Research and Application of Indoor Guide Based on Mobile Augmented Reality System

In view of the low precision and poor interaction in current traditional indoor navigation system of digital map, this paper puts forward an indoor guide strategy, which combines WiFi positioning technology with mobile AR technology. At the same time, the traditional natural feature extraction algorithm is improved by combining FASE with SURF. FAST-SURF can meet the requirement of robustness and real-time performance. A new mobile AR indoor guide system is designed and implemented in the digital museum based on the Android platform. Experiments show that the system has better practicability and broad application prospects with high precision of positioning and matching, good real-time performance and high precision of positioning navigation.
