Ballot and its identification method based on two-dimensional code

Abstract

The invention provides a vote based on two-dimensional codes and an identification method thereof. The two-dimensional codes are arranged on the vote, and mode data and flag data are written in the two-dimensional codes. The identification method of the vote comprises the following steps: identifying the two-dimensional codes in a fixed position, recording a central coordinate, and reading out data content of the two-dimensional codes; analyzing the data content to be in a defined flag data format for analysis, and determining positive and negative sequence of a vote image; assembling and recovering the data into the mode data according to a number sequence appointed in the data format; converting relative coordinates of content blocks recorded in the mode data into an absolute coordinate system; searching out all synchronous track pairs according to search regions recorded in synchronous tracks; finding content block identification regions according to the horizontal coordinates of the content blocks and the longitudinal coordinates of the synchronous tracks obtained by conversion; identifying by content block identification parameters in the mode data; generating corresponding result data according to mode content block information and identification results. According to the vote and the identification method thereof, a distribution mode is not required, various vote types are supported, and the fault-tolerant capability is good.

Description

【Technical field】 [0001] The invention relates to the technical field of ballot identification, in particular to a two-dimensional code-based ballot pattern and an identification method thereof. 【Background technique】 [0002] At present, in the election work, the ballot papers used are as follows: figure 1 As shown, it includes a ballot type mark block 10', a reverse mark block 20', a positioning mark block 30', a content to be positioned 40', a left synchronous track 50' and a right synchronous track 60'. The way to identify this ballot is: [0003] (1) Obtain pattern information for ballot identification, mainly including ballot type marking block 10', forward and backward marking block 20', synchronization track (left and right horizontal black blocks, respectively left synchronization track 50' and right synchronization track 60 ’), the number, definition, relative coordinates, size, and identification parameters of each type of identification area; [0004] (2) Load...

AI Technical Summary

Problems solved by technology

[0014] (1) Pattern distribution is cumbersome

Whenever the pattern changes, the changed pattern data must be redistributed to the ballot recognition module. If there is an omission in this process, the recognition results will be inconsistent;

[0015] (2) The types of votes supported by the same model are limited

For example, the existing ballot type (ballot type marking block 10') only has 6 black and white blocks to distinguish, and supports up to 64 kinds of ballots. If it exceeds, the ballot style must be changed;

[0016] (3) Ballot type marking has no fault tolerance

This black-and-white block coding method has almost no fault tolerance, and a little error will result in an invalid ticket
