Abstract
A scanning system for orienting bar codes use a first stage made up of a low-resolution scanner and a digital signal processor (DSP), and a second stage made up of a high-resolution scanner and a decoder. The first stage scans the surface of an object to obtain an image, which the DSP analyzes to determine the location and orientation of any bar codes. The DSP does this by dividing the image into windows and finding the windows which contain part of a bar code. The second stage receives the results from the DSP and scans the bar code on the object.
