Embodiment Construction

[0028] The technical content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Such as figure 1 As shown, in one embodiment of the virtual studio system provided by the present invention, two or more LED screens are selected to construct an observation window of a virtual three-dimensional space in a two-by-two orthogonal manner, and then the real-time rendering technology will The virtual three-dimensional space is mapped onto the LED screen with the correct perspective relationship, so as to build a real shooting scene. Finally, under the capture of the camera tracking system and the processing of hardware, the virtual studio system can output high-definition and realistic 3D images in real time.

[0030] It should be noted that the construction of a three-dimensional space is not limited to the use of two-by-two orthogonal LED screens. Other methods include setting up two intersecting...

Abstract

The invention discloses an LED screen real-time correction method oriented to a virtual studio environment and a virtual studio system. The LED screen real-time correction method comprises the steps of tracking the position of a camera in a three-dimensional space built by an LED screen in real time, and obtaining the spatial position relation of each area in the LED screen relative to the camera; and according to the influence of the spatial position relation on the LED display effect, dynamically correcting display elements of different areas of the LED screen. According to the invention, the shooting effect of the XR virtual studio technology can be improved.

Description

technical field [0001] The invention relates to a method for real-time correction of LED screens, in particular to a method for real-time correction of different areas of the LED screen facing the needs of a virtual studio environment, and also relates to a virtual studio system using the method, which belongs to XR virtual studio technology field. Background technique [0002] XR (eXtended Reality, extended reality) virtual studio technology is a virtual production method that uses the deep integration of LED screens, camera tracking systems and real-time graphics rendering engines to place performers in the virtual world in real time without green screens and post-production processes . In terms of practical application, XR virtual studio technology has a tendency to subvert and replace the original blue-green box shooting method. [0003] In XR virtual studio technology, a high-quality LED screen (usually presented as a ring screen or dome screen) will simultaneously di...
