Abstract:
The invention provides a detection method and system for characteristic patterns of Han Xin codes. The detection method comprises the steps: binarizing a received two-dimensional code image, scanning the two-dimensional code image line-by-line and column-by-column so as to search out the four vertexes of a Han Xin code region, connecting every two vertexes of the four vertexes so as to form the four boundaries and two diagonal lines of the Han Xin code region, searching out four characteristic line segments starting from the vertexes and having the continuous binarization values 1, 0, 1, 0, 1 from the two diagonal lines and also searching out the end points of the characteristic line segments, and calculating the boundaries and the data bit width of position detection patterns of the Han Xin code according to the start points and the end points of the characteristic line segments.

Claim (Index 5):
The detection method for the characteristic patterns of Han Xin codes according to  claim 4 , characterized in that whether the similarities between the characteristic proportions and the standard characteristic proportion of the Han Xin code are within the range of the proportion threshold is not is judged, specifically,\n initial data of the characteristic proportions are converted into data identical with the initial data of the standard characteristic proportion of the Han Xin code, and all other data of the characteristic proportions are equivalently converted, so that converted characteristic proportions are obtained; the differences between the data, except the initial data, of the converted characteristic proportions and the data on the corresponding bits of the standard characteristic proportion of the Han Xin code are calculated, and the absolute values of the differences are worked out; if the absolute value corresponding to each bit is smaller than the proportion threshold, the similarities between the characteristic proportions and the standard characteristic proportion of the Han Xin code are smaller than the proportion threshold.
