Regional illumination-recipe fusion on curved viewing glass
The viewing area, transition region and flange of curved viewing glass behave differently optically. A mould-mark or crack candidate that lacks contrast under one light needs evaluation with different viewpoints and illumination evidence.
Proposed output: regional defect mask, illumination evidence used and review decision. Camera count, defect targets and line cycle require real-sample validation; this scene is illustrative.

Solution approach
Sequentially acquire transmitted, patterned-reflection and diffuse/darkfield illumination recipes in one tunnel. Register defect regions in the same part coordinates and apply separate viewing, transition and flange ROI rules. Fuse AI segmentation with rule-based evidence; never automatically accept unseen regions.
