Research And Realization Of Indoor And Outdoor Augmented Reality Navigation

With the rapid development of the Internet and smart phones,location-based services are becoming more and more popular,and people are increasingly demanding travel navigation.Therefore,improving the user's navigation experience and providing more personalized location information services are people's urgent needs.In recent years,the rapid development of AR technology has made augmented reality and LBS become a hot research topic.In this context,this article separately researches outdoor and indoor augmented reality navigation,using the outdoor navigation data provided by the AMAP developer platform and the location data collected in the room,combined with the sensor position and position tracking technology,aiming at different outdoor and indoor environments.Designed and implemented an augmented reality navigation system based on Android platform:1)In the outdoor environment,the system is based on the integration of traditional AMAP services.Augmented reality navigation maps virtual landmarks into the real world,making the navigation process more intuitive and solving the problem that users can hardly find a kilometer away from their destination and destination.Finding directions and problems with target buildings can effectively compensate for the lack of traditional navigation methods.In the process of navigating to the surrounding points of interest,when the user's position and line of sight direction change,the virtual path also changes in real time,effectively improving the user's navigation experience,making full use of AR technology virtual objects mapped to the characteristics of the real world,and enhancing the mobile phone Navigation application fun.2)Indoors,the indoor augmented reality navigation system integrates indoor maps,indoor positioning,and AR navigation.Our AR method uses the WIFI-based location fingerprint database data,through the coordinate conversion and indoor azimuth calculation methods,to achieve enhanced display of indoor interest points to the camera video stream,to achieve the purpose of augmented reality navigation.We have done relevant experiments in the indoor environment of the Shenzhen University Teaching Building,and the experiment has achieved good positioning and navigation results.In this paper,the theory of sensor position tracking and the principles of coordinate transformation are first elaborated through theoretical derivation,and these principles are applied flexibly to outdoor augmented reality navigation.Then,on the basis of this,the point of interest data and path navigation data provided by the AMAP developer platform are introduced and integrated with the sensor data.Finally,the outdoor and indoor experiments were designed separately.Both outdoor and indoor can achieve better positioning and navigation results.The experimental results are compared with the traditional map navigation mode,which is more intuitive and interesting.
