Virtual and real camera picture synchronization method and device and storage medium

Abstract

The invention provides a virtual and real camera picture synchronization method and device and a storage medium, and relates to the technical field of computers, and the method comprises the steps: enabling the motion data of an LED picture, a real camera and a synthesis end virtual camera to access time codes, comparing the three time codes which are received at the same time, and selecting the slowest time code as a reference. The motion data, the real camera picture data and the virtual camera picture data are synthesized in a frame synchronization mode, then values are taken from the cache pools to be synthesized, the slowest time code is selected as a reference to generate the lowest delay, namely, the interval time of performance and final picture seeing, and the time codes as indexes are in one-to-one correspondence with the corresponding data, so that the motion data, the real camera picture data and the virtual camera picture data are synthesized in a frame synchronization mode. Therefore, the problem of picture tearing during real-time synthesis of the virtual camera picture and the real camera picture in the virtual film production is solved, and the real-time performance, the integrity and the picture uniformity of the virtual film production are further improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method, device and storage medium for synchronizing virtual and real camera images. Background technique [0002] LED ring screen virtual production is a new film and television shooting technology that projects 3D virtual scenes onto the LED ring screen and shoots the LED ring screen with a real camera that matches the position of the virtual camera. Compared with the existing production system that uses a green screen environment, LED ring screen virtual production solves the problem of poor visualization of performance content, allowing directors and actors to see the content and pictures of the performance in real time, and also reduces the difficulty of post-production. With the workload, to achieve post-front. [0003] In order to form the final picture, it is necessary to synthesize the virtual camera picture and the real camera picture. In the existing scheme, the fi...

Problems solved by technology

[0003] In order to form the final picture, it is necessary to synthesize the virtual camera picture and the real camera picture. In the existing scheme, the final picture needs to be manually synthesized in the later stage, and there is no way to achieve real-time synthesis. The reason is largely because there is no way to achieve virtual reality. The synchronization of the camera causes the real-time synthesized picture to be torn, which affects the real-time performance, integrity and picture unity of the virtual production to a great extent.
