Reasearch And Implementation Of Real-View Navigation In Smart Library System

In china, driven by the rapid development of information technology, compus information technology developped quickly, and played a more and more important role in the process of reform and development of colleges and universities. Construction of mobile intelligent library service system has become the most important of the compus information technology. By smart library system, readers should not only be able to search books’information through app in smart phone, but also be able to find the searched book quickly and easily. Based on the characters of smart phone, the real-view navigation technology would get the phone’s derection, phone’s gesture through the terminal built-in electronic compass, accelerometer sensor, then real-view navigation technology project normal navigation routes on real view, using augmented reality. This thesis also proposed a point:we can appear the common map navigation and real-view navigation on the same screen. By this way, users can combine the maps and real views, so they could feel a new and more realistic way to know about navigation routes.At first, this thesis introduces about the background of the development of smart library. Secondly, the thesis introduces some techniques and priciples associated with real-view navigation system, such as the iOS programming technology, augmented reality technology, mapping technology and interaction between Objective-C and Javascript, etc. Further more, this thesis makes the smart library system (also called personalized library system) requirements analysis and system design, and do the requirements analysis and design of the real-view navigation in detail. The thesis also designs the system’s database. Next step, the thesis describes the system’s environment in both hardware and software.When introducing the implementation of the real-view system, firstly, the thesis describes both indoor and outdoor map navigation design process and the implementation principle, introduces data structures to achieve this fuction in iOS system. Then, the thesis describes how to get phones’gesture, how to calculate projection coordinates in the real-view navigation system. Further more, the thesis explains how to make navigation straights into navigation flats in real-view navigation system. Finally, through actual test, get the conclusions that this real-view navigation is feasible.In the end, we make a summary of this thesis, and point out the inadequecies and future wroks. Works and achievements during the master graduate study are summarized at the same time.
