Among them, measuring the flatness of walls and floor slabs is an important part of the construction project management. The existing measuring device is usually composed of a ruler and a feeler gauge. The ruler is placed on the measuring surface, and then the maximum gap between the ruler and the measuring surface is found. The feeler gauge is inserted to read the data to determine whether the flatness is qualified. However, in actual use, due to the small size of the feeler gauge, which is usually a steel sheet or a plastic sheet, it is often lost or damaged.
