Abstract

The invention provides a three-dimensional ground penetrating radar real-time interpretation method and system for underground space data, wherein the method comprises the steps: s1, carrying out the real-time data processing of real-time data collected by a three-dimensional ground penetrating radar, generating a vertical slice image cluster, and carrying out the target detection of a first-stage model; s2, generating a horizontal slice image cluster according to the detected target body, and carrying out the real-time classification of a secondary model; s3, searching longitude and latitude according to the track number recorded in the collection process of the confirmed target, and generating a map position; s4, searching a video stream frame number according to the channel number recorded by the confirmed target in the acquisition process, and generating an on-site positioning picture by using a key frame rapid extraction method; s5, popping up a multi-window combination in real time, and displaying the instantly detected composite image of the target, the map position and the field positioning photo. According to the method, the requirements of emergency projects and large-area blind test projects on real-time performance can be well met, and the problem of misrecognition can be effectively avoided.

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.
