Geologically Constrained Method for Deep Buried Strip Channel Detection in Urban Streets

As the process of urbanisation continues to accelerate, once an accident occurs in an underground strip/pipeline in a city, it will be difficult to investigate the location of the fault, which will bring great inconvenience to the people. Therefore, the detection and methodological studies of underground targets in urban strips are of great importance. Domestic and foreign research on the use of thermal infrared imaging technology for urban underground channels/pipeline target detection methods, the methods used mainly rely on looking at infrared images taken at different times to find undergro und targets. However, working with big data samples can be ch allenging. This research focuses on shallow underground pipelines in cities that have specific features, the methods used mainly rely on looking at infrared images tak en at different times to find underground targets. However, wo rking with big data samples can be challenging. This research f ocuses on shallow underground pipelines in cities that have spe cific features, there are great limitations; The research object of the underground target detection method based on microwave-enhanced infrared imaging technology is the shallow buried metal underground target, using microwaves to pass through the surface layer of the ground to act on the buried metal target, the target is heated due to microwave irradiation, and then through the infrared thermal imaging system detection, it is difficult to be applied to other non-metallic types of detection of underground targets, and the need for microwave emission source, unable to achieve long-distance, wide-range and passive detection. This paper proposes a geologically constrained infrared imaging detection method for deeply buried urban strip channels to solve the existing problems of weak thermal signals in infrared images of underground strip targets in the city after modulation by stratigraphic conduction, and the influence of different geological conditions in urban strata, which can not be accurately and effectively inverted to detect and locate the targets of underground strip channels in the city, so as to achieve the effective detection of deeply buried strip channels in the city streets.
