The invention discloses a sound source sound intensity estimation method, apparatus and device, and a computer readable storage medium. The method comprises the steps of positioning an angle of a vehicle sound source relative to a microphone array based on a sound signal collected by the microphone array and video data collected by a camera device; calculating the distance between the vehicle sound source and the microphone array according to the angle of the vehicle sound source relative to the microphone array and the installation position information of the microphone array; and according to the distance and the intensity data of the sound signal of the vehicle sound source collected by the microphone array, sound intensity data of the vehicle sound source is calculated. According to the invention, the accuracy of the estimated noise intensity of the vehicle sound source is improved, and the monitoring and management precision of traffic noise is improved.
本发明公开了一种声源声音强度估计方法、装置、设备及计算机可读存储介质,所述方法包括:基于麦克风阵列采集的声音信号和摄像设备采集的视频数据定位车辆声源相对于麦克风阵列的角度;根据车辆声源相对于麦克风阵列的角度和麦克风阵列的安装位置信息,计算得到车辆声源与麦克风阵列之间的距离;根据距离和麦克风阵列采集到的车辆声源的声音信号的强度数据,计算得到车辆声源处的声音强度数据。本发明提高了所估计出的车辆声源的噪声强度的准确度,进而利于提高对交通噪声的监测和管理精准度。
