Realization For Decoder Of The 2-Dimention Code Based On The Use Of Cloud Computing

With the 3rd Generation licenses allocated to the mobile operators and the large input for 3G, mobile internet has been developing rapidly. State at the end of the first half year of 2010, the number of Chinese mobile phone internet user has get to 277 million,43.34million more compared to the number of 2009. The rising trend will accelerate as the 3G network's quick development.But the mobile internet has its inborn defects compared to the traditional internet. First, the terminal of the mobile internet has weaker computing ability on the business computing and the multi-media disposal compared to personal computers, so the applications it can deal with are very limited. Second, the bandwidth of the mobile internet is small than traditional internet. Although the 3G, WIFI can help to break through the bottleneck of the bandwidth, more and more applications' online will bring up higher requirement for the bandwidth. Cooperation with the Cloud computing is the future of the mobile internet.Cloud computing can bring the "computing" to the server side from the terminal side, so it bring down the requirement for the computing on the terminals, so it's useful for the applications'population. Then, Cloud computing weak the need for bandwidth. The user only need to get the necessary data from the server of cloud sides needn't all the data to be down load to the terminal. The last, Cloud computing can accelerate the speed of the computing, making the feeling of the application smoother.This paper is based on the use of the Cloud computing in mobile internet. Propose a solution based on the Cloud computing for the decoder of 2-dimention code, mainly for Quick Respond code. At last, complete the software for decoder.The main achievements of the research are as follows:1. Have a research for the using station of mobile internet, and have a conclusion of the characteristics, list the advantages of the Cloud computing using in mobile internet.2. Have a particular conclusion for the use of the Cloud computing, combined with the use of the mobile internet; bring forward the advantage of the use of Cloud computing in mobile internet.3. Brief introduction for the new application of 2-dimention code, and a research for the usages of it. Bring forward the solution used Cloud computing for the 2-demention application4. Have a deep research of coding principle for the QR code, and have a realization on the Android operating system. 5. Begin as the picture process, detailedly introduced the coding procedural. Complete a software use the Visual C++. The software can be replant on the Linux or the Windows operation easily.6. At last, the paper has done a test separately for the software under the mode of digitals, digitals plus characters, Chinese characters, Chinese characters plus digitals. The result completely comply with expect. The software also has a high recognize rate for the picture taken by the mobile phone.The content for the paper are as follows:The first chapter:Introduction to the background of the object, elaborate the advantage of Cloud computing using in mobile internet.The second chapter:Design a system for the QR decoder, including the research environment set up.The third chapter:Introduction to the Android operation system, and the coding theory of QR code, complete the of QR code generator on the Android system.The forth chapter:Introduction to the decode theory of the QR code; completing of the decoder of the QR code using Visual C++.The fifth chapter:Conclusion and prospect for the object.
