WELDING INSPECTION USING NOVEL SPECULARITY FEATURES AND A ONE-CLASS SVM

Fabian Timm, Sascha Klement, Erhardt Barth, Thomas Martinetz

Abstract

We present a framework for automatic inspection of welding seams based on specular reflections. Therefore, we introduce a novel feature set -- called specularity features (SPECs) -- describing statistical properties of specular reflections. For classification we use a one-class support-vector approach. The SPECs significantly outperform statistical geometric features and raw pixel intensities, since they capture more complex characteristics and depencies of shape and geometry.We obtain an error rate of 9%, which corresponds to the level of human performance.
