20110073657 | METHOD AND APPARATUS FOR DETECTING A BARCODE - A method and apparatus for detecting a barcode like region contained in a target object. The method includes capturing an image of the target object, calculating a total confidence value for the captured image, and determining a presence of a barcode in the captured image based on the total confidence value, wherein the total confidence value is calculated as a function of at least one of a first, second, and third confidence values. The method of calculating the confidence values includes calculating the first confidence value based on a vertical projection signal of the barcode like region in the captured image, the second confidence value based on a horizontal projection signal of the barcode like region in the captured image, and the third confidence value based on a start and stop pattern of the barcode like region in the captured image. | 03-31-2011 |

20120138686 | ENHANCED LASER BARCODE SCANNING - A laser scanning device is described. The device includes a laser for projecting a light beam. A mirror is optically coupled to the laser. The mirror reflects the light beam onto a target. A detector generates an analog signal in response to detecting a reflection of the light beam from the target. A processor is capable of modifying a scanning parameter of the laser scanning device. The processor processes the analog signal to generate a digital bar pattern and can embed the scanning parameter in the digital bar pattern. | 06-07-2012 |
20130001311 | METHOD OF AND READER FOR ELECTRO-OPTICALLY READING SYMBOLS ON CURVED SURFACES - Symbols having symbologies with multi-unit, bar and space element, start and stop patterns on curved surfaces of objects, are electro-optically read by capturing light from a target symbol over a scan line, and by generating an electrical analog signal indicative of the captured light over the scan line. A controller digitizes the electrical analog signal into a digitized signal, decodes the digitized signal between the start and stop patterns into valid characters of the target symbol, identifies leading and trailing waveform portions of the analog signal indicative of the start and stop patterns, matches the identified leading and trailing waveform portions of the analog signal against known analog waveforms of the start and stop patterns of the target symbol, and verifies that a match has occurred when the matching between the leading and trailing waveform portions and the known analog waveforms exceeds a known threshold correlation. | 01-03-2013 |
