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 8):
The decoding method for the QR code with one damaged position detection pattern according to  claim 7 , characterized in that if the two position detection patterns are in the diagonal positional relation, the received QR code image is partitioned with grids according to the two position detection patterns, the two location patterns and the data bit width of the QR code pattern, specifically,\n the two position detection patterns are in the diagonal positional relation; the region where the QR code pattern is located is determined according to the positions of the two position detection patterns and the positions of the two location patterns; each location pattern region is partitioned in the direction perpendicular to the length direction of the location pattern region according to the boundaries between the black pixel points and the white pixel points in the location pattern; the two position detection patterns are partitioned in the two direction parallel to the four boundaries according to the data bit width.
