Problems solved by technology
However, the way of manual collection is limited by the labor cost, and the fingerprint data that can be collected is limited
In this way, the positioning accuracy of the established positioning database is also low.

Embodiment Construction
[0083] The implementation of this embodiment will be described in detail below in conjunction with the accompanying drawings.
[0084] With the emergence of large indoor places (eg, large hospitals, large shopping malls, etc.), users' demand for indoor positioning services also increases.
[0085] However, due to the influence of building walls, when a user in an indoor location uses a conventional positioning technology (such as a satellite positioning technology) to perform positioning, problems such as positioning drift are prone to occur. In order to improve this problem, indoor positioning technology came into being. Wherein, the difference between the indoor positioning technology and the satellite positioning technology lies in that a corresponding positioning database needs to be established in advance to realize the indoor positioning technology.
[0086] The above positioning database may include multiple location points and corresponding fingerprint data in the ind...

The invention provides a method for creating a positioning database and electronic equipment, and relates to the technical field of positioning. The problems that fingerprint data for creating the positioning database is insufficient and the precision of the positioning database is insufficient are solved. According to the specific scheme, a first device receives first crowdsourcing data from each second device; the first device determines a first coordinate of the first track point in a preset coordinate system; the first device calibrates the distance and direction of the second track point relative to the first track point according to the first coordinate of the first track point; the first device determines a second coordinate of the second track point in the preset coordinate system according to the first coordinate and the calibrated distance and direction; and the first device constructs a positioning database according to the first coordinate, the second coordinate and the fingerprint data corresponding to the first track point and the second track point respectively.
Description
technical field [0001] The present application relates to the technical field of positioning, and in particular to a method for creating a positioning database and electronic equipment. Background technique [0002] With the emergence of large indoor places (eg, large hospitals, large shopping malls, etc.), the market demand for indoor positioning services also increases. Of course, the prerequisite for realizing the indoor positioning service is to establish a corresponding positioning database. [0003] In related technologies, when establishing a positioning database, professionals are required to collect fingerprint data at designated locations, for example, fixed-point collection of wireless fidelity (Wi-Fi) signals or Bluetooth signals, so that each fingerprint data corresponds to a designated location The absolute coordinates of the point. However, the way of manual collection is limited by labor costs, and the fingerprint data that can be collected is limited. In ...
