228 Vision Verification Module
As shown in the illustration above, when a card enters the Vision Verification
module the camera takes a picture of the front and back of the card and sends the
images to the system Controller for analysis. While the Controller is analyzing the
image, the flipper mechanism returns the card to its original position in
preparation for leaving the module. If the card stock is correct, the card is
personalized in subsequent modules. If the card stock is not correct, the card
passes through subsequent modules without being altered and ends in the reject
tray. The process is similar if the Vision Verification module is positioned after
the personalization modules.
The next illustration depicts what happens in the Controller during the analysis
phase of card
stock verification. The Controller software analyzes the image of
the current card based on the information in the Card Setup or Card Stock Setup
and generates a Score of 0 to 100. (Higher scores indicate better matches.) Then
the Score is compared to the Threshold Value established in the Card Setup or
Card Stock Setup. If the Score is less than the Threshold Value, the card is
rejected.
