Sound source localization method, device and storage medium

Abstract

The present application discloses a sound source localization method, device, and storage medium, which relate to the field of localization technology and are used to solve the problem in the prior art that the time delay difference between microphones needs to be calculated when locating the sound source, which leads to the present situation. Some sound source localization methods have a large amount of calculation and a long processing time. In this method, the audio signal to be positioned received by the pre-built circular microphone array and the delay difference coefficient set corresponding to each sound source position in the pre-stored delay difference coefficient table are input into the sound source orientation cost function, The output result is obtained; the corresponding sound source position when the output result is the maximum value is used as the sound source position of the audio signal to be located. In this way, the calculation time can be saved by looking up the delay difference coefficient table, and the processing speed can be increased; at the same time, the obtained audio signal can be made clearer through the ring microphone array, so that the obtained sound source position is more accurate.

Description

technical field [0001] The present application relates to the technical field of positioning, and in particular to a sound source localization method, device and storage medium. Background technique [0002] The positioning and tracking of sound is an important topic in the research of human-computer interaction, and it has a wide range of applications in the fields of monitoring and identification in security departments, video conference systems, multimedia systems, and robots. Usually, vision is the main way for people to obtain information, but in many cases, vision cannot provide complete information of the target, and it has certain limitations compared with hearing. Face tracking methods are vulnerable to factors such as video occlusion, illumination, and posture changes. Impact. In contrast to the limited visual range, the auditory system is omnidirectional and not limited by angle and position. People can hear sounds from any direction in three-dimensional space, ...
