Method and system for filtering detection patterns in a qr code

A system for filtering detection patterns in a QR code, the system comprising:

• a pattern obtaining module, for obtaining a plurality of patterns to be detected;
• a pattern side length determining module, for determining a side length for each pattern to be detected;
• an average value obtaining module, for determining an average value of the side length of the plurality of patterns to be detected according to the side length of each pattern to be detected;
• a reference value determining module, for determining a reference value for the detections patterns according to the average value and the side length of each pattern to be detected;
• a detection pattern determining module, for comparing the side length of each pattern to be detected with the reference value, and determining patterns to be detected that meet a predetermined condition as detection patterns.

A system for filtering detection patterns in a QR code, the system comprising:

• a processor, wherein the processor is configured to
• obtain a plurality of patterns to be detected;
• determine a side length for each pattern to be detected;
• determine an average value of the side length of the plurality of patterns to be detected according to the side length of each pattern to be detected;
• determine a reference value for the detections patterns according to the average value and the side length of each pattern to be detected;
• compare the side length of each pattern to be detected with the reference value, and determine patterns to be detected that meet a predetermined condition as detection patterns.
