Distortion Correction of a Quick Response Code Image

Abstract:

Distortion typically occurs when images are captured from the surface of a cylindrical object. This problem is obvious in Quick Response (QR) code images, which necessitate distortion correction for subsequent information reading. Based on a detailed analysis of this distortion, we divided it into linear distortion along the generatrix direction and curl distortion perpendicular to the generatrix direction, and proposed a unified method to correct the distortion of both components. Experimental results are given to demonstrate the feasibility and applicability of the method.
