Abstract
A method and system for filtering detection patterns in a QR code is provided in this invention. When multiple detection patterns get into a QR code image due to interference or other reasons, first of all, an side length is determined for each pattern to be detected, and then an average value of the side lengths of multiple patterns to be detected is determined, after which through comparing with a predetermined reference value, patterns to be detected meeting a predetermined condition are determined as detection patterns. An effective solution is provided to fill the gap in the prior art of unable to remove detection patterns caused by interference appropriately when more than three detection patterns are found.
