Problems solved by technology

Since the outdoor positioning signal and the indoor positioning signal are both weak in indoor and outdoor boundary areas, it may not be possible to achieve independent positioning. Therefore, even if the positioning signal is switched, the stability and quality of the positioning signal in this area cannot be guaranteed. The traditional positioning solution cannot realize the seamless switching of indoor positioning

Embodiment Construction

[0057] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0058] At present, LBS has penetrated into the national economic fields such as transportation and logistics and people's daily life, and is quietly changing people's production and lifestyle. As the basis of LBS, positioning technology occupies an extremely important position. Public safety, production safety, emergency rescue, public health, Internet of Things, special population monitoring, large venue management, smart city construction, etc. all need to use sufficiently accurate positioning information. However, in indoor environments such as supermarkets, hospitals,...

Abstract

The present application relates to a method, a device, a computer device and a storage medium for seamless switching between indoors and outdoors. The method includes: determining the current positioning sub-area of ​​the mobile terminal from a plurality of pre-divided positioning sub-areas; the multiple positioning sub-areas include at least an indoor positioning area, a positioning boundary area and an outdoor positioning area; The corresponding relationship between the positioning sub-area and the positioning mode determines the positioning mode corresponding to the positioning sub-area where the mobile terminal is currently located; the indoor positioning area and the outdoor positioning area correspond to the first positioning mode and the second positioning mode respectively; the positioning mode corresponding to the positioning junction area The first positioning method or the second positioning method is fused with the inertial navigation; the positioning method corresponding to the positioning sub-area where the mobile terminal is currently located is used to locate the mobile terminal. The method can realize the integration of indoor and outdoor positioning, and ensure the stability and fluency of positioning signals.

Description

technical field [0001] The present application relates to the technical field of positioning and navigation, and in particular to a method, device, computer equipment and storage medium for seamlessly switching indoor and outdoor positioning. Background technique [0002] With the development of wireless communication technology and satellite navigation technology, Location Based Service (LBS) has become an important part of modern social life and production. The Global Positioning System (GNSS) has been able to meet the positioning needs of the outdoor environment and is becoming more and more mature, such as the Global Positioning System (GPS) in the United States, the Global Navigation Satellite System (GLONASS) in Russia, and the Global Navigation Satellite System (GLONASS) in China. Beidou system. However, the satellite positioning system lacks indoor positioning capabilities, cannot meet public needs, and has a "last mile" bottleneck. At present, in order to meet the...
