In recent years, with the increasing development and utilization intensity of urban underground space, phenomena such as underground water and soil loss and erosion of roads are caused by the factors such as repeated road excavation, damage and leakage of underground pipe networks, road surface load change, foundation pit construction disturbance and the like, so that diseases such as cavities are formed, and finally, road collapse accidents are frequently caused. Therefore, the method for detecting the hidden danger of the urban road collapse is usually developed in advance to avoid the occurrence of road accidents. In the prior art, a ground penetrating radar method is generally adopted, but the ground penetrating radar method is often dependent on engineering experience of technicians to process and interpret, and has the problems of low accuracy of obtained results and low working efficiency.
In view of the above, the embodiment of the application provides a method for detecting urban road underground shallow diseases, which is based on a cloud server, and can effectively improve the accuracy of detection results by combining a geological radar detection technology and an artificial intelligent image recognition technology.

s101, generating radar map data according to radar images acquired by the three-dimensional geological radar and positioning data acquired by the positioning equipment.
The working principle of the three-dimensional geological radar is that high-frequency pulse electromagnetic waves are emitted to an underground medium, and the high-frequency pulse electromagnetic waves are used for determining the distribution condition of the underground medium. Specifically, based on the electrical difference of the underground medium, the three-dimensional geological radar can emit high-frequency pulse electromagnetic waves through one antenna, and the other antenna receives electromagnetic wave signals reflected by the underground medium and analyzes and interprets the received electromagnetic wave signals to obtain radar images.
In the specific implementation, electromagnetic waves propagating in an underground medium encounter media with different dielectric constants or are reflected by a measured object body to form different electromagnetic wave propagation paths and waveform information, so that the three-dimensional geological radar can analyze the spatial position of the underground object body or interface according to the information such as the propagation time, waveform, amplitude and the like in a received electromagnetic wave signal, and further a corresponding radar image can be obtained.
Optionally, the radar image is a cross-sectional view of the subsurface shallow layer obtained through processing analysis. If there is a disease or an abnormal body in the underground medium, the difference in dielectric constant between the two sides of the interface of the disease or abnormal body is large, and a strong reflection signal is generated, so that the position of the disease or abnormal body can be determined from the time section of the section.
On the other hand, the positioning device can be used for precisely determining the three-dimensional coordinates of the three-dimensional geological radar antenna, and meanwhile, acquiring the measurement time of the corresponding measuring point to serve as corresponding positioning data.
When the radar image is acquired, the geographic position of the road is acquired through the positioning equipment, so that the mapping relation of the road position is formed, and the association relation between the radar image and the positioning data can be determined. If diseases or abnormal bodies exist in the underground medium, corresponding positioning data can be searched according to the association relation.
It should be noted that, the embodiment of the present application may also collect data according to two-dimensional geological radar, which is not limited herein. In addition, the positioning device according to the embodiment of the present application may be based on a global positioning system (Global Positioning System, abbreviated as GPS) positioning technology, or may be a beidou satellite navigation system in china, a galileo satellite navigation system in the european union, a russian global navigation satellite system, or the like, which is not limited herein.

The marked disease types can comprise non-disease, cavity, void, water-rich, general loose, serious loose and the like.
Optionally, the training sample set is subjected to an augmentation operation, and the augmented training sample set is divided into a training set, a verification set and a test set according to a certain proportion, wherein the specific proportion value is set according to an actual application scene, and the method is not limited. The method can further expand the database in subsequent application, enrich the training sample set and improve the accuracy of the intelligent recognition algorithm.

It should be noted that YOLO is a classical single-stage object detection algorithm, which converts the object detection problem into a regression problem of middle boundary separation in space, and the processing speed of YOLO based on object detection is very fast, and the recognition degree of background and object is very high. YOLOv5 is the latest series of YOLOv, and the embodiment of the application takes the model structure of YOLOv5 as a main reference, on one hand, because the model structure of YOLOv5 has better results, the accuracy of the overall results is more ensured; on the other hand, the model is lighter, meets the requirements of practical application and training research of the embodiment of the application, and is convenient for the deployment of the model on a cloud server and the implementation of detection tasks.
Optionally, the training sample set is brought into a preset neural network algorithm to carry out parameter adjustment, so that the disease identification model is obtained through training.
After the disease recognition model is obtained, the disease recognition model can be tested and verified by the test set and the verification set, and if the disease recognition model is unqualified, the disease recognition model can be further adjusted by training until the disease recognition model is qualified.
In the embodiment, radar map data are generated according to radar images acquired by the three-dimensional geological radar and positioning data acquired by the positioning equipment; labeling disease types of radar map data, and generating a training sample set; the disease recognition model is obtained through training by adopting the training sample set and the preset neural network algorithm, so that the urban road underground shallow disease can be recognized through the disease recognition model, the recognition efficiency is improved, the radar map data is combined for recognition, and the recognition accuracy can be ensured.

The method solves the problems that in the traditional method, because the data volume acquired by the ground penetrating radar operation is large, the equipment data transmission is disconnected at any time when transmitted through the common network, and the data uploading interval time is long.
