Embodiment Construction

[0064] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.

[0065] In order to better understand the content of the present invention, it is necessary to understand the basic knowledge of the colors used in the present invention. The generation of the color involved in the present invention is divided into two categories: transmission and reflection. Transmission is usually used for display and CCD imaging. absorbed. In a typical RGB color system, each pixel is usually composed of at least one pixel of red R, green G, and blue B in the pre-transmission filter of the electrically coupled device (CCD), because only the same color as the filter , is perceived by the CCD element, and the perceived signal is divided into several levels according to the int...

Abstract

The invention discloses a matrix type two-dimensional code. An image of the matrix type two-dimensional code is formed by arranging a plurality of color blocks in a rectangular array mode, a circle ofcolor blocks at the edge of the image form a positioning area, and the color blocks in the image form a coding area. The positioning area comprises an L-shaped edge and a positioning edge opposite tothe L-shaped edge. The matrix type two-dimensional code is characterized in that the the colors of the color blocks comprise at least three colors of eight colors including three RGB standard colors,four CMYK standard colors and white color, and the positioning edge is formed by alternately arranging the color blocks which are filtered by any one color channel in RGB and then are black and the color blocks which are filtered by the same color channel and then are white. On the basis of an original Datamtrix data structure, six colors and original black and white two colors are added to forma new color channel to construct the color two-dimensional code, the coding capacity is improved to 3 times of the original coding capacity, and meanwhile the color two-dimensional code is kept compatible with an existing black and white Datamtrix coding system to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional codes, and in particular relates to a matrix two-dimensional code, its generation and decoding methods and its equipment. Background technique [0002] Datamatrix matrix two-dimensional code is widely used because of its advantages of high coding density and small size. However, with more and more application fields of two-dimensional codes, the information capacity required by two-dimensional codes is also increasing. But in some fields, the space that can be used to mark two-dimensional codes is very limited, for example, the storage tubes used to store pharmaceutical compounds, nucleic acids or trace samples are small in volume, but the number is large and cannot be repeated. Limited by the resolution of the code reading equipment and the area of ​​the bottom of the tube, increasing the number of two-dimensional code matrixes to increase the encoding information capacity is close to th...
