Problems solved by technology

WIFI fingerprints need to draw a "signal field strength map" (fingerprint library). The longer the signal collection time, the more collection points, the more accurate the fingerprint library, but the higher the time cost and cost
On the other hand, limited by manual operation, WIFI fingerprint collection and positioning can only be carried out on two-dimensional ground, lacking three-dimensional space processing capabilities

Abstract

The invention relates to the technical field of wireless communications, and in particular to an airship based three-dimensional WiFi (Wireless Fidelity) fingerprint drawing system and method. The method comprises the steps of mounting a WiFi positioning module and a WiFi fingerprint collection module on an airship; mounting a plurality of AP (Access Point) control points at key positions; carrying out real-time communication with a background positioning server; dynamically acquiring space-time information of the airship to realize navigational flight based on a spatial position and a route; dynamically collecting WiFi signals in the process; synchronously recording a temporospatial four-dimensional coordinate and a movement locus; integrally inputting the data into a GIS (Geographic Information System) module; automatically drawing an indoor (outdoor) three-dimensional WiFi map. Aiming at the problems of too much overhead, insufficient expansibility and the like of existing WiFi fingerprint matching positioning training, WiFi fingerprints are automatically collected by using a barrier-free positioning airship, the problems of long construction time, complex treatment, insufficient information, unfavorable maintenance and the like are solved, the construction and updating of the fingerprint map are accelerated.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an airship-based three-dimensional WiFi fingerprint mapping system and method. Background technique [0002] As a widely used suspended aircraft, the airship has the ability to suspend in the air, and the operation and driving are simple and convenient. It can fly at low altitude and low speed, and has relatively good safety performance. , easy to maintain. The advantage of indoor (outdoor) aircraft lies in its commercial value. It can be widely used in monitoring, mapping, positioning, communication, signal enhancement, and cargo transportation. It can provide a good peripheral vision and can be used for advertising display, aerial photography, TV broadcast and security monitoring and other activities. [0003] The WiFi fingerprint (Fingerprint) positioning principle is to establish a stable mapping relationship between WIFI signal features and location informat...
