Problems solved by technology

Domestic large-screen fusion technology has been developed for ten years, but the fusion area has always been blurred, dark and gray light cannot be integrated when the scene is dark, and there are bright bands in the fusion area when the difference between light and dark in the same frame is large.

Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0027] Such as figure 1 As shown, a real-time ultra-high-definition panoramic video generation and multi-channel synchronous playback system, the whole system consists of two parts: a real-time ultra-high-definition panoramic video generation system and an application playback system. The generation system is responsible for image collection and splicing; the application playback system is responsible for Apply panoramic video to dome screen or ring screen theater and play it;

[0028] Such as figure 2 As shown, the generation system is composed of two parts: the image acquisition part and the intelligent splicing part. The image acquisition part includes the HCI interactive module, the embedded camera array electronic control system and the m...

Abstract

The invention provides an ultra-high-definition panoramic video real-time generation and multi-channel synchronous play system, and relates to the technical field of panoramic camera shooting. According to the system, on the basis of camera array imaging and collecting and by means of GPU high-speed parallel processing characteristics, the high-definition image real-time splicing, correcting, dimming, code compressing and transmission functions are achieved, a multi-channel panoramic multi-camera and an application system of the multi-channel panoramic multi-camera are designed, appropriate reprojection models are selected in a self-adaption mode for different shooting modes such as the cylindrical surface shooting mode and the spherical surface shooting mode, the problems that existing panoramic camera shooting devices in China are generally not high in stability, low in resolution, poor in expansibility, short of instantaneity and the like are successfully solved, the highest product resolution can reach 4320 p to 12960 p, and the frame rate is 30 fps.

Description

technical field [0001] The invention relates to the technical field of panoramic photography, in particular to a system for real-time generation of ultra-high-definition panoramic video and multi-channel synchronous playback. Background technique [0002] In the field of panoramic photography, Sony, CarlZeiss, etc. have invented single-lens optical refraction panoramic imaging technology, but the resolution is limited, and can only generate ring images; You cannot shoot a video, and it takes a long time to take a single picture. At present, the panoramic stitching equipment produced in China has the problem of blurred and unclear stitching areas. When processing stitching, it is usually done manually by using AfterEffects, PS and other post-production software, which takes a lot of time. When restoring ultra-high-definition video, 4 to 16 projectors are required to splicing and merging into ring screens, dome screens, BOX screens, etc., and the number of projectors is large...
