Design and Analysis of the Three-Dimensional Bar Code

The bar code need increase its information capacity because of its widespread use. In this paper, a novel bar code- three-dimensional bar code is proposed. It can greatly increase the information capacity. The three-dimensional bar code combines the variety of widths, the variety of colors and a vertical array to provide significantly more information content. At first, the encoding technology of bar code is discussed. Then the three-dimensional bar code is proposed on the basis of the two-dimensional bar code. The design principle and information content of the three-dimensional bar is also discussed. Finally, the experiment proves the three-dimensional bar code can withstand the influence of noise and blur.
