A recently granted patent (Publication Number: US11928550B2) outlines a method and apparatus for decoding barcodes in an image of an environment captured by an imaging device. The method involves obtaining image data from an image sensor, decoding a subset of barcodes, determining parameters representing the arrangement of barcodes in the image, identifying possible locations for additional barcodes, attempting to decode these barcodes, and transmitting the decoded data to a host. The apparatus includes a barcode decoder and a communication interface to carry out these functions efficiently.

The patent details various aspects of the method, including the use of different barcode decoding algorithms for speed and read rate, determining parameters based on location information, and confirming the absence of barcodes in certain locations. The arrangement of barcodes is based on a rectangular grid, with logical lines projected from barcode centers to determine intersections and possible locations. The method also involves processing image data to confirm the absence of barcodes in specific locations. The patent aims to enhance barcode decoding efficiency and accuracy in various environments by predicting barcode arrangements and decoding subsets of barcodes systematically.
