优秀毕业论文 精品参考文献资料 Design and Implementation Of The Mobile Indoor Location and Navigation System Based on Android Platform Abstract With the development of wireless communication network, smart phones had gradually integrated into peoples daily lives, which meet not only the needs of basic functions for users such as making a phone call, sending a message, but also the users demands for entertainment, surfing the Internet and socializing. Besides navigation function has been commonly utilized, however the navigation function nowadays is based on GPS (Global Positioning System) in the outdoor environments whereas a number of applications need to navigate indoors. This article designs and implements the Indoor Location and Navigation System based on the Android platform. Firstly, this article makes an introduction to the Android platform, mainly introducing four core components of Android and the Intent component on the basis of detailed the introduction to the architecture of Android and its core function module in detailed. Secondly, this article makes a detailed introduction to the Mobile Indoor Location and Navigation System Based on Android Platform. The system consists of three modules: 1, Pedometer Module: Pedometer module is the most basic function of the navigation system. Acceleration sensor is the data source which is utilized to implement such function; 2, Heading Determination Module: To determine the heading direction is another basic function of the indoor navigation system. Smartphone coming with a gyro sensor can be used to implement the judgment of the direction, but as a result of perception errors and the attitude of the phone itself swing down the accuracy of the measurement drops down. This article uses the PSP algorithm to process the gyroscope’s data and improves the accuracy of the pedestrian tracking; 3, Display Module: The indoor map illustrates the real-time routes via View components and SQLiteOpenHelper components of the Android development
