A positioning method and terminal

Abstract

The embodiment of the present application discloses a positioning method, which is used to improve the accuracy of terminal positioning. The method in the embodiment of the present application includes: the terminal obtains the first positioning result according to the first signal and the preset fingerprint database matching; the terminal determines the location feature of the terminal according to the location feature information and preset conditions, and the location feature information Including changes in at least one second signal within a predetermined period of time; the terminal matches in a map database according to the first positioning result and the location feature, and obtains a second positioning result, and the map database includes position A correspondence between features and map positions; the terminal determines the position of the terminal according to the second positioning result. The embodiment of the present application also provides a terminal.

Description

technical field [0001] The application relates to the computer field, in particular to a positioning method and terminal. Background technique [0002] With the popularization, generalization, and dailyization of location-based services, location-based services have become an increasingly indispensable basic demand for people. Most of people's daily activities are indoors, and most of the terminal use and data connection are also indoors, and people's daily activity information is usually related to location and time. Therefore, the demand for location-based services in the mobile Internet era will become more and more bigger and bigger. [0003] There is an existing method for indoor positioning using terminal sensors. The application scenario is when the initial position is unknown or the line of sight is blocked. Based on the amplitude of the geomagnetic signal, the dynamic time warping (DTW) algorithm is used to match the geomagnetic fingerprint database. In this way, ...

Problems solved by technology

[0004] However, this method mainly relies on the magnitude of the geomagnetic signal to identify features such as indoor corridors and pillars, and electrical equipment in the surrounding environment (such as refrigerators, servers, etc.) is likely to interfere with the strength of the geomagnetic signal received in real time, resulting in a matching location. Prone to error, the positioning position of the output is not accurate
