[0002] A building structure is a skeleton structure formed by building components such as plates, beams, columns, walls, and foundations. It has certain spatial functions and can safely withstand various normal loads of the building. Once cracks appear in the building structure, it is likely to cause insufficient bearing capacity of the building structure or components and cause damage. At the same time, if the cracks are not detected and treated, they will continue to develop, thus affecting the safety of the building structure. Workers generally use detectors to detect cracks on the wall. The main principle is to use modern electronic imaging technology to image the original appearance of the cracks in the structure being tested on the host display screen, and read the true and reliable crack width data through the high-precision laser scale on the screen.
