Abstract

The invention discloses an automatic identification method and system for a pipeline target in ground penetrating radar data. According to the automatic identification method and system for a pipelinetarget in ground penetrating radar data, the positioning of a pipeline feature (hyperbolic curve) region in an image is identified by using a regional convolutional neural network; the positioning isaccurate and rapid, and the training time of a model is short; compared with the traditional Hough transform, the method for extracting the pipeline parameters from the pipeline feature region by using the cross-correlation operation and the Hough transform of the one-dimensional parameter space has the advantages that the operation time is shorter, and the requirement on hardware is low; and compared with a traditional full-graph search and calculation mode, the mode of carrying out region identification on the full-graph lines and then extracting the parameters from the regions has the advantages that the calculation of non-feature regions is avoided, and the calculation efficiency is greatly improved.

Description

technical field

[0001] The invention relates to the field of ground-penetrating radar, in particular to data processing when ground-penetrating radar detects underground pipelines, and more specifically, to an automatic identification method and system for pipeline targets in ground-penetrating radar data. Background technique

[0002] At present, there are three main ways to extract pipeline parameters from ground penetrating radar data: migration processing, Hough transform and pattern recognition.

[0003] The working principle of migration processing is similar to the principle of seismic reflection wave exploration, both of which are migration imaging technology based on wave equation, which is the main technology used in the application of ground penetrating radar in my country at present. The search for pipelines is realized by presetting a wave velocity of electromagnetic waves propagating underground, and offsetting and homing the pipeline signals. The principle of...
