History of QR code technology
Foreign research on two-dimensional code technology began at the
end of the 80s of the 20th century, and a variety of code systems
have been developed in the research of two-dimensional code symbol
representation technology, such as PDF417, QR Code, Code 49, Code
16K, Code One, etc. The information density of these QR codes has
been greatly improved compared with the traditional one-dimensional
code, such as PDF417, which is more than 20 times the information
density of the one-dimensional code CodeC39. In terms of QR code
standardization research, the International Association of
Automatic Identification Manufacturers (AIM) and the United States
Standardization Institute (ANSI) have completed the symbol
standards of PDF417, QR Code, Code 49, Code 16K, Code One and other
symbols. The International Standards Technical Committee and the
International Electrotechnical Commission have also established a
technical committee for automatic identification of bar codes, and
have formulated an international standard for QR Code (ISO/IEC
18004:2000 "Technical Specification for Automatic Identification
and Data Acquisition Technology One Code Symbol - QR Code"), and
drafted draft ISO/EC standards for QR codes such as PDF417, Code
16K, Data Matrix, Maxi Code, etc. In terms of the development,
research and production of two-dimensional code equipment, the
reading equipment and symbol generation equipment produced by
equipment manufacturers in United States, Japan and other countries
have been widely used in various two-dimensional code application
systems. As a new information storage, transmission and
identification technology, QR codes have received the attention of
many countries in the world since their birth. United States,
Germany, Japan and other countries have not only applied QR code
technology to the management of various documents by public
security, foreign affairs, military and other departments, but also
applied QR codes to the management of various reports and bills by
customs, taxation and other departments, the management of goods
and goods transportation by commerce, transportation and other
departments, the management of postal parcels by postal
departments, and the automation management of industrial production
lines in the field of industrial production.
The research on QR code technology in China began in 1993. The
China Article Coding Center has translated and tracked the
technical specifications of several commonly used QR codes PDF417,
QRC Code, Data Matrix, Maxi Code, Code 49, Code 16K, and Code One.
With the continuous improvement of China's market economy and the
rapid development of information technology, the domestic demand
for the new technology of QR code is increasing day by day. With
the strong support of the former State Bureau of Quality and
Technical Supervision and relevant state departments, the China
Article Coding Center has continuously deepened its research on QR
code technology. On the basis of digesting relevant foreign
technical data, two national standards for two-dimensional codes
have been formulated: two-dimensional code grid matrix code (SJ/T
11349-2006) and two-dimensional code compact matrix code (SJ/T
11350-2006), which has greatly promoted the research and
development of two-dimensional code with independent intellectual
property rights technology in China.
Currently the most commonly used international DATAMATRIX
two-dimensional code due to the use of dot-matrix method of
composing data, can contain 2300 data information in a data matrix,
although ten years ago when published on the global sensation, but
ten years it is slow progress in the application and promotion of
its application, the reason for this is precisely because of the
DATAMATRIX two-dimensional code of the application of the two
technical barriers need to be crossed: First, how to efficiently
and accurately print it out; Second, how to efficiently and
accurately read it. In order to solve these two key problems, as an
intelligent image recognition technology, machine vision thus shows
its unique importance.
