In this study, to evaluate the applicability of VDMS(Vision-based Displacement Measurement System) in the field, 30m of real specimens were measured vertical displacement using the VDMS and a displacement Transducer. The VDMS was to take a picture by attaching Target on the structure. Then, by analyzing the video in Digital Image correlation algorithm obtained a displacement of the structure. The vertical displacement of 30m real specimens using the VDMS and a displacement Transducer was very similar, and it is determined that the VDMS has a high applicability in the field.
