Structural deformation monitoring system

摘要

PROBLEM TO BE SOLVED: To provide a simple low-cost structure displacement monitoring system.SOLUTION: A structure displacement monitoring system photographs a region including one or a plurality of indicators 18A of a known shape fixed onto a member 3C constituting a structure 12 and includes: imaging means 14A for acquiring a photographed image; image analysis means 26 for performing image analysis processing of an image acquired by the imaging means 14A to obtain a position and a shape of an indicator included in the image; and deformation volume measuring means 28 for measuring deformation volume of the member 3C on the basis of the position and shape of the indicator 18A obtained by the image analysis means 26.SELECTED DRAWING: Figure 1
