Study of displacement detection method of structures using image processing

Abstract

This paper investigates displacement detection methods using image processing in order to reduce the time and effort required to install displacement gauges when conducting durability and creep tests in the building field. Using a creep test of a door installed in a box-shaped frame as an example, the detection of structural displacement by image processing technology and the correction method of images using vectors for changes in the angle of view were investigated. The results suggest that displacement detection by image processing is useful in the field of architecture by applying image correction even when the angle of view changes.
