New methods combine laser scanning and image correlation for structural defect detection

By PulseAugur Editorial · [1 sources] ·

Researchers have developed two non-contact methods for detecting and quantifying structural defects in steel components. One method uses high-resolution laser scanning to create 3D point clouds, allowing for the localization and measurement of visible damage. The second approach combines 3D digital image correlation with finite element model updating to infer subsurface abnormalities from their influence on surface deformation. Both techniques were evaluated on steel beams with controlled defects and demonstrated the ability to identify and quantify damage, offering complementary information for comprehensive structural condition assessment.

    Integrated Laser Scanning and Image-Based Topology Optimization Techniques for Detection and Quantification of Visible and Subsurface Structural Defects

    arXiv:2609.01808v1 Announce Type: new Abstract: Reliable characterization of structural defects requires methods capable of resolving both directly observable surface damage and damage that is not visible from the inspected surface. This study presents two complementary non-conta…
