Abstract
Apparatus and methods of evaluating packages are provided. In a vision evaluation system embodiment, the system includes a light source, a first and second camera and a control system. The light source provides polarized backlight. The first camera has a first lens positioned to image the polarized back light. A ninety degree polarized filter is positioned between the first lens of the first camera and the light source. The ninety degree polarized filter is polarized 90 degrees from the polarized back light of the light source. The second camera has a second lens that is positioned near the first lens of the first camera. The control system is coupled to control the first and second cameras to take simultaneous images at a given frequency. The control system is further configured to determine locations to analyze based on image data from the first camera. Moreover, the control system is still further configured to analyze the determined locations in associated image data from the second camera. Packages whose image fails the analysis are removed from a packing line.
