Summary:The embodiment of the present invention provides a fast response code search method and device. The method comprises the steps of: obtaining a target image; determining data of matching points according to widths of N alternately deep and light color sections of the target image in a transverse direction and a vertical direction, wherein N is a positive integer; performing fast response code searching according to the data of the matching points; in the process of determination of the data of the matching points of the target image, if the width of the color section in a current set does not meet a preset proportion requirement, and when a first color section which cannot meet the proportion requirement is the ith color section, determining the data of the width of the first color sectionwhich cannot meet the proportion requirement as data of the width of (i+2)th color section to obtain the data of the width of the next set of color section, wherein i=0, 1 or 2; and when the first color section which cannot m
