Abstract

A system for high speed acquisition and decoding of a barcode symbol locates potential barcode candidates within a scanned image and filters the candidates to eliminate invalid data. The system permits computational resources to be focused on decoding information most likely to be an actual barcode symbol. Once a potential barcode candidate has been located, the barcode symbol is processed to determine the barcode orientation and symbology. Each element of the barcode symbol is then located, even if all elements are not visible in the original image, and the barcode symbol is decoded in accordance with the specific symbology.
