Problems solved by technology
However, when using both hands to directly control the camera, the operator cannot stay away from the operation terminal, and it is even difficult for disabled people with inconvenient hands to directly control the camera; when using the human eye gaze tracking technology to control the camera, it is severely limited by the operator and the operation terminal. The distance between them is easily affected by factors such as operator's position, eyeball rotation range, through-hole zoom state, etc.

The embodiment of the invention provides a method and device for controlling multiple cameras. The method comprises the steps of obtaining a current control mode of an operation terminal of a camera control system; collecting facial action characteristics of the user, wherein the facial action characteristics comprise one or more of blinking times of the user, closing duration of eyes, nodding times of the user, a rotating direction of the face, a rotating angle of the face and opening and closing times of the mouth; and based on an instruction mapping relationship, sending an instruction for controlling a camera control system and switching and controlling a plurality of cameras according to the current control mode and the facial action characteristics. Compared with a camera control method of a human eye sight line tracking technology, the method is convenient for handicapped people with two inconvenient hands, login and logout of the user and switching control of multiple cameras are realized, and the influence of factors such as the standing position of an operator, the eyeball rotation amplitude and the pupil zooming state is effectively avoided.
Description
technical field [0001] Embodiments of the present application relate to the technical field of image management, and in particular, to a method and device for controlling multiple cameras. Background technique [0002] At present, there are mainly two ways to control the camera: using both hands to directly control the camera; and using the human eye gaze tracking technology to control the camera. However, when using both hands to directly control the camera, the operator cannot stay away from the operation terminal, and it is even difficult for disabled people with inconvenient hands to directly control the camera; when using the human eye gaze tracking technology to control the camera, it is severely limited by the operator and the operation terminal. The distance between them is easily affected by factors such as the operator's position, eyeball rotation range, and through-hole zoom status. Contents of the invention [0003] In order to facilitate the manipulation of c...
