GPR B-Scan dataset

The original data in this dataset are derived from the ground-penetrating radar (GPR) measurements published in: Liu, H., et al. Automatic recognition and localization of underground pipelines in GPR B-scans using a deep learning model. Tunnelling and Underground Space Technology, 2023, 134: 104861. As the original dataset does not include annotations suitable for object detection tasks, we manually annotated the data following a consistent labeling protocol. The resulting annotated dataset is provided in this repository to support reproducibility and enable further research in non-metal pipeline detection using GPR images.
