The present invention relates to a system and method for automatically identifying a QR code that may enable the automatic identifying and reading of one or more QR codes by capturing them once without the need to adjust a distance for identifying the one or more QR codes, when a user executes a QR code identifying application installed in a mobile terminal carried by the user. The device for automatically identifying a QR code according to an embodiment of the present invention is characterized in that it comprises: an image capturing unit capturing images of QR codes including identifying points and the surrounding views of the QR codes and acquiring surrounding images including the QR codes; a QR code identifying unit transforming surrounding images including QR codes acquired by the image capturing unit into grayscale images on a pixel basis, transforming the grayscale images into histograms representing a distribution chart according to brightness of each pixel, setting a candidate group of pixels by extracting, on the basis of the histograms, only pixels having brightness concentration levels corresponding to values exceeding a threshold, identifying identifying points by using the QR codes if three identifying points are conceived from the candidate group of pixels by an identifying marker, and reading information on the identified QR codes; a display unit displaying the identified QR code images or the read QR code information; and a storage unit matching and storing the identified QR code images with the read QR code information. |
