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 7):
The decoding method for the QR code with one damaged position detection pattern according to  claim 1 , characterized in that if the two position detection patterns are in the diagonal positional relation, location patterns between the two position detection patterns with the positional relation determined are searched out according to the position characteristic and the black and white pattern characteristic of the location patterns, specifically,\n the two position detection patterns are in the diagonal positional relation; according to the boundaries of the two position detection patterns and the data bit width of the QR code pattern, four possible location pattern regions which overlap with the inner edges of the two position detection patterns and occupy one data bit width are marked out in the region between the two position detection patterns; the number of continuous black pixel points and the number of continuous white pixel points in each of the four possible location pattern regions  19  are recorded separately, and four possible location pattern scales are obtained; a number value similarity threshold is preset, and the two possible location pattern scales meeting the condition that the difference of any two number values is smaller than the number value similarity threshold and perpendicular to each other are screened out from the four possible location pattern scales to serve as the scales of two location pattern regions; patterns corresponding to the two location pattern regions are the location patterns.
