Problems solved by technology

Although the frame capture of a single object and the calculation of the camera pose are strengthened, the PTZ camera is not used, and it is not suitable for scene capture that specifies a specific target point.

Embodiment Construction

[0055] Below in conjunction with accompanying drawing, the present invention is described in further detail, before introducing the specific implementation method of the present invention, at first some basic concepts are explained:

[0056] (1) Fusion of virtual and real: Fusion display of virtual 3D models and real pictures or videos;

[0057] (2) Enhanced virtuality: collect scene information in the real scene, reproduce and display it to the user;

[0058] (3) PTZ camera: PTZ is the abbreviation of Pan (left and right rotation) / Tilt (pitch rotation) / Zoom (zoom) in security monitoring, which means that the camera pan / tilt can rotate up and down, left and right, and realize lens zoom and zoom control;

[0059] (4) Roaming perspective: the user's observation perspective in the virtual-real fusion scene;

[0060] (5) Hedging: The angle of view is opposite. The user's angle of view and the camera's angle of view will be opposed to each other, which will cause the camera's shoo...

Abstract

The present invention proposes a joint control system and method for multiple PTZ cameras in a virtual-real fusion scene, including camera screening, local picture planning and camera attitude calculation. The present invention can provide the joint control function of multiple PTZ cameras for the virtual-real fusion video scene, improve the utilization rate of multiple cameras, expand the picture capture range of the scene, optimize the camera monitoring area, thereby improving the viewing experience of users.

Description

technical field [0001] The present invention relates to the technical field of enhanced virtual environment, and more specifically, relates to a joint control system and method of multiple PTZ cameras in a virtual-real fusion scene. Background technique [0002] Augmented Virtual Environment (AVE) is a technology used to display multiple pictures or video streams from any angle in a 3D virtual environment. There are important applications in the field of integrated monitoring systems. PTZ cameras have the advantages of high flexibility and wide monitoring range. The addition of PTZ cameras in the enhanced virtual environment greatly enhances the amount of information captured in virtual-real fusion scenes and improves the utilization of camera resources. However, when there are multiple PTZ cameras in the scene, calling a single PTZ camera cannot make full use of camera resources, and the obtained field of view is also limited. Considering the above problems, choosing to u...
