Abstract
Disclosed is a linear barcode scanning system and associated methods for reading a linear barcode borne by an item during transport of the item along a direction of transport by a transport system. A displacement between consecutive scanline samples is determined based on movement imparted to the item from an item-transport system. Image data representing an area of the linear barcode located between positions of the linear barcode corresponding to the consecutive scanline samples is synthesized by quantizing a portion of a first one of the consecutive scanline samples and extending the quantized portion along a direction of the displacement to provide for a depiction of the area of the linear barcode.
