2024年8月15日 · Introduce a novel method bridging GPR volumetric images to 3D underground pipe map. Avoid pretraining by hyperbola correlation and geometric point cloud segmentation. Extract pipes with noise reduction based on linearity, density and echoes.

2022年3月21日 · Ground-penetrating radar, or GPR, is the tool that many use to ease their pipe-finding frustration. It’s a proven method to reliably locate, measure and map underground objects. Whether it’s copper pipes or PVC — where traditional methods falter and fail, GPR excels.

2024年8月1日 · In this paper, we propose a comprehensive workflow for constructing 3D models of underground pipes. Our approach differs from common classification tasks as it harnesses the 3D information within the GPR data and optimizes traditional 3D GPR processing methods.

Ground Penetrating Radar (GPR) is a powerful tool for identifying water pipe leaks, as it allows for non-destructive testing of the subsurface. GPR works by emitting electromagnetic energy into the ground, which interacts with any materials in its path, including pipes and leaks.

2023年4月1日 · Ground penetrating radar (GPR) is a popular non-destructive method for detecting and locating underground pipelines. However, manual interpretation of a large number of GPR B-scan images is time-consuming, and the results highly relies on the practitioner’s experience and the priori information at hands.

2023年10月12日 · GPR is a promising method for detecting leaks in both metal and PVC pipes; it can detect anomalous changes—caused by water saturation or by recognizing subsurface voids produced by water that has spilled and corroded the material surrounding the pipe—in the characteristics of the material next to the pipes [9,10]. Regardless of the pipe’s ...

To address this challenge, this study proposes an inversion method based on a coupled-learning generative adversarial network (GAN). First, we extract hyperbolic waves from GPR buried-object B-scan images and filter out nonpipe and nonhomogeneous media information from the resulting dielectric constant predictions.

This article proposes a ground-penetrating radar (GPR)-based mapping method, including image processing and target detection technique, which applies to underground pipeline networks.

Pipes. GPR can detect pipes of all sizes, used for utilities and other purposes. Metal pipes are the easiest for GPR to detect due to their strong interaction with the radio signal. However, GPR can locate all variety of PVC and plastic pipes as well. It can locate pipe regardless of whether it is full of water or another material. Void Spaces

2023年4月21日 · GPR detection is a non-invasive imaging technique that uses electromagnetic waves to penetrate the ground and create images of the subsurface. This makes it an ideal tool for mapping pipe networks, as it allows you to see the …
