Abstract

The present invention provides a method and system for real-time interpretation of three-dimensional ground-penetrating radar for underground space data, including: step S1, performing real-time data processing on real-time data collected by three-dimensional ground-penetrating radar, generating vertical slice image clusters, and performing a first-level model target detection; step S2, generate horizontal slice image clusters according to the detected target body, and perform real-time classification of the secondary model; step S3, search for the longitude and latitude according to the track number recorded in the acquisition process of the confirmed target, and generate a map position; step S4, according to the track number recorded in the acquisition process of the confirmed target, search for the frame number of the video stream according to the track number, and use the key frame rapid extraction method to generate a scene positioning photo; step S5, pop up a multi-window combination in real time, and display the real-time detected target Composite images, map locations and on-site location photos. The invention can well meet the real-time requirements of emergency projects and large-area blind test projects, and can effectively avoid the problem of misidentification.

Description

technical field [0001] The present invention relates to a ground-penetrating radar interpretation method, in particular to a real-time three-dimensional ground-penetrating radar interpretation method for underground space data, and to a system using the three-dimensional ground-penetrating radar real-time interpretation method for underground space data . Background technique [0002] Ground Penetrating Radar, also known as ground penetrating radar, is a non-destructive geophysical detection technology that uses high-frequency electromagnetic waves to determine the structure of shallow strata. By emitting high-frequency pulsed electromagnetic waves (frequency between 1MHz-1GHz) to detect underground media and determine the distribution of underground media, it has the characteristics of simple operation, high detection accuracy, no damage, and fast acquisition speed. It is the most active engineering detection and survey at present. The detection technology has been widely ...

AI Technical Summary

Problems solved by technology

[0003] First, non-real-time data processing and artificial intelligence interpretation cannot achieve high-efficiency on-site parallelism of data collection, data processing, and artificial intelligence interpretation, so that it cannot meet the requirements of emergency projects and large-area blind test projects

Second, the artificial intelligence interpretation based only on the vertical slice image of ground penetrating radar is likely to cause more misidentifications, thereby reducing the accuracy of the interpretation results.

Third, the artificial intelligence interpretation / classification method based on the simple superposition of vertical slices and horizontal slices of ground penetrating radar is also likely to cause more misidentifications, thereby reducing the accuracy of interpretation results. For emptying, etc.
