ABSTRACT:
A method and apparatus for automatically aligning a field of view of a two-dimensional bar code symbol reading device with a randomly oriented two-dimensional bar code symbol, wherein the symbol comprises a unique locatable pattern of bars and spaces, located along at least one side of the two-dimensioanl bar code. The invention uses standard omnidirectional scanning pattern for reading one-dimensional bar codes to locate the unique pattern in bar code, and works on the bar code located anywhere in the scanner field of view. The invention determines the angle of rotation of the bar code and the spatial location of the bar code in the scanner's field of view.
