Problems solved by technology

[0011] With the existing foreground implant technology, the host cannot directly see the implanted items in the shooting environment, including the real-time position and shape of the items, and must use the back screen to see the positional relationship between himself and the implanted items, and then adjust himself The position of the station is to prevent crossing the country, and there is a delay in the signal, which will cause restraint in the performance and poor live broadcast effect

specific Embodiment

[0056] This solution uses Leyard's LED display screen, the main screen size is 3*4 meters, and the ground screen size is 4*4 meters; the virtual rendering server uses Lenovo HP (HP) graphics workstation, and the foreground implantation server uses 7D The prospect is implanted in a dedicated server, and the operating system installed is Windows operating system or UNIX, Linux open source operating system, or other suitable operating systems. The video camera used is Sony's high-definition video camera. The virtual rendering server connects the virtual scene signal to the LED display screen through the HDMI cable. The virtual rendering server and the foreground implant server are connected through a network cable to realize synchronous work. The camera is fixed at a position 4 meters away from the screen, facing the display screen, and the camera signal Connect to the video capture card of the foreground implant server through the SDI signal cable, and the final effect of superi...

Abstract

The invention discloses a method and system for implanting the position of AR foreground items in a virtual display space. The method includes the following steps: displaying three-dimensional virtual display pictures on multiple LED display screens to form a three-dimensional virtual display space; Implanting the AR foreground item into the collected image of the three-dimensional virtual display space image to form an overall three-dimensional display image; displaying a shadow position corresponding to the AR foreground item in the three-dimensional virtual display space in real time. Through the technical solution of the present invention, it can help the presenter to visually and smoothly complete the program production without using the look-back screen (synthetic screen), so that the cooperation between the presenter and the content is simple and clear, and the program broadcasting effect is more natural.

Description

technical field [0001] The present invention relates to the technical field of data display, in particular to a method and system for implanting the position of AR foreground items in a virtual display space. Background technique [0002] With the continuous introduction of the concept of integrated media and the continuous improvement of the audience's ability to appreciate programs, the video signal has been upgraded from the traditional PAL system to 1080i / 1080P. The emergence of various media platforms has made audiences have higher and higher requirements for the media industry. In addition to adhering to "content is king", media professionals also have new pursuits in terms of program formats and technological innovation. [0003] Augmented reality technology AR renders and synthesizes the camera signal and the three-dimensional virtual scene synchronously, and superimposes the real environment and the virtual object in the same picture or space, so that the real scen...
