AR Navigation Application based on iOS Platform

In this paper, an Augmented Reality Navigation Application based on iOS platform is designed. This application is composed of five modules: the Location Module, the Digital Map Module, the Approximate Module, the Estimate Module and the AR Module. The Location Module requests current location via GPS in real-time and obtains the details of destination from map server. The Digital Map Module provides a Satellite Imagery View which superimposes navigation routes with marks such as current location, starting and destination. The Approximate module produced an approximation to fix the bias when converting the geographical coordinates between WGS-84 and GCJ-02 system. The Estimate Module produced a 3D position estimation according to a geographical coordinate provided by GPS or map server. This estimation will be used for placing the marks and routes in AR view. The AR Module provides an Augmented Reality scene superimposed destination and the route on a real-world background with a real-world scale.
