Title:
STATUS DETERMINATION DEVICE AND STATUS DETERMINATION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/047093
Kind Code:
A1
Abstract:
The present invention addresses the problem of making it possible to distinguish and detect cracking, peeling, internal cavities, and other defects through the remote observation of a structure. A status determination device according to the present invention is provided with a displacement calculation unit for calculating a two-dimensional spatial distribution of the displacement of a structure surface from time series images of the structure surface before and after load application and an abnormality determination unit for identifying flaws in the structure on the basis of a comparison of the two-dimensional spatial distribution and an already provided spatial distribution of displacement.
