Abstract

The invention provides a two-dimensional code generation method, a two-dimensional code reading method and related devices. In the two-dimensional code generation process, the two-dimensional code bearing data volume of a single two-dimensional code can be determined according to the screen size data of the electronic terminal and the preset color block arrangement density, the to-be-transmitted data with the large data volume is divided into N data fragments with the small data volume, and a two-dimensional code image is generated for each data fragment. The electronic terminal can circularly display the N two-dimensional code images according to a preset display refresh rate. Because the arrangement density of the color blocks of the single two-dimensional code image is predetermined according to the precision of the two-dimensional code acquisition equipment, even if the precision of the two-dimensional code acquisition equipment is low, each complete two-dimensional code image can be acquired, and the accuracy of the two-dimensional code image is improved. Therefore, the two-dimensional code reading device can obtain the to-be-transmitted data with a large data size according to the two-dimensional code images acquired by the two-dimensional code acquisition device. Therefore, low-cost and large-data-volume information transmission can be realized at the same time.
