Those sensors scan surfaces in nanometer scale and generate point clouds. This data can be used to detect surface defects. Such anomalies should be identified during the inspection process to assess the current condition of the workpiece. Deep learning algorithms can be used to evaluate the data. However, in the domain of 3D data, the challenge of obtaining training data is amplified due to the time-consuming labeling process. Therefore, this work introduces an algorithm that combines surface features, like cracks, into surface data to generate new labeled training data. The resulting dataset is then used to train a deep learning algorithm to segment the cracks in the point cloud data. The results indicate that the augmented data enhances the training process.en2212-8271Procedia CIRP2025437442Elsevierhttps://creativecommons.org/licenses/by-nc-nd/4.0/3d datadata augmentationMachine learningsurface inspectionTechnology::629: Other Branches::629.1: Aviation::629.13: Aviation EngineeringTechnology::620: Engineering::620.1: Engineering Mechanics and Materials Science::620.11: Engineering MaterialsComputer Science, Information and General Works::006: Special computer methods::006.3: Artificial IntelligenceA data augmentation algorithm for surface inspection in point cloud dataConference Paperhttps://doi.org/10.15480/882.1540710.1016/j.procir.2025.02.14210.15480/882.15407Conference Paper
