Provided are a method for generating a micro-graph group for information mapping and a method for recognizing a micro-graph group. A micro-graph group and a mapping table are used to realize conversion and connection between various pieces of information so as to realize human-machine interaction. The method for generating a micro-graph group for information mapping comprises the following steps: selecting a digital conversion system; selecting the shape of a micro-graph, wherein the micro-graph comprises: a rule region formed by combining a plurality of two-dimensional digital pictures and a positioning region consisting of basic auxiliary image mapping sign units, and each of the plurality of two-dimensional digital pictures consists of the basic image mapping sign units determined according to the selected digital conversion system; and determining the size of the micro-graph group by adjusting the border width of the micro-graph and/or the distance between the two-dimensional digital pictures. The micro-graph can be drawn by a computer, the micro-graph can be formed on a physical medium by means of printing, the micro-graph can be recognized and analyzed by means of a mask and the mapping table after being pre-processed, and information data of each attribute can be output at a terminal.
