Abstract
In this work, a GPR (ground penetrating radar) development is presented as a non-destructive technique. It allows the visualization of water supply system (WSS) pipelines buried into the ground. The main scope is in image (radargram) processing obtained from GPR, to ob tain improved data visualization. For the application of the technique, laboratory essays have been conducted. These essays were performed by burying a commonly used pipe in a tank that emu lates a small ground parcel. The images obtained were analysed and particular differences between them were observed. From this ensemble of images, a 3D model was generated to obtain better visualization and analysis of the pipeline. As a result, a clearer vision of the pipeline, as well as of other surrounding characteristics, was observed. This work is intended to obtain 3D models for an upgraded visualization of radargrams mainly focused on users that have poor knowledge of GPR and radargrams analysis. In the future, the development of a more powerful tool that allows the inspection of WSSs is pursued, allowing not only the location of pipelines, but also obtaining their depth, diameter and possible anomalies, among other interesting characteristics.
