Pin Dimensional Measurement with AI Segmentation

Software: MVTec Merlic
Key Tools: 2D Dimensional , AI Segmentation, AI Classification.
Description : Designed and implemented a fully automated inspection solution for microdot connectors, focusing on ultra-small components with tight dimensional tolerances (e.g., Ø0.03 in with ±0.005 in tolerance). The system performed multiple precise 2D measurements, including:
Overall length and barrel length
Tip and pin diameters
Assembly angle
Bulge diameter (axial)
Bulge position offset (for placement verification)
To ensure robust measurement of the axial bulge diameter, a custom AI segmentation model was trained to consistently select the relevant region, enabling accurate dimensional analysis and position validation.
