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 1):
A decoding method for a QR code with one damaged position detection pattern, characterized by comprising the following steps:\n 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; judging whether the two position detection patterns are in an adjacent positional relation or a diagonal positional relation according to the geometrical relation between the boundaries and the vertexes of the two position detection patterns; searching out a location pattern between the two position detection patterns with the positional relation determined according to the positional relation of the two position detection patterns and the position characteristic and the black and white pattern characteristic of the location pattern; 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 according to the two position detection patterns, the location pattern and the data bit width of the QR code pattern; decoding the QR code pattern partitioned with grids.
