An indoor and outdoor combined navigation method and system based on acquisition and positioning

Abstract

The invention discloses an acquisition and positioning based indoor and outdoor combined navigation method and system. The method comprises the following steps: acquiring an indoor and outdoor 3D map and a plurality of POI positions in the indoor and outdoor 3D map; detecting the coarseness positions of a track contributor and a navigation user in the indoor and outdoor 3D map; acquiring the personal motion track of the track contributor; extracting the effective motion track from the personal motion track according to the coarseness position of the track contributor in the indoor and outdoor 3D map and the plurality of POI positions in the indoor and outdoor 3D map, and storing the effective motion track; and receiving a navigation request of the navigation user, and generating a navigation path and sending the navigation path to the navigation user according to the coarseness position of the navigation user in the indoor and outdoor 3D map and the navigation request of the navigation user.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular, to an indoor and outdoor joint navigation method and system based on collection and positioning. Background technique [0002] The subway transportation system has been developed in more than 100 cities around the world, with a total length of more than 7,000 kilometers. Today, subways dominate the public transportation systems of many cities. For example, the Paris Metro system carries 70% of the Paris public transport ridership. [0003] When traveling by subway, passengers need a convenient and less time-consuming walking path from any indoor location of a subway station to a nearby outdoor destination—for example, a shopping mall. However, this basic requirement is not easy to satisfy for the following reasons. First, subway stations have complex indoor structures, especially for those transfer stations. Second, passengers do not know the situation of each entr...

AI Technical Summary

Problems solved by technology

Second, passengers do not know the situation of each entrance and exit of the subway station, especially when some exits extend into other indoor buildings, such as underground shopping malls

Therefore, they cannot realize indoor and outdoor automatic navigation

On the other hand, a lot of research efforts have been made to improve the accuracy of indoor positioning, yet indoor navigation systems have not been realized, let alone a joint navigation system from indoor to outdoor

[0005] For the lack of indoor and outdoor joint navigation technology solutions in the existing technology, there is no effective solution yet
