3D Grid on Reinforced Concrete — Welded Mesh Overlap for Rebar Picking
Description
3D grid acquired on a reinforced concrete slab with a GSSI NX25 stepped-frequency antenna, over a 1.2 × 0.6 m area. The slab contains two layers of welded wire mesh with an overlap zone, where the reinforcement density locally doubles.
That overlap is what makes the dataset useful for training: manual picking remains straightforward on the regular part of the mesh, while the lap zone produces closely spaced, partly merged hyperbolas — exactly the configuration where automatic detection tends to miss bars or merge them. Comparing manual and automatic picking in GPRviewer on the same grid shows where each approach reaches its limits.
Raw unprocessed files, suitable for rebar picking practice, cover measurement, and benchmarking automatic detection algorithms.
