Automatic Identification of Underground Pipeline Based on Ground Penetrating Radar

Abstract

The underground pipelines of cities are complex and diverse, and they are responsible for important functions such as energy transportation and information transmission. In urban life and construction, it is necessary to grasp the location and depth of underground pipelines. Ground Penetrating Radar (GPR) is a real-time and efficient non-destructive detection technology. It has the advantages of fast detection speed, high resolution, easy operation and wide detection range. Therefore, it is the preferred method for urban underground pipeline detection. Based on the electromagnetic wave reflection mechanism of GPR detection underground pipeline, this paper proposes a new method of non-excavation and non-destructive on-site detection to identify underground pipe diameter, determine the position and radius of underground circular pipeline, and realize the automatic identification to underground pipeline.
