Embodiment Construction

[0027] The indoor and outdoor integrated positioning system of the present invention includes a cloud server, a mobile device, an inertial navigation device and an inertial navigation starting positioning pad;

[0028] The cloud server is used to create a map, and the buildings in the map are 3D images, and the 3D images are used for indoor positioning;

[0029] Specifically, the method for establishing the 3D image is shown in the appendix. figure 1 shown, including the following steps:

[0030] S01. Create the outline of the base of the building on the map;

[0031] S02. Set the floor height and number of floors of the building;

[0032] S03. Based on the outline of the base, generate a 3D map with the floor height and the number of floors.

[0033] In addition, when creating a 3D map, in order to improve the overall display effect of the map, the floor height of the building is scaled up or down, and different floors are distinguished by different colors.

[0034] The i...

Abstract

The invention discloses an indoor and outdoor integrated positioning system and method, and relates to the technical field of positioning. Indoor positioning is realized by creating a map on a cloud server, setting a building in the map into a 3D map, positioning outdoors by using a GPS, and positioning by combining inertial navigation equipment with the map when a user enters a room; the problem of how to realize indoor and outdoor integrated positioning is solved, meanwhile, during indoor navigation, a 3D map can be established on site for a building needing to enter through a mobile device, indoor navigation can be realized, the problem that existing indoor positioning cannot be started quickly is solved, and due to the fact that the inertial navigation device and the map are combined for positioning, the positioning accuracy is improved. When indoor positioning equipment is damaged, only the position of the inertial navigation coordinate system in the map needs to be ensured, so that only the inertial navigation initial coordinate positioning pad needs to be used for assistance, the problem that positioning cannot be realized when the indoor positioning equipment is damaged is avoided, and the method is suitable for indoor and outdoor integrated positioning.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to an indoor and outdoor integrated positioning system and method. Background technique [0002] With the development of the times, in the past three decades, the global satellite navigation system represented by GPS has reshaped human life and has become an important technological milestone in modern society. Location services play a key role in everything from map navigation to social networking. More and more skyscrapers, shopping malls, transportation hubs, stadiums, and medical centers are becoming new landmarks in the city. These modern large buildings, without exception, have a huge amount of interior space. [0003] The widespread use of smartphones and other wireless devices has directly detonated the market demand for indoor location data. However, GPS cannot provide reliable location data in indoor conditions due to non-line-of-sight communication issues. ...
