Vial defect inspection cell
Telecentric vision plus an edge segmentation model that inspects 300 sterile vials a minute and rejects through the existing PLC.

- escapes in 2 quarters
The challenge
Human inspectors lost accuracy in the last hour of every shift and one recall would cost more than a year of headcount.
What we built
A controlled-backlight optical rig, a compact segmentation network on an edge accelerator and a reject actuator wired to the line PLC with a full audit record per vial.
Highlights
- Glass defects separated from reflections by lighting, not a bigger model
- Per-part image and verdict stored for audit
- Retrofits onto the existing conveyor
