Indoor navigation method based on combination of region location, inertial navigation and map path

Abstract

The invention discloses an indoor navigation method based on the combination of region location, inertial navigation and map path. The indoor navigation method comprises the following steps: S1, region identification location; S2, inertial navigation; S3, map path data aided navigation. According to the invention, the indoor navigation method heavily relies on sensor data and map path data of a terminal and less relies on wireless signals, so that the laying and maintenance costs are greatly reduced; meanwhile, the location and navigation technology for cooperating the sensor data, the map path data and the wireless signals greatly improve the accuracy of indoor location and navigation.

Description

technical field

[0001] The invention relates to a navigation technology, in particular to an indoor navigation method based on area positioning combined with inertial navigation and map paths. Background technique

[0002] There are many types of existing indoor positioning and navigation technologies. From the positioning principle, there are mainly identification code (ID)-based positioning methods, geometric positioning methods, and fingerprint positioning methods. The positioning method based on the identification code (ID) identifies the user terminal by identifying the ID of the access point, such as WiFi wireless access point, or various signal sources such as Bluetooth signals, combined with the indoor location corresponding to the preset access point ID location, but the positioning system depends on the density of access points. If higher positioning accuracy is required, a high density of access points is required, which increases the cost of hardware deployment a...
