SYSTEM FOR MEASURING ABSOLUTE DISPLACEMENT OF STRUCTURE

摘要

PURPOSE: An absolute displacement measuring system of a structure is provided to improve accuracy of absolute displacement measurement by dividing displacement into multiple sections. CONSTITUTION: An absolute displacement measuring system of a structure comprises a measurement section setting part(100), an image processing part(200), and a displacement calculating part(300). The measurement section setting part has an emitting unit and a photographing unit. The emitting unit emits light to an opposite direction of a sign. The photographing unit photographs an image of the radial direction of the emitting unit. The image processing part collects the image of the sign during the setting time. The displacement calculating part calculates absolute displacement by receiving the image.
