Problems solved by technology

Therefore, the current VR live broadcast is limited to non-stereoscopic two-dimensional panoramic content lacking three-dimensional information
However, most of the non-live 3D / VR videos currently on the market require strict on-site calibration in advance. In addition, the formed videos will break for near, transparent, and highly reflective objects in the scene, which greatly affects the experience.
[0003] Because the front-end detection equipment cannot directly and quickly collect enough 3D stereoscopic information, or the collected 3D stereoscopic information is too redundant, and the lack or redundancy of these 3D stereoscopic information needs to be continuously calculated, processed and improved in the later stage, resulting in image The output time delay is very long

Description

technical field [0001] The present invention relates to the technical field of VR acquisition control, in particular to a VR live broadcast-oriented three-dimensional panorama video acquisition system and acquisition method. Background technique [0002] With the development of artificial intelligence and 5G technology, VR technology has achieved great development and been widely used in recent years. However, there is still a big gap between VR technology and live 5G true 3D panoramic VR live broadcasting. At present, multi-camera systems are widely used in VR technology at home and abroad. Using this system solution to make VR videos, calculate optical flow for seamless splicing and stereoscopic rendering. Due to the huge amount of calculations for optical flow calculations and depth estimation, it is currently impossible to do so. From real-time synthesis and live broadcast, most video content is produced by post-event synthesis. For example, Google's Jump VR camera req...
