VISOR® Multishot renders even the smallest height differences visible

VISOR® Advanced mit Multishot-Technologie

 

Raised or recessed object details – such as embossed digits and characters on a credit card – are difficult to detect with standard image processing methods. Even use of lateral lighting generally results in poorly identifiable contours due to overexposure and shadows. We have remedied this situation by equipping our VISOR® series of vision sensors with the new multishot function.

Contours now stand out clearly so that raised or recessed letters and digits can be easily read, e.g. using the vision sensor’s OCR function. Other application examples for VISOR® Multishot are:

  • Reading of data matrix codes moulded directly into plastic surfaces
  • Detection of damage such as dents or scratches
  • Recognition of raised adhesive beads on the same coloured background
  • Elimination of changing backgrounds (e.g. in packaging industry)

The following application examples compare images taken with multishot technology (pictured at the bottom) and without (pictured at the top):
