The present invention provides a multi-QR code identification method. An original image is filtered, the contrast of the original image is amplified, the two-dimensional features are enhanced, and multiple position detection graphs are searched from the image; the position detection graphs, belonging to the same QR code, in the multiple position detection graphs are set to be the same group; and the limited calculation resource is flexibly distributed in each part, and in the condition of ensuring the accuracy, and the consumed time of the process is controlled in the acceptable range.
