中文摘要
一维条码在生产和生活的各个方面得到了广泛的应用,极大的提高了生产率,但是一维条码本身的缺点:信息量小、依赖数据库等也日益的现露出来。二维条码本身具有高容量、高密度、纠错能力强、安全强度高等特点,使得二维条码作为信息的载体在信息自动化领域发挥着越来越重要的作用。QRCode作为快速响应二维码,以其独特的优势,在汉语国家发展迅速。目前,国内QR码的识别大多是基于PC的,Android平台上当前流行的二维码识别软件普遍存在着扫描速度慢,需要精确对焦等缺点。
该软件基于Android开发平台在windows环境下采用面向对象方法进行开发。首先,进行需求分析,绘制了用例图和活动图。然后,在概要设计中建立了系统功能模型,并在详细设计阶段对图片处理过程进行设计。最后,对软件进行编码和测试。该软件实现了二维码的扫描与识别,具有很强的实用性。

Abstract
One-dimension barcode is widely used recent years in all aspect of life, which greatly improved the productivity. However, the faults of 1-D barcode have e increasingly apparent, the information storage of it is so little, and also it must be rely on database. Two-dimension barcode has the characteristics of high capacity, high density, high security and good error correction ability, which make it play more and more important role in information and automation field. QRCode(Quick Response Code), as a 2-D barcode, develops rapidly in Chinese speaking countries with its unique advantages. At present, in our nation, recognition of QRCode mostly bases on PC, and the recognition speed and accuracy are not so good. Moreover, the popular barcode recognition software on android platform has some ings prevalently, such as slow speed of recognition, etc.
The development of the software is based on Android platform by object-oriented programming method under the Windows OS. Firstly, this paper describes the detailed demand analysis to draw use case diagram and activity diagram. Then constructing the system function model in general design, meanwhile, designing the details of diagram process. Finally, the software implements the scanning and recognition of two-dimensional barcode by decoding and testing, after that, this software has robust applicable ability.
