Positioning method and device based on sound

The invention discloses a sound-based positioning method and device. The method comprises the following steps: step 1, acquiring sound velocity data; step 2, acquiring receiving position data and receiving signal data; step 3, obtaining receiving time delay data according to the receiving signal data; 4, correcting the received time delay data by adopting the correction model to obtain corrected time delay data; and 5, carrying out positioning calculation by adopting the sound velocity data, the receiving position data and the corrected time delay data to obtain predicted sound source position data. According to the method and the device, the received time delay data is corrected by adopting the correction model, so that the time delay data error caused by the self-precision influence of instrument hardware and the concurrency and non-concurrency influence of program software is reduced. 本发明公开了一种基于声音的定位方法及装置，包括以下步骤：步骤一，获取声速数据；步骤二，获取接收位置数据和接收信号数据；步骤三，根据接收信号数据得到接收时延数据；步骤四，采用修正模型对接收时延数据进行修正，得到修正时延数据；步骤五，采用声速数据、接
