Abstract:
The invention provides a decoding method and system for a QR code with one damaged position detection pattern. The decoding method comprises the steps: binarizing a received image containing a QR code pattern and searching for position detection patterns, decoding the QR code pattern through the following method if two position detection patterns are searched out, recording the linear equations of the boundaries of the two position detection patterns and the vertex coordinates of the two position detection patterns and calculating the data bit width of the QR code pattern, searching out a location pattern between the two position detection patterns with the positional relation determined, determining the region where the QR code pattern is located according to the two position detection patters and the location pattern, partitioning the region where the QR code pattern is located with grids, and decoding the QR code pattern partitioned with grids.

Claim (Index 4):
The decoding method for the QR code with one damaged position detection pattern according to  claim 1 , characterized in that whether the two position detection patterns are in the adjacent positional relation or the diagonal positional relation is judged according to the geometrical relation between the boundaries and the vertexes of the two position detection patterns, specifically,\n the linear equations of the first pair of boundaries, perpendicular to each other, of one position detection patter are obtained; the linear equations of the four boundaries of the other position detection pattern are obtained; a linear distance threshold is preset, and the distances from every two parallel boundaries of the four boundaries of the other position detection pattern to the boundary, in parallel with the two parallel boundaries, in the first pair of boundaries are calculated separately, so that four distance values are obtained; if one of the four distance values is smaller than or equal to the linear distance threshold, it is judged that the two position detection patterns are in the adjacent positional relation, otherwise, it is judged that the two position detection patterns are in the diagonal positional relation.
