Embodiment

[0033] A method for drawing a WiFi fingerprint map, the process comprising:

[0034] Step (1): generate an empty database in the map data server;

[0035] The database is used to store the plan information of the target area, the coordinate data of the calibration point and its corresponding WiFi fingerprint data information.

[0036] Step (2): Draw the client offline through the WiFi fingerprint map, manually import the planar map of the current area to be tested, and carry out reasonable calibration;

[0037] Step (3): according to calibration point, repeatedly measure its corresponding WiFi fingerprint information point by point;

[0038] Step (4): the position of the calibration point and its corresponding WiFi fingerprint information are filled in the empty database corresponding to the current area plan to be measured;

[0039] Step (5): Read the database, render the plan with the WiFi fingerprint information and send it to the online positioning client, so as to reali...

Abstract

The invention discloses a method and a system for drawing a WiFi fingerprint map. The method comprises the following steps: generating an empty database in a map data server; drawing a client offline through a WiFi fingerprint map, manually importing a planar graph of a current to-be-detected area, and carrying out the reasonable calibration; according to the calibration points, measuring the corresponding WiFi fingerprint information point by point for multiple times; filling the position of the calibration point and the WiFi fingerprint information corresponding to the calibration point into an empty database to correspond to the planar graph of the current to-be-detected area; reading the database, rendering the planar graph with the WiFi fingerprint information, and transmitting the rendered planar graph to an online positioning client, thereby realizing a WiFi indoor positioning function of a drawn map area.

Description

technical field [0001] The invention relates to the field of indoor positioning technology map drawing, in particular to a method for drawing a WiFi fingerprint map and a system thereof. Background technique [0002] In the WiFi indoor positioning technology, it is divided into two stages: offline data collection and online data matching. If you want to carry out WiFi indoor positioning on the target area, you need to calibrate and collect the fingerprint points of the target area first. When offline collection is performed manually, due to the large area and irregular shape of the collection area, the collection work has a certain degree of professionalism. It is impossible to outsource such complicated and disorderly collection work to non-technical personnel, wasting a lot of professional human resources. In addition, there is no systematic WiFi fingerprint map drawing scheme, which also makes the data collection work of experimenters confusing and inefficient. Contents...
