Our proposed method estimates the direction of the microphone based on the knowledge that the spectral amplitude of a speaker in each direction is different. Additionally, the distance between the speaker and microphone is estimated based on the received amplitude value. The 2D location of the microphone is calculated from the estimated direction and distance values. We conducted real-environment experiments for two different types of box speakers at 14 points in 1.2m × 0.5m and confirmed that the 90-percentile localization error was 0.265m. We also discussed the systematic errors in the estimated distance values that occurred in the experiment and revealed that these errors were caused by the characteristics of the speakers.}, pages = {1298--1308}, title = {単一のスピーカを用いたモノラルマイクロフォンの屋内測位手法}, volume = {63}, year = {2022} }
