360° Graphical inspection for cylindrical containers

Circumspect is perfect for applications that require graphical inspection of a round or cylindrical container. Cylindrical containers often pose a challenge for inspection systems because it is usually impossible to control where the label is facing on a production line. If the goal is to inspect a graphic or allergen text, how can this be done after the label is applied to the container? Circumspect is the solution for clients in the food & beverage industry who want to have end-of-process inspection of a round product.

The CircumSpect® system creates a 360 degree view of the containers using 4 side-mounted cameras. The software algorithm combines the 4 images into one continuous “un-wrap” image of the entire side circumference. The un-wrap image can then be processed by a wide range of standard machine vision tools. No matter what direction the bottle faces, the un-wrap image will always be the same.

The vision tools available for use include:

  • Pattern matching
  • Pattern inspection
  • Gauging
  • Brightness inspection
  • Color matching
  • Linear barcode reading
  • 2D barcode reading
  • Optical character verification (OCV) of well-printed codes
  • Multiple vision tools may be applied to each image and inspection recipe

A strong recipe manager is standard on the CircumSpect® system. This allows users to quickly switch between pre-configured recipes and transfer recipes from one system to another. VAIA will work with clients on any specific communication requirements, such as how to automatically upload recipes based on the client’s master production schedule or scanning a work-order.
