It is understood that these embodiments are given solely for the purpose of enabling those skilled in the art to better understand and to practice the invention, and are not intended to limit the scope of the invention in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Accordingly, the present disclosure may be embodied in the form of: entirely hardware, entirely software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
According to the embodiment of the invention, an optimization processing method and system for two-dimensional code scanning and recognition are provided, and the method and system relate to the technical field of two-dimensional code scanning and recognition. The optimization processing process comprises the following steps: setting a decoding format, and mainly aiming at two most main formats, namely QR Code and Code 128; the decoding algorithm is optimized, the recognition speed is higher, and the recognition precision of the low-resolution image is higher; cutting invalid decoding data, cutting useless areas and reducing the data amount of decoding; the camera frame parallel processing mode is set, so that the two-dimensional code detection speed can be greatly increased; setting camera parameters, selecting the optimal preview size/picture size, and improving the identification precision; the amplification factor setting module is arranged, so that the problem of adaptation of the mobile phone is perfectly solved; and setting a focusing strategy, and increasing the analysis frequency by adopting a continuous focusing mode, so that the analysis frequency is increased by shortening the focusing time, and the code scanning performance is improved.
In the embodiments of the present invention, terms to be described include:
two-dimensional code: the coding mode widely used on the mobile equipment can store more information and represent more data types than the traditional Bar Code Bar Code;
QR Code: a matrix two-dimensional code symbol has the advantages of large information capacity, high reliability, capability of representing various character information of Chinese characters and images, strong security and anti-counterfeiting performance and the like of a one-dimensional bar code and other two-dimensional bar codes.
Code 128: one high density barcode, CODE128 CODE, can represent 128 characters from ASCII 0 to ASCII 127, and is called 128 CODE. Including numeric, alphabetic, and symbolic characters.
Zbar: the zbar algorithm is a bar CODE which is open on the internet at present, and is a two-dimensional CODE detection algorithm, and the algorithm can identify most kinds of one-dimensional CODEs (bar CODEs), such as I25, CODE 39 and CODE 128.
ZXing: ZXing is an open source, 1D/2D barcode image processing library implemented in Java in a variety of formats, which contains ports for linking to other languages. ZXing can realize that the built-in camera of the mobile phone is used for scanning and decoding the bar code.
ZXing provides two binarization algorithms in total, one is a hybrid Binarizer, and the other is a GlobalHistogramBinarizer;
