Problems solved by technology

But it is not difficult for us to see the shortcomings. The inertial navigation application of the step counting method still has certain limitations. When the device is located in other mobile devices (such as vehicles), the inertial navigation of the step counting method will not work; although the above method Indoor positioning and motion trajectory display can be achieved, but indoor path guidance cannot be further realized; therefore, the existing technology still needs to be improved

Abstract

The invention discloses an indoor positioning and path leading method based on mobile terminal inertial navigation. The indoor positioning and path leading method comprises the following steps: firstly collecting indoor path trajectory data in a subsection manner; performing optimizing processing on history path trajectory data by using a shortest path algorithm to obtain optimal path trajectory data; storing the optimal path trajectory data and uploading the stored optimal path trajectory data to a database; when a place of arrival is set by a user, obtaining corresponding most optimal path trajectory data from the database by mobile equipment, and performing path display and guidance. No extra equipment is needed, indoor inertial navigation and path guidance with relatively high precision can be achieved by just utilizing a built-in sensor of the mobile equipment, and the method has the characteristics of high practicability, high universality and low cost.

Description

Technical field [0001] The invention relates to an indoor positioning and path guidance method, in particular to an indoor positioning and path guidance method based on inertial navigation of a mobile terminal. Background technique [0002] With the rapid economic growth, there are more and more large indoor venues, such as shopping malls, airports, and museums. Aiming at how to facilitate people's shopping in large shopping malls and quickly find the entrance and exit of the airport, indoor positioning and route navigation are currently one of the hot spots of research. [0003] The main application of inertial navigation technology is to use the built-in gyroscope, acceleration sensor and direction sensor of the mobile device to realize indoor positioning. Inertial navigation technology has many outstanding advantages compared with other indoor positioning technologies (such as ultrasonic positioning technology, infrared positioning, WIFI positioning, etc.) because it does not r...
