A2D Bar Code Detection System Based on CCD

In order to solve the problem of bar code defaced products reaching market,a system development program is proposed in this paper,which is composed of high-speed CCD,JAVAsoftware decoding,and information contrast and processingwith Excel VBA.The architecture of hardware and software development based on QR 2D bar code decoding are discussed.Test result demonstrates that the system possesses the characteristic of cheap investment and high practicability.
