Embodiment 1

[0043] Method embodiment 1 of the present invention can be through figure 1 Be explained:

[0044] 101. Obtain the panoramic view of the remote conference site, and the corresponding relationship between the panoramic view coordinate system of the remote conference site and the control coordinate system of the remote camera, wherein the panoramic view of the remote conference site is established by the remote camera, and the remote The corresponding relationship between the panoramic view coordinate system of the end venue and the control coordinate system of the far-end camera is established by the far end;

[0045] In implementation 101, the panoramic view of the remote conference site is established by the remote camera, and the corresponding relationship between the panoramic view coordinate system of the remote conference site and the control coordinate system of the remote camera is established by the remote end, and they are all established through It is obtained from ...

Embodiment 2

[0051] Method embodiment 2 of the present invention can pass figure 2 Be explained:

[0052] 201. Establish the control coordinate system of the remote camera, shoot the panoramic view of the remote conference site according to the control coordinate system of the remote camera, and establish the panoramic view coordinate system of the remote conference site and the control coordinates of the remote camera The corresponding relationship of the department;

[0053] When implementing 201, the process of establishing the control coordinate system of the far-end camera is specifically: setting the vertex of the upper left corner in the field of view of the far-end camera as the origin of the control coordinate system; The control coordinate system of the remote camera is established downward and inward along the paper.

[0054] The process of shooting the panoramic view of the far-end conference site according to the control coordinate system of the far-end camera is specifically...

Embodiment 3

[0063] Method embodiment 3 of the present invention can be through image 3 Be explained:

[0064] 301. Establish a control coordinate system of the remote camera;

[0065] In implementation 301, the control coordinate system of the far-end camera includes three-dimensional components, namely (P, T, Z), and its specific structure is shown in Figure 4 As shown, the control coordinate system of the remote camera includes three coordinate axes, p, t, and z axes, where the origin is o, the origin of the p direction is selected at the far left, and the right is the direction of increase; the origin of the t direction Select at the top, and the downward direction is the direction of increase; the origin of the z direction is selected at the minimum zoom point of the camera (that is, the place where the field of view is the largest), and the direction of its enlargement is the direction of increase. The control coordinates of the remote camera can be realized in steps, for example...

Abstract

The embodiment of the invention provides a control method of a remote camera used in a video conference, a system and a device thereof. The realization process is as follows: a panoramic view of a remote conference venue and the corresponding relation between the coordinate system of the panoramic view of the remote conference venue and the control coordinate system of the remote camera are obtained, wherein, the panoramic view of the remote conference venue is established by the remote camera, and the corresponding relation between the coordinate system of the panoramic view of the remote conference venue and the control coordinate system of the remote camera is established by the remote camera; and the remote camera is controlled according to the panoramic view of the remote conference venue and the corresponding relation between the two coordinate systems. The technical proposal of the invention helps a user at the terminal better control the remote camera to view different sites of the remote conference venue according to the corresponding relation, and the operation process is visualized and simple, thus improving the user experience.

Description

technical field [0001] The invention relates to the technical field of video conferencing, and in particular designs a control method, system and device for a remote camera. Background technique [0002] In the video conferencing system, the terminal camera generally adopts a camera with PTZ (Pan / Tilt / Zoom, panorama / oblique shot / zoom) control function. View different positions of the remote conference site to achieve better conference communication. [0003] In the prior art, there are two ways to adjust the remote camera. One way is: when the user controls the camera of the remote conference terminal (referred to as: the local end) through the local conference terminal (referred to as: the local end), the user directly controls the The far-end camera performs left, right, up-down, and zoom actions to control the far-end camera, and transmits the corresponding control command to the far-end through the signaling channel, and the remote-end controls its own camera to perform...
