Interior and exterior crack mapping in a shared 3D model
Structure and inspection scope
The Canton of Zürich required damage mapping on both interior and exterior surfaces of the abutment. Different access conditions called for complementary image acquisition methods.
Inspection methodology
Drone and handheld camera images were combined to reconstruct the structure in 3D. AI-assisted analysis detected, quantified and localised various structural damage types.
Inspection results
Engineers can examine crack patterns on both sides of the abutment within the same spatial reference and distinguish load-induced structural cracking from non-structural surface cracking.
