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

Abstract

The invention relates to an indoor and outdoor seamless switching and positioning method and device, computer equipment and a storage medium. The method comprises the following steps: determining a current positioning sub-region of the mobile terminal from a plurality of pre-divided positioning sub-regions, wherein the plurality of positioning subareas at least comprise an indoor positioning area,a positioning boundary area and an outdoor positioning area; determining a positioning mode corresponding to the current positioning subarea of the mobile terminal according to a preset correspondingrelationship between each positioning subarea and the positioning mode, wherein the indoor positioning area and the outdoor positioning area respectively correspond to a first positioning mode and asecond positioning mode, and the positioning mode corresponding to the positioning boundary area is an inertial navigation fusion first positioning mode or a second positioning mode; and positioning the mobile terminal by adopting a positioning mode corresponding to the current positioning subarea of the mobile terminal. By adopting the method, indoor and outdoor positioning integration can be realized, and the stability and fluency of positioning signals are ensured.

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...
