Automated Detection and Characterization of Cracks on Concrete Using Laser Scanning

Yunfeng Ge et al.

Summary: An innovative approach was developed to automatically measure cracks on concrete using 3D point clouds collected by a terrestrial laser scanner. The approach integrates various techniques to characterize the cracks and accurately determine their dimensions. The developed method was validated using two cases of surface cracks, and it showed good agreement with manual measurements and projection method.

Rock joint detection from 3D point clouds based on colour space

Yunfeng Ge et al.

Summary: A new method based on colour space was proposed for the semi-automatic identification and orientation calculation of rock joints to improve the automation accuracy of rock joint mapping. The method includes four steps: calculating point colour space and point curvature, identifying rock joint sets from point clouds, extracting single rock joints using DBSCAN, and determining the orientation based on the point normals. The effectiveness of the proposed method was verified through examples.
