Rail transit indoor and outdoor integrated navigation method and device, equipment and storage medium

Abstract

The invention relates to a rail transit indoor and outdoor integrated navigation method and device, equipment and a storage medium, and belongs to the technical field of communication navigation positioning and position service, and the method comprises the following steps: constructing an indoor and outdoor integrated space-time coordinate system; fusing a BIM model and a GIS platform based on the indoor and outdoor integrated space-time coordinate system to construct a three-dimensional indoor and outdoor real scene model; constructing the indoor and outdoor integrated path network based on the three-dimensional indoor and outdoor real scene model; and performing optimal path planning based on the indoor and outdoor integrated path network. The method has the effect of realizing high-precision indoor and outdoor integrated navigation suitable for urban rail transit.

Description

technical field [0001] The present application relates to the technical field of communication, navigation, positioning and location services, and in particular to a rail transit indoor and outdoor integrated navigation method, device, equipment and storage medium. Background technique [0002] With the rapid development of social economy, people's requirements for travel convenience have also increased. Therefore, urban rail transit has also developed rapidly. Common urban rail transit includes subway, light rail, etc. The surrounding environment of the station is generally more complicated, and the spatial structure inside the station is also quite complicated. Passengers who are not familiar with the complex internal and external environment of the station need an integrated indoor and outdoor positioning and navigation method for urban rail transit if they want to quickly enter and exit the station, take a train, and transfer. [0003] At present, related technologies a...

AI Technical Summary

Problems solved by technology

[0003] At present, related technologies are mainly used in a relatively broad indoor space, and there is no integrated indoor and outdoor navigation for urban rail transit, and it is difficult to meet the needs of passengers for positioning and navigation services in complex urban rail transit environments

At the same time, the indoor navigation and positioning of the current refined model lacks path planning factors. The selected data set only considers geometric information and does not have rich semantic information. Therefore, obstacle information is often ignored, resulting in low navigation accuracy.
