1. the generation method of a three-dimensional identifying code is characterized in that, comprises the steps:

  • Prepare two parts of irregular scatter diagrams;

    Determine the content of identifying code, the content of this identifying code is a bianry image;

    First part of scatter diagram cut according to the shape of identifying code content, at first the identifying code content is overlapped with scatter diagram, the pixel for expression content in the identifying code content keeps pixel originally to scatter diagram;

    For the pixel of not representing content in the identifying code content, scatter diagram is deleted this pixel, be changed to " transparent ";

    First part of scatter diagram after the cutting copied as two parts, and portion carries out displacement to the right, and as the left content of three-dimensional identifying code, another part is to left dislocation, as the right content of three-dimensional identifying code;

    Second part of scatter diagram copied as two parts, respectively as the left and right Background of three-dimensional identifying code, to left Background to left dislocation, to the displacement to the right of right Background;

    Left Background level is carried out nonlinear deformation left obtain new left Background;

    Right Background level is carried out nonlinear deformation to the right obtain new right Background;

    Left content is covered on the left Background, obtain the left figure of three-dimensional identifying code;

    Right content is covered on the right Background, obtain the right figure of three-dimensional identifying code;

    The left figure and the right figure of three-dimensional identifying code are synthesized stereographic map.
