Design and implementation of smart vehicle auditory perception system

Abstract

With the rapid development of science and technology, smart cars are widely used in daily life, scientific research, measurement and prediction, industrial production and many other fields. This paper focuses on the in-depth study of sound source localization technology in smart car auditory perception. Based on the research on the existing microphone array, according to the application scenario of the smart car auditory perception system design, the four-element uniform circular array microphone structure is designed, and its receiving model is established. Based on the strong phasor method, and on the basis of the sound intensity vector method, a method of spatial directivity enhancement is proposed to improve the accuracy of sound source localization in the auditory perception system of service robots. This significantly improves the automatic accuracy of sound source localization of the vehicle auditory perception system.
