Abstract
Systems, methods, and computer-readable media are disclosed for long range barcode scanning. In one embodiment, an example method may include determining a signal representative of a portion of light reflected from a barcode, determining respective values at one or more valleys and peaks of the signal, determining that a first peak represents a first narrow barcode element of the barcode, and determining that the third peak represents a second narrow barcode element of the barcode. Example methods may include determining a first edge position of the first narrow barcode element along a first portion of the signal, determining a second edge position of the second narrow barcode element along a second portion of the signal, and determining a path between the first edge position to the second edge position.
