Image Sensors Used to Inspect for the Presence and Position of Seals

Case Number 420

last update: May 17, 2011

Detection of edges of seals on packaging boxes enables reliable inspections.


The shine and halation caused by the shape and unevenness of objects is removed by a polarization filter. The edges of seals are reliably detected with real-color processing even when there is little contrast between the seal and the box.

Benefit / Efficiency

No time is required to identify the characteristics to ensure contrast between seals and boxes, and inspection results are stable.
