Title:
MEASUREMENT SYSTEM, CORRECTION PROCESSING DEVICE, CORRECTION PROCESSING METHOD AND COMPUTER-READABLE RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/097576
Kind Code:
A1
Abstract:
This measurement system 100 is provided with: a measurement device 20 which measures a vibration of an object 40; an image capturing device 30 which is fixed to the measurement device 20 so as to be able to capture an image of a preset reference surface 50; and a correction processing device 10. The correction processing device 10 is provided with: a displacement calculation unit 11 which calculates the displacement of the reference surface 50 from time-series images of the reference surface 50; a movement amount calculation unit 12 which calculates a movement amount of the measurement device 30 with respect to the reference surface 50 on the basis of the calculated displacement and preset image capturing information of the image capturing device 30; and a correction processing unit 130 which corrects the vibration measured by the measurement device 20 to a vibration based on the reference surface 50 by using the calculated movement amount.
