Document Type and Number:
Japanese Patent JP7152201
Kind Code:
B2
Abstract:
To inspect a seismic isolator efficiently with good accuracy.SOLUTION: An inspection system 10 inspects a seismic isolator 20 installed between an upper structure 60 and a lower structure 62. A camera 40 captures a plurality of images from different viewpoints that include a reference scale 30 having a known length and the seismic isolator 20. At this time, a plurality of images may be captured through a plurality of imaging operations using a monocular camera. The reference scale 30 uses a plate-like member 32 having, for example, two diagrams displayed the center-to-center distance of which is known. A dimension calculation unit 52 calculates the dimension of each part of the seismic isolator 20 on the basis of the plurality of images.SELECTED DRAWING: Figure 4
