Indoor and outdoor full-directional positioning method

Abstract

The invention discloses an indoor and outdoor full-directional positioning method. The method comprises the following steps: acquiring a position coordinate signal of a user by utilizing a Beidou positioning module; acquiring acceleration and the acceleration direction of the user by utilizing an inertial navigation device; acquiring a current elevation position of the user by utilizing a GPS elevation positioning module, and combining the data to determine three-dimensional positioning of the user; combining image information of a three-dimensional map library, and pushing the positioning position to a display screen. By adopting the method, through a combined means of Beidou positioning, inertial navigation positioning and GPS positioning, indoor and outdoor full-directional precise positioning can be realized; meanwhile, a data interconnection function can be realized by combining the positioning means with mobile phone APP and cloud end backstage, so that application and development of a positioning technology and an IOT (Internet of Things) technology can be pushed, and convenience for the life of people is provided.

[0003] Chinese patent application number 201110006182.X discloses a GPS-based navigation and positioning deviation correction method and device, which calculates the current travel direction and road direction by receiving the current positioning point obtained by the global positioning system However, this system is suitable for vehicle navigation. When entering the room, the navigation cannot normally perform positioning.

[0004] Chinese patent application No. 201610443366.5 discloses a LED indoor positioning and navigation method and positioning and navigation system. It uses LED lights as the transmitting terminal, and the driving device at the transmitting end controls the intensity of the current to cause light and dark changes to transmit Physical position data realizes indoor positioning. However, this positioning method must first arrange LED positioning auxiliary light sources, and the application limitations are relatively large.

[0005] Chinese patent application number 201010200943.0 discloses a navigation system and a navigation method, which realizes the navigation and positioning function through a global positioning device, a map information database, an active area recorder, and an image processing unit. However, in this system It does not have the ability to judge the altitude position, so it cannot achieve all-round positioning
