Abstract

The invention discloses a video camera parameter adjusting method, a directed video camera, and a directed video camera system. The video camera parameter adjusting method comprises steps that a target video object required to be shot is determined; a target video camera used for shooting the target video object is selected from the various video cameras of the directed video camera system according to a preset directed strategy; the first three-dimensional coordinate of the target video object is acquired, and the first three-dimensional coordinate is the three-dimensional coordinate of the target video object in a first coordinate system corresponding to the target video camera; the shooting parameter of the target video camera is adjusted to be the shooting camera corresponding to the first three-dimensional coordinate, and video images are output, after the shooting parameter is adjusted. By adopting the technical scheme provided by the invention, the efficiency of adjusting the parameter of the video camera is improved, and the shooting effect of the video camera is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for adjusting camera parameters, a broadcast guiding camera and a system. Background technique [0002] With the continuous development of image processing technology and the Internet, more and more scenarios need to use video conferencing, which brings great convenience to remote communication between users. At present, when conducting a video conference, it is often necessary to deploy multiple cameras for shooting, so as to obtain frontal images of participants. For example, see figure 1 , figure 1 It is a schematic diagram of a video conferencing scene. Such as figure 1 As shown, in this scene, the conference room adopts a long and elliptical conference table, and the seats of the participants surround the conference table. The participants include A and B, and the participants A and B sit opposite each other. Cameras C0 and C1 are arranged on both side...
