Point-wise deformation analysis of 3D models for structural health monitoring

  • A new point-wise deformation analysis was developed to automatically measure deflection in 3D models of structural systems

  • A direct 3D geometric comparison was implemented to accurately detect and quantify changes 

  • Utilizing a statistical approach to improve the robustness of the algorithms in presence of outliers/noise

  • Using advanced distance metrics to take into account variability in local point density, roughness, and registration uncertainty

  • The findings indicate measurement accuracy of 0.2 mm, making the algorithm suitable for structural condition assessment
