Abstract:

With the rapid expansion of urban areas and the increasing use of electricity, the need for locating buried cables is becoming urgent. In this article, a novel method to locate underground cables based on ground penetrating radar (GPR) and Gaussian-process regression is proposed. First, the coordinate system of the detected area is conducted, and the input and output of locating buried cables are determined. The GPR is moved along the established parallel detection lines, and the hyperbolic signatures generated by buried cables are identified and fit, thus the positions and depths of some points on the cable could be derived. On the basis of the established coordinate system and the derived points on the cable, the clustering method and cable fitting algorithm based on Gaussian-process regression are proposed to find the most likely locations of the underground cables. Furthermore, the confidence intervals of the cables’ locations are also obtained. Both the position and depth noises are taken into account in our method, ensuring robustness in different environments and equipment. Experiments on real-world datasets are conducted, and the obtained results demonstrate the effectiveness of the proposed method.
