Research And Implementation Of Augmented Reality Library System Based On Personal Service

Campus library has been an important method for students to acquire knowledge and improve themselves. With the rapid development of information technology, related technologies and applications of intelligent terminal are also emerging in mobile internet and many domestic and international libraries take the opportunity to launch a library application related with book-searching business. But the traditional book-searching service can not meet the needs of readers to retrieve books quickly, locate books and other aspects of personalized services in many ways, which presents a greater challenge for the library to meet the user’s needs. The topic of research and implementation of library personalized service based on augmented reality, is to build an application which combined cutting-edge technology of mobile internet with data mining services, and provide readers with a range of traditional books search and a series of personalized location-based services book reading and book recommendations.This thesis introduces the research background at first, then detail the issues associated with the related technologies such as augmented reality, sensor principle and ios development framworks and gives a detailed description of3D registration principle based on sensor-based and vision-based augmented reality technology. Then it demonstrates the whole platform implementations of existing technologies and users’needs analysis, at last describes the hardware and software system implementation environment.In the design and implementation of the system, the system architecture description is divided into server-side and mobile terminal. The server provides LBS relevant services and book searching support with concrete description of the underlying data model and web service interface implementation. According to the MVC design ideas, the concrete realization of mobile client application details the view layer, the model layer and controller layer. Then achieves a detailed description of personalized services including:real-time two-dimensional code scanning, real-time calculation of the projection matrix, the projection of three-dimensional objects and location-based library book searching and recommendation function.Finally, the thesis describes the detailed functional testing of the whole system. The test results show that the application can provide the reader with location-based services related books reading books and personalized recommendation services by way of scanning two-dimensional code. Then the summary analyzes the shortcomings in the existing part of the system design, and points out the direction for the future study.
