Design And Implementation Of A Lbs-Based Mobile Applications Of Augmented Reality Technology

With the development of smart handheld devices, the concept of things to show more clearly. Introduction of smart devices in the direction of the sensor, GPS, light sensors and other sensor devices,"ubiquitous computing" concept has become more practical guidance value, coupled with the development of location-based services rapidly, based on augmented reality technology will have a huge LBS market prospects. On this basis, the design of geographic information release platform, using sensor devices, smart terminal extensions on the Android augmented reality functionality, integration and virtual reality scenes information, complete LBS prototype system based on Web services.In this paper, the LBS system based on augmented reality technology consists of five modules, such as network communication services, data storage module, terminal information acquisition module, points of interest (POI) identification module and UI interactions module. Network communication service module using asynchronous HTTP request service ensure the main UI thread is not blocked; data storage module provides the management of the local SQLite database and image cache; Location Services API module uses the Android system provides information on GPS location services Sign up monitoring, the system provides a high degree of latitude and longitude information accurate; UI module provides interactive display of LBS-based augmented reality features and multi-threaded rendering Surfaceview picture view function. Finally, take " Charming Wuxi " for example, demonstrate enhanced levels of LBS application scenarios reality system.
