Problems solved by technology

Due to the limitation of the radiation distance of radio waves, this method needs to install a certain density of base stations, and power supply is also a problem, so it is often used for indoor positioning, and it is rarely used in the wild
[0006] As for other indoor positioning methods, inertial navigation positioning will have cumulative errors, and it can only be an auxiliary means of other methods. Other methods either need to create a large amount of fingerprint data or rely on additional equipment to perform positioning

Embodiment 1

[0036] The embodiment of the present invention provides a mobile terminal map positioning method, such as figure 1 As shown, it is a flow chart of the mobile terminal map positioning method described in the embodiment of the present invention, and the method includes the following steps:

[0037] Step 1. Select at least two auxiliary positioning points near the point to be positioned P, that is, the distance from the point to be positioned is less than a preset distance threshold (set to 100 meters in this embodiment).

[0038] The auxiliary positioning point should meet the following requirements:

[0039] 1. There is no obstacle blocking the line of sight between the auxiliary positioning point and the point to be positioned.

[0040] 2. The point to be located is not located on the straight line where any two auxiliary positioning points are located. In this embodiment, there are two auxiliary positioning points, and then the two auxiliary positioning points and the point...

Abstract

The invention relates to a mobile terminal map positioning method, terminal equipment and a storage medium. The mobile terminal map positioning method comprises the steps of: S1, selecting at least two auxiliary positioning points within a certain distance around a to-be-positioned point; S2, aiming at each auxiliary positioning point by means of a mobile terminal after arranging the mobile terminal at the to-be-positioned point, and acquiring an azimuth angle of a straight line on which each auxiliary positioning point and the to-be-positioned point are arranged by means of an electronic compass of the mobile terminal; S3, drawing a straight line passing through the auxiliary positioning points on the map according to the azimuth angle of the straight line on which each auxiliary positioning point and the to-be-positioned point are arranged; S4, and taking coordinates of intersection points of all drawn straight lines as the coordinates of the to-be-positioned point. The mobile terminal map positioning method depends on an existing electronic map, aims at two or more known points on the electronic map, measures the azimuth angles of the known points, draws the straight lines, positions the current point by means of a plane angle measurement intersection method, and achieves precise positioning.

Description

technical field [0001] The invention relates to the field of electronic map positioning, in particular to a mobile terminal map positioning method, terminal equipment and a storage medium. Background technique [0002] With the rapid development of information technology and the Internet, mobile terminals have gradually become popular, and smart phones will fully replace traditional feature phones in the near future. In order to facilitate work and life, people have installed positioning chips and software such as map APPs on smart terminals to achieve positioning and navigation. Commonly used field positioning methods include base station positioning, GNSS positioning, wireless positioning, and indoor positioning methods include wireless communication, base station positioning, inertial navigation positioning, image recognition positioning, fingerprint positioning, geomagnetic positioning, etc. [0003] The base station positioning uses the position saved by the communicat...
