ABSTRACT:
A system and method for determining the thickness of a mail piece is provided. A first image of at least a portion of a surface of a mail piece is captured using a first optical axis for a feature on the surface of the mail piece. A second image of the feature is captured after the mail piece has moved a distance using a second optical axis that is angled with respect to the first optical axis. The first and second images are correlated to determine a displacement of the feature, and the thickness of the mail piece is determined based on the displacement and the angle between the first and second optical axes.
