    摘要: Described is a system and method for bar code detection. The method comprises generating a digitized bar pattern (DBP) including a series of elements corresponding to elements of a scanned bar code, and identifying a first set of margins around a first portion of the series of elements. When an attempt to decode the first portion is unsuccessful, the first portion is analyzed to determine a second set of margins around a second portion of the series of elements, the second set of margins being within the first set of margins, and the second portion is input to a decoding algorithm.

    摘要: Methods, systems, and apparatuses for identifying items carried by a mobile structure are described. At a first location of the mobile structure, a first radio frequency identification (RFID) read signal is directed to a load carried by the mobile structure to identify an initial set of RFID tags. At a subsequent location of the mobile structure, a subsequent read signal is directed to the load carried by the mobile structure to identify a subsequent set of RFID tags. The initial set of RFID tags and the subsequent set of RFID tags are compared to determine a set of RFID tags associated with the load.

    摘要: 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.

    摘要: Methods and apparatus for adjusting image capture settings, such as, for example, exposure time and external illumination through determining ambient luminance conditions prior to a request to analyze a captured image. Since image capture settings are determined before an analyze request, a device can use images captured before or very close to the request to decode a target dataform.
