Problems solved by technology

The disadvantage is that the field of view recorded in the screen is limited, and the viewer cannot choose to display the scene outside the field of view. The viewer can only passively accept what kind of screen is played, lacking a sense of change and immersive interaction, focusing and detailing but lacking breadth, making the The charm of 3D video is greatly reduced
However, because the panoramic field of view contained in VR video is too grand, the resolution of the image in the display window is relatively low. For example, the definition of 4K VR panoramic video in the display window is only equivalent to 480P; VR video generally adopts fixed focal length and focus Strictly speaking, it belongs to "myopia". Even if the video reaches a full-view retinal resolution of 20K, the viewer has a very high resolution of the scene near the VR camera. The ability to distinguish distant objects is also greatly reduced. By zooming in on the video and zooming in on the object of interest for close viewing, the angular resolution of the window image will be further reduced, and a good VR display effect cannot be obtained.
That is to say, although the VR video data is huge, the expressiveness of details is still insufficient after dispersion; due to the limitation of VR shooting equipment technology and volume, it is difficult to record the three-dimensional sense of the details of the scene a little farther away.
VR video can be summarized as having breadth but no details and no focus, giving viewers a general view and lacking the feeling of key description

Embodiment example 1

[0042] Implementation case 1, VR and 3D separate shooting. Suitable for most environments including theatre, stage, event, travel recording or live broadcast. The professional VR device (20) is separated from the 3D shooting device (21), and the 3D shooting device (21) can move and track the hotspot area (22), such as Figure 6 As shown, the multi-channel videos captured by the professional VR equipment (20) can be stitched to output 8K, 16K or even 24K (3D) VR videos, and the 3D shooting equipment (21) can output single-eye 4K, 8K ultra-high-definition videos. Align the edited VR video (9), 3D video (10), and audio (11) time stamps and link them into a VR3D video group (12). The so-called time stamp alignment refers to VR, 3D frame images and sounds recorded at the same time , at the same moment in the video and audio stream timestamp (6). The VR3D video group data stream is transmitted, distributed, and shared to user terminals such as VR headsets and 3D display screens th...

Embodiment example 2

[0043] Implementation Case 2: VR3D videos are shot with professional or ultra-high-definition all-in-one cameras. It can be applied to live broadcast or recording of tourism, stage, shopping guide, activity recording, etc., and can also realize two-way video interaction with VR3D video client. like Figure 7 As shown, the professional VR3D all-in-one machine has 24 VR lenses, which can shoot (3D) VR videos of no less than 24K (9); the medium-telephoto 3D lens group (24) can shoot ultra-high-definition 3D videos of 4K or 8K per eye ( 10). like Figure 8 As shown, the ultra-high-definition VR3D all-in-one machine has 6 VR lenses (25), which can shoot 8K and 16K (2D) VR videos (9); one side is marked with wide lens (29), VR lens (25), medium-length The focal lens (30) forms a zoom 3D lens group, which can shoot a single-eye 4K 3D video (10). On the VR video (9), use a mask to mark the hotspot area (22) that changes over time with a flashing virtual frame. When the user's eyes...

Embodiment example 3

[0044] Implementation Case 3: VR3D video is shot by a portable all-in-one machine or a plug-in VR3D mobile phone, which is convenient and free to move, and can be applied to video calls, travel, live broadcast, short videos, etc. like Figure 9 As shown, the all-in-one machine has two fisheye VR lenses (31), which can shoot 4K and 8K (2D) VR videos (9); one side is marked with a wide lens (29), a fisheye VR lens (31), a medium The telephoto lens (30) forms a zoom 3D lens group, which can shoot 4K 3D video (10) for one eye. like Figure 10 As shown, the VR camera (32) is externally hung on the multi-lens mobile phone (33) through the mobile phone clip, and can shoot (2D) VR video (9) of 4K and 8K; the standard wide lens (29) and super wide lens (36) of the mobile phone ), a medium-telephoto lens (30) to form a zoom 3D lens group (35), which can shoot a single-eye 4K 3D video (10). The frame images of the VR video (9) and the 3D video (10) are stitched together to form a 4K*4...

Abstract

According to the VR3D video structure and the shooting and displaying method thereof disclosed by the invention, VR panoramic display, 3D video zooming and translation and VR / 3D switching technologies are combined, the defects of insufficient 3D video immersion and low VR display angle resolution are overcome, and the VR3D video structure has the characteristics of panoramic view immersion and hot spot region detail description. The VR3D video can be shot by adopting professional or convenient photographic equipment, transmission, distribution, sharing, high-definition panoramic display at a user side and free switching of the 3D video are realized under the support of a 5G network, the advantages of immersive display, human-scene interaction and three-dimensional vividness are realized, and a user can experience free and smooth impression in a virtual environment. By adopting the VR3D video technology and the shooting equipment, a brand new experience tourism, social contact, live broadcast and shopping platform can be created, and the portable VR3D all-in-one machine can also provide end-to-end bidirectional live video call for the user, so that the user can really experience that the career is the hand.

Description

Technical field: [0001] The invention relates to a VR3D video structure, and a shooting and displaying method. Background technique: [0002] 3D videos shot in various resolutions such as FHD, 4K, 8K, etc., each frame of 3D images can reach 4M~64M pixels. The advantage of high-definition 3D video is that when shooting with long and short focal lengths or zoom lens groups, it can track far and near hot spots in the field of view, and the full screen meets the resolution requirements required by the retina screen. The disadvantage is that the field of view recorded in the screen is limited, and the viewer cannot choose to display the scene outside the field of view. The viewer can only passively accept what kind of screen is played, lacking a sense of change and immersive interaction, focusing and detailing but lacking breadth, making the The charm of 3D video is greatly reduced. [0003] VR adopts 360° panoramic 3D recording and active look-around technology, which brings a...
