Ground Penetrating Radar (GPR) is widely used as a non-destructive approach
to estimate buried utilities. When the GPR's detecting direction is
perpendicular to a pipeline, a hyperbolic characteristic would be formed on the
GPR B-scan image. However, in real-world applications, the direction of
pipelines on the existing pipeline map could be inaccurate, and it is hard to
ensure the moving direction of GPR to be actually perpendicular to underground
pipelines. In this paper, a novel model is proposed to estimate …
