Embodiment Construction

[0031] In the Bluetooth wireless technology for realizing position positioning, the Angle of Departure (AoD) positioning technology has attracted more and more attention. This technology can be applied in indoor environments to perform high-precision indoor positioning with a positioning accuracy of less than 1 m.

[0032] Reference figure 1 , figure 1 It is a schematic diagram of an application scenario of an AoD positioning method in the prior art. The transmitting end 11 transmits to the receiving antenna 13 via the antenna array 12, and then is received and analyzed by the receiving end 14. Specifically, based on the signals sent from different transmitters to the same receiver with different AoDs, or signals from different antennas in the antenna array of the same transmitter to the same receiver have different AoDs, according to the triangulation method, it is possible to calculate the difference between the receiver and one receiver. Or the relative coordinates of multiple...

Abstract

The invention discloses an angle of departure (AoD) positioning method and device, a computer readable memory medium and a terminal. The method comprises the following steps of: receiving AoD signalsof a plurality of transmitters; judging whether the transmitter is a valid transmitter or not according to propagation link quality of the AoD signal of each transmitter; and carrying out AoD positioning according to the AoD signal of the valid transmitter. According to the scheme provided by the invention, the transmitters with serious interference can be filtered and the AoD positioning is onlycarried out based on the valid transmitters, so the positioning accuracy is improved, and computing quantity of a receiver in an AoD positioning process is reduced.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to an AoD positioning method and device, a computer-readable storage medium, and a terminal. Background technique [0002] In the Bluetooth wireless technology for realizing positioning, the Angle of Departure (AoD) positioning technology has attracted more and more attention. This technology can be applied to high-precision indoor positioning in an indoor environment, with positioning accuracy within 1m. [0003] Specifically, the AoD positioning method is to receive signals sent from the transmitter (Transmitter) to the receiver (Receiver) of multiple antenna arrays, calculate the transmission angle of each transmitter based on the difference between the transmitter and the receiver, and then calculate the transmission angle of each transmitter based on the triangle In the measurement method, the relative coordinates of the receiving end and one or more sending ends are c...
