VR3D video

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...

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
