Abstract

For traditional QR code (Abbreviated from Quick Response Code) structure design, consists of black modules (square dots) arranged in a square grid on a white background, with this design, we can not put a large picture in QR code. It is not convenience if we want advertisement using QR code. We want to use a new method for QR code structure design, with this method, space in centeral of QR code area can be freed for user customization.

A new design patten of QR code

QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed for the automotive industry in Japan. A barcode is an optically machine-readable label that is attached to an item and that records information related to that item. The information encoded by a QR code may be made up of four standardized types ("modes") of data (numeric, alphanumeric, byte / binary, Kanji) or, through supported extensions, virtually any type of data.

A QR code consists of black modules (square dots) arranged in a square grid on a white background, which can be read by an imaging device (such as a camera) and processed using Reed-Solomon error correction until the image can be appropriately interpreted; data is then extracted from patterns present in both horizontal and vertical components of the image

Below is the structure of QR code, from it we can see, we can not put a large picture in QR code. It is not convenience if we want advertisement using QR code.

We have an idea of new QR code design patten, use this design pattern, all info will stored in frame area of QR code. Then we have enough space to put kinds of image. It will provide convenience for user.

QR code identification method

1. Use edge detection (Open CV algorithm) for QR code area recognization. Then we can know the position of square corners.

2. From and position of square corners, and according to...
