Abstract
A positioning system and a positioning method based on WI-FI® fingerprints are provided. The method includes obtaining positioning map data; performing a clustering processing process to allocate collected data into reference groups in a target area according to collection coordinates; calculating metadata of WI-FI® access points; serving the metadata as a filtering condition related to an identification rate, and extracting WI-FI® fingerprint data with relatively high identification rate; establishing a machine learning model for estimating a relevant position based on the fingerprint data of the WI-FI® access points, and training the machine learning model with extracted WI-FI® fingerprint data and corresponding spatial coordinates to generate a trained machine learning model; configuring a communication module to receive WI-FI® fingerprint data collected by a wireless device; and configuring the trained machine learning model to estimate, according to the WI-FI® fingerprint data collected, the relevant position.
