Inspection des surfaces et porosit\u00e9 des mat\u00e9riaux m\u00e9talliques avec vision artificielle et apprentissage automatique<\/p>\n\n\n\n
In this talk, I will present two recent works carried out at the University of Le\u00f3n on applying computer vision and machine learning to surface inspection in metal additive manufacturing. The first one focuses on non-contact estimation of arithmetical mean roughness (Ra) in stainless-steel parts. We developed an image-based methodology that combines classical texture descriptors (Haralick, LBP and Dense SIFT) with regression models to predict surface roughness from simple photographs.<\/p>\n\n\n\n
The second work addresses defect detection in aluminium alloy castings produced using 3D-printed molds via binder jetting. We introduce the Porosity Detection Corpus, a dataset of metallographic images annotated with shrinkage and gas pores, and evaluate a YOLO-based object detection system to automatically locate and classify these defects.<\/p>\n\n\n\n
