Abstract

Abstract: As an important hidden danger of urban safety,urban road diseases has the characteristics of concealment and sudden,which needs to be detected and treated in time. Ground penetrating radar uses electromagnetic wave reflection to determine the distribution of underground media. It is widely used in urban road disease detection because of its nondestructive,fast and shallow high-resolution advantages. However,if the disease body needs to be further treated,it needs to be further carefully surveyed. This paper combines the advantages of ground penetrating radar in road disease detection with the real-time video and measurement function of three-dimensional measuring endoscope technology to realize the accurate positioning and accurate measurement of road underground disease body,so as to provide useful data for subsequent prevention and treatment.

Key words: ground penetrating radar(GPR), 3D measuring endoscope(TDE), road disease body, cavity, spectrum
