Underground Pipeline Extraction Method in Ground-Penetrating Radar Images Based on the Generalized Hough Transform
Xie Geng · 2013
To extract underground pipeline from Ground Penetrating Radar(GPR) images,a method was proposed by applying generalized Hough transform algorithm.According to the image features that the underground pipelines are the hyperbolic and have the certain width in pairs in image,the image is pretreated at first,and then the omnidirectional tracking method is used in edge tracking.Based on the hyperbolic feature model,the iterative calculation is carried out using the linear equations,and the description parameters of the hyperbola are determined.Then,the hyperbola in image is extracted.Experimental results indicated that the proposed approach was effective in extracting the underground pipeline and had robustness with varies conditions.
