Application of ground penetrating radar imaging technology in expressway roadbed inspection
In order to realize the accurate detection of highway subgrade,this paper firstly uses mean filtering and principal component analysis to pre-process the radar image,then uses the spectrum residual method to extract the interest region of the image,and tracks the ground level information based on Markov algorithm.The results show that the recognition accuracy of the improved GPR is significantly improved compared with manual recognition,and the horizon tracking technology can accurately track the location of the disease.The research improves the detection accuracy of GPR imaging technology,and can provide technical reference and support for ensuring the safety and stability of roads.
