Zusammenfassung: | The invention discloses a single AP equipment positioning method and device based on beam forming and a storage medium, and relates to the technical field of indoor positioning, and the positioning method comprises the following steps: in an offline stage, setting the position of AP equipment and a to-be-positioned point, and appointing a beam direction by adjusting the phase difference between antennas to obtain a directional beam signal; the to-be-positioned point receives a beam signal sent by AP equipment; extracting an RSS signal value and a CSI signal value in the beam signal; the extracted RSS signal value and the extracted CSI signal value are subjected to filtering and phase correction processing in sequence, RSSI fingerprints are obtained, and a plurality of RSSI fingerprints form an RSSI fingerprint database; in the on-line stage, the AP device sends a beam, the beam direction is adjusted by using the phase difference of the antenna, and a directional beam signal is obtained; sending the beam signa |
