QR code structure link optimization method

Abstract

The invention provides a QR code structure link optimization method. The method comprises the following steps of indicating all QR code symbols in the structure link by using a header; wherein the header at least comprises an optimized structure link mode indicator and an optimized link identifier; wherein the optimized structure link mode indicator is used for indicating that the QR code symbol adopts an optimized structure link mode, and the optimized link identifier adopts an equipment number of equipment for generating the QR code symbol and a sequence number of the structure link generated by the equipment to identify the optimized structure link. The method can provide the optimized QR code symbol structure link which can perform structure link on more QR code symbols, structure linkidentifiers cannot be collided, and QR code symbol interference from other groups of structure links can be automatically eliminated.

[0002] The quick response matrix code (QR code) in the two-dimensional code is a commonly used information storage, transmission and identification technology, which has been widely used. It has the following characteristics: 1) large information capacity; 2) wide coding range; 3) 4) Reliable decoding; 5) Encryption measures can be introduced; 6) Low cost, easy to manufacture, and durable; 7) The shape and size of the two-dimensional code symbol can be changed; 8) Easy to read equipment Obtained; 9) The speed of information transmission is fast, and there is no need for handshaking between transmission devices (such as WIFI, Bluetooth, which require a handshake process, which is not suitable for rapid information transmission), etc.

In the current QR code standard (GB / T18284-2000, ISO / IEC18004:2006, JISX0510:2004), for example, the international standard ISO / IEC18004:2006 provides a structural additional mode, which provides a maximum of 16 QR codes symbols; the Chinese standard GB / T18284-2000 provides a structural linking mode, which provides linking up to 16 QR code symbols; however, there are still two structural linking (or structural addition) modes in these standards Disadvantages: First, only one byte (1Byte) is used to represent the identification of the same group of structure link QR code symbols. Since the number of identification digits is too short (only one byte, only 8 bits), the identification of different group structure links is easy to occur Repeatedly, the structural link identification collision occurs, resulting in the structural link identification not being unique and unable to uniquely identify a group of structural links; second, the link length can only support links with a maximum of 16 QR code symbols, and if it exceeds 16 QR code symbols, it cannot , resulting in limited expansion of information capacity
