Abstract—There are two types of devices, contact and noncontact sensor, for measuring the displacement of a building during construction. The contact sensors are not easy to set up but relatively cheap. On the other hands, the non-contact sensors are easy to install but expensive. In order to consider the economic aspect, the displacement measurement technique using the image base is emerging. In this paper, displacement of steel pipe support was measured by using displacement gauges and image processing technique with pattern. Based on the experiment, the load-displacement curves and the mean error were compared and evaluated with the results of image processing. This study investigates the possibility of replacing the existing displacement gauges with image processing technology.
