correction processing device 10. The correction processing device 10 comprises a displacement calculation unit 11 that calculates the displacement of the measuring device 20 from time-series images of the measuring device 20 outputted by the imaging device 30; a movement amount calculation unit 12 that, on the basis of the displacement, calculates the amount of movement of the measuring device 20 with the imaging device 30 as a reference; and a correction processing unit 13 that corrects the vibration of the object as measured by the measuring device 20, using the calculated movement amount of the measuring device 20.
