Acquisition & Alignment

Capture: HIKROBOT MV-CU060-10UC · 3072 × 2048 · 10–50 mm zoom lens · polarized illumination. Collection: 100 PCB surfaces, seven images per surface across dark, normal, and bright illumination; 668 pairs retained after filtering. Alignment: Each pair was annotated with a homography and verified through manual inspection and reprojection error.
