Design And Implementation Of Changsha Bus Navigation System Based On Augmented Reality

With the continuous development of mobile terminals,while GPS is continually permeating into smart phones,a variety of applications based on GPS positioning has become increasingly diverse,including mobile map application.In a variety of mobile applications electronics market,electronic map application downloads are in the forefront.In today's highly developed Internet,people have not been satisfied with traditional map single query.The future real three-dimensional geographic information services based on intelligence and sharing features will be the mainstream of the industry.This paper analyzes and studies the Android system architecture,application components,the relevant functional classes and the building processes of Android development platform.Then analyzes and studies the related theory of Changsha tourist bus involved in navigation applications,including the key technology of augmented reality,GPS location,compass and gyroscope,in which Augmented Reality technology mainly consist of display technology,tracking technology and AR registered development tools.On this basis,in the context of augmented reality technology we study the related technology,and develop a tourist photo navigation application based on the Android platform at the entry point on bus.And the entire function applications were analyzed,including six functional modules:Sign functional modules,information inquiry function module,path planning function module,two-dimensional navigation module,photo navigation module and data collection module.And separately conducts storage design,functional design and interface design to each module.Storage design needs to be stored in the database which is mainly responsible for the data storage module,query,modify functions;functional design of each functional module was designed to run flowchart;interface designed is used to design user interface for various functional modules.To some extent,this study uses a number of successful examples for reference in the country.And based on the above work,we use augmented reality technology to design and implement a simple sightseeing bus system that can satisfy the needs of users based on the Android platform.
