An Integrated Hybrid Framework for Crack Detection on Pressed Panels with Baseline-Driven False-Positive Suppression
Geon Park, Yeseul Kong, Penghua Zhang, Gyuhae Park
TL;DR: A baseline-panel–driven correction map that utilizes prior information extracted from healthy panels is introduced that enhances the stability and accuracy of crack detection, enabling more reliable inspection under the challenging lighting conditions of real automotive press lines.
Crack detection on pressed panels is essential for maintaining quality in automotive manufacturing. However, achieving stable inspection is challenging due to strong reflections on metallic surfaces, geometric curvature, and varying illumination conditions. To address these issue…
