Background
The traffic sign plays an important role in providing road information and guaranteeing traffic safety in roads, and the foundation of the traffic sign generally adopts a reinforced concrete independent foundation. The surface of the foundation top surface is uneven due to construction and other factors, so that the phenomenon that the mark inclines in the installation process is caused, and potential safety hazards are caused to road driving. Therefore, after the construction of the mark foundation is completed, the flatness of the top surface of the mark foundation needs to be detected.
According to relevant specifications, a ruler measuring mode is adopted for detecting the flatness of the top surface of the mark foundation. The operation method comprises the following steps: the maximum gap is measured on the diagonal, and two points are measured on each basis. In the traditional technology, the flatness of the top surface of the foundation is generally detected by diagonally drawing lines by two detection personnel and measuring the maximum gap by one person by using a ruler. The method is time-consuming and labor-consuming, the position of the maximum clearance point cannot be well controlled, and the influence of human factors is large, so that the measurement result has errors.
