Embodiment 1

[0031] figure 1 It is a flow chart of a camera rotation control method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where a user makes a video call. The method can be executed by a camera rotation control device, which can be composed of hardware and / or software, and can generally be integrated in various terminal devices (such as mobile phones, tablet computers or video call robots) that can be used for video calls. The camera is used together to realize the rotation control of the camera, wherein the camera can be integrally formed with the terminal device, or can be used in combination with the terminal device as an external accessory.

[0032] The method of this embodiment specifically includes the following steps:

[0033] Step 110, during the video call, acquire the identity feature information of the calling user.

[0034] Among them, video call is a communication method for real-time transmission of human voice a...

Abstract

The invention discloses a method for controlling the rotation of a camera. The method comprises: during a video communication process, identity characteristic information of a communication user is obtained; according to the identity feature information, a rotating speed of a camera matching the communication user is determined; a set number of face images, captured by the camera within a set timeinterval, of the communication user are obtained; if the face rotation frequency, determined by adjacent face images among the set number of face images, of the communication user within the set timeinterval does not exceed a frequency threshold, a first face image and a last face image among the face images captured within the set time interval are obtained; according to the first face image and the last face image, a face rotation parameter is determined; and on the basis of the rotating speed and the face rotation parameter, the camera is controlled to make rotation. Therefore, the personalized need of the user during the video communication process can be met; the video experience of the user is improved; and a phenomenon that the user at the other side in video communication feels uncomfortable because of frequent rotation of the face of the user at one side is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of control, and in particular, to a camera rotation control method, device, device and storage medium. Background technique [0002] In recent years, with the rapid development of science and technology, video calls have become the main communication technology for communication between people, and the camera is one of the essential devices in the process of video calls. Controlling the rotation of the camera has become a video call Part of meeting the individual needs of users. [0003] In the prior art solutions, the motion control of the camera is generally to confirm the user information through the face recognition system, and when the user's face rotates, track the user's face rotation position at a certain speed. Among them, the tracking speed mainly uses a preset constant tracking speed. [0004] As users' requirements for video calls continue to increase, existing technic...
