Abstract: Abstract In the tire manufacturing field, the pursuit of uncompromised product quality stands as a cornerstone. This paper introduces an innovative multimodal approach aimed at automating the tire quality control process through the use of deep learning on data obtained from stereo-photometric cameras meticulously integrated into a purpose-built, sophisticated tire acquisition system capable of comprehensive data capture across all tire zones. The defects sought exhibit significant variations in size (ranging from a few millimeters to several tens of centimeters) and type (including abnormal stains during processing, marks resulting from demolding issues, foreign particles, air bubbles, deformations, etc.). Our proposed methodology comprises two distinct stages: an initial instance segmentation phase for defect detection and localization, followed by a classification stage based on severity levels, integrating features extracted from the detection network of the first stage alongside tire metadata. Experimental validation demonstrates that the proposed approach achieves automation objectives, attaining satisfactory results in terms of defect detection and classification according to severity, with a F1 score between 0.7 and 0.89 depending on the tire zone. In addition, this study presents a novel method applicable to all tire areas, addressing a wide variety of defects within the domain.
