Problems solved by technology

[0002] Sound source localization and navigation devices are currently widely used in various fields. In the prior art, the way to improve the accuracy of sound source localization is mainly to increase the number of microphones. It is difficult to realize, and it will also enhance the noise signal interference of the microphone. Therefore, how to set up a better microphone array and use a better algorithm to achieve the best recognition effect with fewer microphones is an important issue in the existing field. issues that need resolving
[0003] In the prior art, there is a lack of a precise sound source localization navigation device; the sound source localization can be achieved by using a smaller number of microphones to achieve more accurate sound source localization, and errors are not easy to occur; Sound source localization navigation device that identifies and navigates to the location of the sound source

Abstract

The invention discloses a sound source positioning and navigation device comprising a power supply module which is used for supplying power to the device. The power supply module is connected with a master control module used for performing sound source position calculation. The master control module is connected with an information receiving module used for information receiving. Different coordinate systems are selected, and the sound source coordinates can be more accurately calculated by using the time delay between all the microphones under the condition that the number of the microphones is certain so that the wiring cost can be reduced and the accuracy of the device can be increased; besides, a semantic recognition device and a navigation device are arranged so that semantic recognition, sound source positioning and navigation can be reliably realized, and the device is enabled to be flexibly adaptive to various scenes.
