Document Type and Number:
WIPO Patent Application WO/2017/121168
Kind Code:
A1
Abstract:
Disclosed are a cluster-based magnetic positioning method, device, and system. The method comprises: acquiring a wireless signal and a magnetic field signal (S101); performing, according to the wireless signal, first positioning on a target (S102); and within a range of the first positioning, performing, according to the magnetic field signal, second positioning on the target (S103). In the present invention, first rough positioning of a target is performed via a wireless signal, and then within a range of the first positioning, precise positioning of the target is performed, thereby decreasing the amount of calculation, reducing the complexity of calculation, and enhancing the precision of positioning.
