Abstract

The invention discloses a camera control method, a device and a camera. The camera control method comprises the following steps of: firstly, determining pixel point coordinates of a target object in a scene image and pixel point coordinates of the target object in a depth image in each detection period; secondly, obtaining a distance between the target object and the camera based on the pixel point coordinates of the target object in the depth image; and lastly, adjusting a focal distance of the camera by utilizing a first distance obtained in a first detection period and a second distance obtained in a second detection period. The camera control method is applied to the camera, and an image sensor used for generating the scene image and a depth sensor used for generating a depth image of the corresponding scene are arranged in the camera. Through the method, the distance between the target object and the camera in each detection period can be obtained, the focal distance of the camera is adjusted through the distance, an algorithm is simple and the accuracy of zooming is improved.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a camera control method, device and camera. Background technique [0002] The camera used for video conferencing is the basic equipment of the video conferencing system. The video conferencing system is usually used in more than two locations. video and transmit it to other cameras, enabling users in different locations to communicate with each other via video. [0003] During a video conference, it is often necessary to adjust the focal length of the camera to achieve zooming of the camera. For example, the speaker is far away from the camera, resulting in a small image of the speaker in the video captured by the camera, making it impossible for users in other locations to see the expression of the speaker clearly through the video, and the communication experience is poor. In this case , it is necessary to adjust the focal length of the camera so that t...
