Abstract

The invention discloses a three-dimensional wireless positioning navigation system, which is characterized by comprising a map module, a navigation module, a positioning module and a system hardware module, wherein the map module is mainly used for completing downloading of an electronic map and an analysis function of the electronic map to prepare for the navigation module and the positioning module; the navigation module is used for computing a navigation path according to a current position and a target position which are input by a user; the hardware module comprises an acceleration sensor, an electronic compass and a WiFi receiver; the positioning module is capable of implementing a corresponding positioning algorithm according to the information of the hardware module and the navigation module so as to complete a positioning function of the positioning module. The three-dimensional wireless positioning navigation system has the following beneficial effects that in comparison with the prior art, the problem of incapability of carrying out indoor positioning by the existing outdoor navigation technology is solved, and the precise navigation is implemented under the complex indoor scene; in comparison with the exiting indoor positioning technology, an error is smaller, and an efficient and accurate navigation path is provided for the user under the complex indoor scene.

Description

technical field [0001] The invention relates to the field of navigation systems, in particular to a three-dimensional and wireless positioning navigation system. Background technique [0002] With the advent of the era of rapid development of information technology, indoor positioning and navigation technology plays an important role in more and more applications. Although the global satellite positioning system (GPS) has excellent positioning performance in outdoor environments, it is not suitable for indoor environments. Because GPS satellite signals cannot penetrate too thick walls, navigation equipment will not be able to locate satellite signals completely in large buildings, underground buildings, and high-rise buildings. Indoor positioning has become the focus of research and development of positioning technology. [0003] Indoor navigation and positioning technology can bring great convenience to people's life and work. Portable devices such as touch screens, mobil...
