Abstract
In this work, the research question of how to inspect the quality of bends in 3D point cloud representations of sheet metal parts is investigated. The manufacturing system responsible for fabricating the sheet metal parts is introduced, alongside the currently available scanned data. A novel pipeline is developed, which automatically pre-processes the scanned point clouds, triangulates the positions of the bends and measures their total inclination angle, as well as their arc length. The method is tested on ideal data, which proved that it is conceptually sound. Subsequent experiments are conducted to test the method's robustness to noise, as well as its ability to provide realistic results on the real scans.
