Embodiment Construction

[0018] The preferred embodiments of the present invention are given below to describe the technical solution of the present invention in detail.

[0019] The intelligent robot rotation method based on sound source localization and human face detection of the present invention comprises the following steps:

[0020] Step 1: Receive the wake-up words and activate them; convert the wake-up words into syllables, and then decompose them into phoneme sequences, for example, turn off the light->guan bi dian deng->gu uan b i d ian deng, each phoneme corresponds to an acoustic A model that matches the collected audio signal with the phoneme model of the wake word.

[0021] Step 2, using the multi-microphone sound source localization technology to determine the general direction of the target person, and controlling the robot head to rotate to the target direction; the multi-microphone sound source localization technology adopted in the present invention is a voice localization technolo...

Abstract

The invention discloses an intelligent robot rotation method based on sound source positioning and face detection. The method comprises the steps of (1) receiving a wake-up word and starting, (2) determining the general direction of a target person by using a multi-microphone sound source positioning technology, and controlling the head of a robot to a target direction, (3) turning a head camera to the direction of the target person to apply face positioning technology, and collecting an image through the head camera, (4) after collecting the image through the head camera, carrying out more precise positioning based on the face detection technology, and finally turning the head of the robot to point at the direction of a target speaker. According to the method, the positioning accuracy can be improved, and the personified effect of the interaction between a user and the robot is improved greatly.

Description

technical field [0001] The invention relates to an intelligent robot rotation method, in particular to an intelligent robot rotation method based on sound source localization and human face detection. Background technique [0002] In conventional anthropomorphic smart home robot products, most of the head rotations are in a preset or random way, and it is difficult not to achieve an anthropomorphic effect. A small number of multi-mic sound source localization is used, but limited by hardware size, environmental noise and algorithm performance, its positioning accuracy is not very high, and it can only detect the approximate direction and position of the sound source. [0003] Face detection technology has been widely used, including cameras, camera monitoring, etc. Its advantage is high detection accuracy, but the defect is that the coverage of the lens is limited. If the image collected by the lens does not face the target face, it cannot be detected. out. The sound sourc...
