Scene analysis acoustic imaging device based on spherical microphone array and analysis method

Abstract

The invention discloses scene analysis acoustic imaging equipment based on a spherical microphone array and an analysis method. The scene analysis acoustic imaging equipment comprises a computer, and one side of the computer is connected with a microphone array assembly through a data line; according to the device, the scene lens is arranged outside the device, scene elements can be effectively captured, the type of the scene is judged according to the scene elements, the method and the device can be combined with sound source analysis, the sound source can be judged, the sound source object can be judged, and due to the fact that scene analysis and sound source analysis are combined, the sound source object can be judged. According to the method, analysis results can be more accurate, functions are powerful, meanwhile, segmentation processing specially aiming at voice signals is arranged in the method, noise analysis and voice impurity removal are carried out on the voice signals, the clarity of the voice signals can be effectively guaranteed, the disorder of the voice signals is reduced, the accuracy of subsequent sound source analysis is improved, and the method is suitable for popularization and application. The use effect of the method is improved, and the method is suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of acoustics, and in particular relates to an acoustic imaging device and an analysis method. Background technique [0002] Acoustic analysis, as the name implies, is to perform acoustic analysis on the sound source. In order to better realize the acoustic analysis process, a microphone array has been developed. As the name implies, the microphone array is the arrangement of microphones. In fact, it is mainly composed of a certain number of acoustic sensors (usually microphones), which are used to sample and process the spatial characteristics of the sound field. [0003] The existing microphone array acoustic analysis equipment is generally only equipped with a sensor for capturing the sound source, which can only sample and process the spatial characteristics of the sound field, and does not have a scene lens on it, so it cannot analyze the scene in the space. Element capture and scene analysis cannot be ...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem of the existing microphone array acoustic analysis equipment, generally only sensors for capturing the sound source are provided, and only the spatial characteristics of the sound field can be sampled and processed, and no scene lens is arranged on it. , it is impossible to capture the elements of the scene in the space, and it is also impossible to perform scene analysis, and it is impossible to combine the two to achieve a comprehensive analysis process.
