Automated 3D spatial damage detection

Automated 3D Spatial Damage Detection in Structural Systems for Finite Element Model Updating

An automated computer-vision based method was developed to locate and quantify section loss damage
In order to preserve data integrity and resolve localized high-fidelity details, direct 3D point cloud analysis was implemented
Utilizing the accurate geometric information of the identified damages to locally update the existing 3D solid model of the structure which later facilitates the finite element analysis
Experimental results demonstrate that the developed method is able to accurately and efficiently detect damages with dimensions about 10 mm or larger
