Abstract

The invention relates to the technical field of navigation, in particular to an immersive navigation system of a mobile terminal based on augmented reality and satellite positioning . The system comprises an outdoor augmented reality navigation system and an indoor augmented reality navigation system. In an outdoor environment, the system converts a satellite positioning coordinate and a point-of-interest coordinate into a virtual coordinate, and finally puts a virtual road sign and a virtual route on a real road by using an augmented reality technology, thereby achieving an effect of virtual-real fusion. In an indoor environment, the system integrates indoor map information acquisition, indoor navigation positioning and augmented reality navigation functions, regional positioning is realized by using a WiFi fingerprint matching positioning algorithm, and high-precision indoor positioning is realized by combining a visual matching positioning method.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to an immersive navigation system based on mobile terminal augmented reality and satellite positioning. Background technique [0002] With the rapid development of the Internet and smart phones, location-based services are becoming more and more popular, and the demand for navigation is also increasing. In recent years, with the rapid development of AR technology, the combination of augmented reality technology and location-based services (LBS) has become a research hotspot. Using augmented reality technology, users can travel in an intuitive way of navigation, which greatly improves the efficiency of navigation. Solve the problem that users find it difficult to find the target building during navigation, and effectively make up for the shortcomings of traditional navigation methods. Contents of the invention [0003] In view of the above-mentioned shortcomings existing in th...
