Abstract

The invention relates to a sound source identification and positioning device and especially relates to a portable double-microphone sound source identification and positioning device. The technical problem to be solved is to provide the portable double-microphone sound source identification and positioning device which is simple in structure, small in size, convenient to carry and more visual in display result. The portable double-microphone sound source identification and positioning device comprises a microphone A, a microphone B, a pre-amplifier A, a pre-amplifier B, a support, a signal acquisition module, a sound source identification and positioning module, a storage module and a displayer. The portable double-microphone sound source identification and positioning device solves the defects that an existing sound source identification and positioning device is large in size, and inconvenient to transport and carry; the device is simple in structure, small in size, convenient to carry, capable of identifying sound sources from different directions, small in computation complexity, high in real-time performance, and suitable for being applied to an embedded system; and the device is equipped with a liquid crystal display screen, so that the display results are more visual.

Description

technical field [0001] The invention relates to a sound source identification and positioning device, in particular to a portable double-microphone sound source identification and positioning device. Background technique [0002] In the field of intelligent monitoring and mobile robot research, the separation and location of sound source signals has always been a research hotspot. How to make a robot use only two microphones to complete the identification and location of sound sources like a human is a difficult research point; In a noisy environment, sound source identification and location technology can focus on the target signal of interest to the user, suppress interference noise, and help to separate aliased speech; , search and rescue, military and national defense and many other fields have important application value. [0003] The existing sound source directional device adopts a large number of microphone array elements and a large volume. There are only large-sca...
