Research on the Application of VIC-3D Technology in Civil Engineering

Abstract

Digital image correlation method has been widely used in various research fields of civil engineering since it was proposed, because of its convenient and simple, full-field measurement, good environmental adaptability and other characteristics. It has become an important measurement method in various research fields. The CCD camera is used to match the position of the same pixel in the two speckle images before and after the surface deformation of the specimen to obtain the displacement vector of the pixel, and record the change of the speckle characteristics of the specimen surface. Combined with computer vision and digital image processing technology, the physical quantities such as the morphology, displacement and strain of the object surface can be accurately measured. Therefore, this paper introduces the application of VIC-3D technology in civil engineering in detail.
