Abstract:
The invention relates to the field of data identification, in particular to a technique for forming and capturing a two-dimensional code. The invention provides a method for forming and capturing a two-dimensional code positioning dot matrix for rapid positioning. The method for forming the two-dimensional code positioning point lattice comprises the following steps: Setting or reading the positioning point data lattice; drawing four central symmetric primary positioning point lattice on the setting background; and adding the positioning interval area to the periphery of the primary positioning point lattice. The invention solves the technical problems of long locating time and high locating error rate in 2d code recognition, strengthens the reliability of two-dimensional code locating, improves the identifying efficiency, and reduces the pollution of locating points and data.
