Zusammenfassung:Two-dimensional code has shown its impressive performance on mobile payment and advertising marketing. To ensure that the two-dimensional code is correctly identified by recognition devices, the traditional two-dimensional code must be attached to the surface of plane. However, if the code attached to the surface of cylinder or prism carrier, the image of the normal two-dimensional code will be distortion because of image projection, which will lead to identification problem. To this end, we propose a novel approach of design and identification of anti-distortion two-dimensional code on prism and cylinder combination surface based on pre-stretching, to address the challenge of identifying a two-dimensional code on prism and cylinder combination carrier. According to the spatial geometric relation of the two-dimensional code carrier, pre-stretching the normal two-dimensional code image via inverse mapping to obtain the pre-deformed two-dimensional code that will be printed and then pasted on the surface of the carrier. Specifically, the image of the pre-stretched two-dimensional code in the projection plane of the acquisition device is just as the normal two-dimensional code, which will be correctly identified. Experimental results show that the two-dimensional code after pre-stretching could be identified by normal recognition devices.
