Embodiment Construction
[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0022] Such as figure 1 As shown, a camera angle calibration method of a robot voice positioning process disclosed by the present invention comprises the following steps:
[0023] The first step is rough voice positioning: after the robot collects the sound waves, it locates the voice source position through the voice positioning module, and turns the face of the robot with the camera to the approximate voice source position according to the voice source position information;
[0024] The second step, face detection: use the camera on the face of the r...
