ABSTRACT
Various types of Segmental Retaining Wall (SRW) are widely used worldwide for land use in slope areas. Inspections are periodically performed on the retaining wall, and various studies have been conducted to analyze the behavior of the retaining wall according to load and rainfall. However, the collapse of SRW continues to occur, and most collapses of SRW are attributed to facing displacement and settlement caused by water pressure and earth pressure. In this study, the behavior of SRW was monitored from a single camera system consisting of monocular vision and feature matching considering various conditions such as noise and brightness in the image. Performances of image registration and behavior calculation were evaluated from the results of several experiments. Behavior measurement error in controlled conditions was distributed within 1.89mm, and RMSE and MRE were 1.22 mm and 3.68%, respectively.
