With the development of automatic identification technology and the popularity of smart phones carrying high-definition cameras among the public, application of two-dimensional code has developed rapidly. In this paper, we will expound the research status of two-dimensional code detection methods, including binarization method, Inspection area polarization method and distortion correction method, and summarize the research status of large-capacity two-dimensional code and the development trend of color two-dimensional code technology.
