Originální abstrakt

Non-destructive testing (NDT) of 3D-printed concrete is challenging due to complex geometries and layer-dependent material heterogeneity. Photogrammetry captures surface geometry, but its outputs cannot be directly linked to NDT values. This study presents a workflow that integrates photogrammetric models with rebound hammer measurements and applies radial basis function (RBF) interpolation to visualize near-surface strength. Each measurement point is matched to its 3D coordinates on the mesh, enabling consistent data integration and automated mapping. The RBF visualization distinguishes between measured, interpolated, and unsupported regions and highlights weak zones at layer interfaces and areas affected by printing irregularities. The approach provides an effective tool for assessing surface uniformity in 3D-printed concrete and supports future diagnostic methods combining geometry and NDT data.
