Title:
SIGNAL ANTI-NOISE-BASED INDOOR POSITIONING METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/060430
Kind Code:
A1
Abstract:
A signal anti-noise-based indoor positioning method and system, the method comprising: receiving signal information and data packets broadcasted by signal base stations constructed indoors (S101), the data packets comprising distance values from the signal base stations to terminals to be positioned and position information of the signal base stations, and the signal information comprising RSSI values from the signal base stations to each terminal and the propagation time of electromagnetic signals or the propagation time of sound signals; according to the signal information, determining the noise distances from the base stations to each terminal (S102); and according to the distance values of the terminals under different signal base stations, the noise distances from different signal base stations to the terminals and the position information of the signal base stations constructed indoors, positioning the terminals by using an indoor positioning algorithm (S103). In the method, the anti-noise property and accuracy of indoor positioning may be improved.
