Embodiment 1

[0097] figure 2 For the location coordinate diagram of array microphone and sound source in preferred embodiment 1 of a control method provided by the embodiment of the present invention, refer to figure 2 , The array microphone has various physical forms, and this preferred embodiment is a linear array microphone, which includes at least 3 microphones. At the same time, the camera is placed together with the array microphone. The steps of this preferred embodiment are as follows:

[0098] In step 201, multiple microphones of array microphones are used to receive audio data respectively, filter out background noise and send to a processing center, or send to a processing center to filter out noise.

[0099] Step 202. The processing center extracts and separates the human voice part in the multi-channel audio data according to the frequency, and then calculates the time difference of the human voice received by multiple microphones according to the phase difference of the h...

Embodiment 2

[0137] image 3 The second preferred embodiment of a control method provided by the embodiment of the present invention is a schematic diagram of the position where the array microphone is placed directly in front of the camera, refer to image 3 , The array microphone has various physical forms, and this preferred embodiment is a circular array microphone, which includes at least 3 microphones. At the same time, the camera is not placed together with the array microphone, and the array microphone is placed directly in front of the camera. The steps of this preferred embodiment are as follows:

[0138] Step 301 , use the multiple microphones of the array microphone to receive audio data respectively, filter out the background noise and send to the processing center, or send to the processing center to filter out the noise.

[0139] In step 302, the processing center extracts and separates the human voice part in the multi-channel audio data according to the frequency, and th...

Embodiment 3

[0165] Figure 6 The schematic diagram of the third preferred embodiment of a control method provided by the embodiment of the present invention, refer to Figure 6 , The array microphone has various physical forms, and this preferred embodiment is a circular array microphone, which includes at least 3 microphones. The camera is not placed together with the array microphone, and the array microphone is placed in front of the camera and has a horizontal displacement. The coordinates of the sound source position are (x, y), and the coordinates of the camera relative to the array microphone are (l, -d). The steps of this preferred embodiment are as follows:

[0166] In step 401, x and y are obtained in a manner similar to steps 301-303 in the second preferred embodiment.

[0167] Step 402, align the camera angle with the direction indicated by the angle b, b=arctan((y+d) / (x-l)).

[0168] Among them, in the actual use scene, since the digital microphone and the camera at the v...

Abstract

Embodiments of the present invention provide a control method, a control device, and a control device. The control method includes: acquiring audio data containing sound information of a target sound source; determining position range information of the target sound source according to the audio data; controlling that the target sound source cannot be photographed currently according to the position range information The rotation of the photographing device enables the photographing device to photograph the target sound source. The embodiments of the present invention support the shooting device to be able to capture a target sound source outside the scope of the original screen.

Description

technical field [0001] Embodiments of the present invention relate to the field of image tracking, and in particular, to a control method, a control device, and a control device. Background technique [0002] During video communication, the camera needs to be pointed at the speaker. The existing solution is to use image recognition technology to recognize the face, and then remotely control the camera to point at the position of the face, but this solution cannot track a speaker who is beyond the range of the screen or another speaker who is outside the range of the screen. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present invention is to provide a control method, a control device and a control device, so as to support the shooting device to capture a target sound source outside the range of the original screen. [0004] In order to solve the above technical problems, the embodiments of the present invention provide the foll...
