Abstract
At present, the acoustic localization method is widely used. The high-precision acoustic localization algorithm is required urgently. The temperature is one major external factor which affects the localization precision greatly in the acoustic localization algorithm based on TDOA. It is found that the regional mean errors of the acoustic localization are smaller than others when the temperature changes around 25°C. And the regional mean errors of the acoustic localization change monotonically with temperature. One acoustic localization algorithm based on ten-element stereo array is presented. This algorithm has been optimized by temperature amendment. The experimental results show that the optimized algorithm has better localization precision than the original algorithm. The mean errors of X, Y, Z-coordinate using the optimized algorithm are separately 0.0758 m, 0.0586 m 0.0348 m smaller than the original algorithm.
