Embodiment Construction
[0024] Since the transmission speed of sound is much lower than that of electromagnetic wave signals, it is easy to achieve synchronization, and has the advantages of low energy consumption and low cost; the acoustic characteristics are not easily disturbed, and the working distance can reach tens of meters, which can effectively meet the signal coverage of indoor scenes. In addition, a directional signal beam can be formed based on a single sound source transmitter. Taking advantage of this advantage, the present invention provides an audio positioning method based on angle estimation, which can realize low-cost, high-precision, and wide-coverage indoor positioning.
[0025] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0026] This embodiment provides an audio positioning method based on emission a...
