Embodiment Construction

[0051] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0052] The monogenic wavelet (Monogenic) signal is the result of the two-dimensional extension of the one-dimensional analytical signal. This method combines the wavelet basis of real coefficients with its complex-valued Riesz transform to form a multi-scale monogenic signal analysis, so that each wavelet coefficient All have amplitude, phase and direction information. Therefore, the use of single-cast wavelets to extract the amplitude characteristics of target echoes can improve the clutter suppression effect while retaining the target information more completely, thereby improving the accuracy of target positioning.

[0053] The present invention is a method based on multi-scale monogenic (Monogenic) signal analysis to detect and determine the position of ground-penetrating radar underground targets, such as figure 1 As shown, the details are as follows:

Abstract

The invention relates to a ground penetrating radar underground target position detection method. The method comprises the following steps: a ground penetrating radar B-Scan data are subjected to multi-scale amplitude, phase and direction characteristic component extraction; three characteristic components for the first scale are extracted, and a color image is combined by using an HSB channel representation method; a target area of interest is found out; graying is carried out on the color image in the target area of interest, and edge extraction is carried out on an amplitude image in the target area of interest; a target hyperbolas is positioned; and according to the target hyperbolas, target position determination is realized. the method of the invention does not need data training, and online detection is easily carried out; the target information can be kept in a complete mode, the target positioning precision is enhanced, and as for shallow layer detection, false alarms are not likely to be generated, and non metallic pipeline targets are not likely to be omitted; clutter suppression effects can be enhanced, and strong clutters and target echoes can be effectively distinguished; and the algorithm is simple, and target positioning can be ensured to be quickly carried out.

Description

technical field [0001] The invention relates to a ground-penetrating radar underground target position detection method, which belongs to the field of ground-penetrating radar detection. Background technique [0002] Ground-penetrating radar is an effective shallow underground target detection technology developed rapidly in recent decades. It is a non-destructive detection method with fast detection speed, high resolution, convenient and flexible operation, and low detection cost. With many advantages, it has been widely used in the detection and positioning of underground targets, such as cavities, pipelines, mines, etc. [0003] The two-dimensional echo data detected by ground penetrating radar is called B-Scan data, which is the data basis for subsequent radar signal processing, target recognition and interpretation, and the ground penetrating radar target positioning technology is also based on B-Scan data. The biggest influence on the accurate positioning of the targe...
