Method for determining beam forming angle of microphone, and related device

Abstract

The embodiment of the invention relates to the technical field of image processing, and discloses a method for determining a beam forming angle of a microphone, and a related device. The method comprises the steps: detecting a sound signal in an environment; determining the beam forming angle of the microphone according to the source direction of the sound signal if the sound signal is detected and there is definitely wake-up prompt information in the sound signal, or else judging whether there is an interaction object or not: determining the position of the interaction object if there is theinteraction object, and determining the beam forming angle of the microphone according to the position of the interaction object. A robot can determine the beam forming angle of the microphone throughcombining the judgment of whether there are the sound signal and the interaction object, thereby achieving the free interaction between the robot and the interaction object, and solving a problem that a robot just can achieve the passive communication in the prior art because the robot just can wake up only when a keyword is detected, and problems of frequent and lagged interaction.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of artificial intelligence, and in particular to a method and a related device for determining a beamforming angle of a microphone. Background technique [0002] With the rapid development of artificial intelligence, the application of intelligent robots is becoming more and more extensive. The robot perceives the surrounding environment through a variety of sensors, such as the sound in the environment through the sound sensor, and the people or objects in the environment through the image sensor. [0003] At present, how the intelligent robot locates the position of the interactive object is a common concern in the industry. Microphone array-based sound source localization and beamforming (Beamforming) are currently the main sound source localization methods. The main positioning process of this positioning method is: the robot detects the sound signal, wakes up after detecting that...

AI Technical Summary

Problems solved by technology

[0004] The inventor found that at least the following problems exist in the prior art: in the method of locating after wake-up based on keywords, the robot will only be woken up after detecting the keywords (such as the name of the robot) in the sound signal, which is a passive wake-up and the interaction is cumbersome , with hysteresis
