Abstract：When collecting the QR code image,the inclined or geometric distortion often occured.To solve this problem,a correction method combined the QR code feature,image rotation and image maps was pro-posed.This method,firstly,used the position detection patterns to detect tilt aberration after conventional image pre-processing and run length encoding;Secondly,selected the appropriate method by tilt aberration to correct the image;Thirdly,used grid and statistical methods to extract information and complete the deco-ding.The results showed that the method was simple and had a high rate of recognition.The computation of floating-point was small,so it could be used in embedded system.
