Virtual-reality video/image format and shooting, processing and playing method and device

Abstract

The invention discloses a virtual-reality video / image format, and shooting, processing and playing method and device. Through the VR image and video with locked visual angle provided by the invention,only the scene less than and equal to the visual field of the ordinary people is collected and shot so as to be presented to the audience; when the VR image and video are played, the picture is fixedly displayed on a head-mounted display screen, thereby changing the traditional active virtual-reality immersive experience into the passive virtual-reality immersive experience. Since the head-mounted display is fixed on the head, the picture center is always over against the audience no matter the audience how to change the head direction; therefore, the image and video can effectively compressthe periphery part of the picture according to the physiological characteristics of the eyes of the human. Due to the mixed reality setting proposed by the invention, the function of displaying the image collected by a camera on the head-mounted display screen in real time is provided, and the digital text image information can be overlapped on the true reality picture, thereby realizing the function of enhancing the reality application.

Description

technical field [0001] The present invention relates to the technical field of virtual reality, in particular to a virtual reality video / image format and a shooting, processing and playing method and device. Background technique [0002] With the emergence of more and more VR devices including PC VR helmets, VR all-in-one machines, mobile phones and VR boxes, watching VR videos has become one of the main uses of these VR devices in the hands of users. At present, these VR videos are shot and spliced ​​using VR camera equipment equipped with multiple fisheye lenses. Because VR video needs to collect images for the left and right eyes separately, the collection range is very large, reaching 180 degrees up and down, 180 degrees left and right, or 360 degrees. Very high demands are placed on the performance of sensors and processors. Therefore, it is difficult for the current VR camera equipment to achieve the unity of high performance and portability.

Problems solved by technology

Moreover, high-resolution and high-frame-rate videos themselves have high requirements on device hardware. Some high-resolution VR videos cannot be played smoothly on low-end VR devices.

[0004] On the other hand, the creation of VR videos also faces a huge bottleneck, because viewers can freely move their sights in VR videos, and creators cannot control or predict the sights of viewers, so the scene scheduling is facing a major problem; It is also very limited; and the lens of VR shooting is often fixed or rarely moves. There are two reasons. One reason is that because of the nature of panoramic 360° or half-view 180° VR videos, the lens must be placed horizontally, and it cannot be shot upwards or When shooting from above, when shooting a panoramic 360° picture, the lens cannot even rotate the lens horizontally

Another reason is that the user's line of sight can move freely. If the viewer changes his line of sight while the shooting camera moves at the same time, the incongruity between the two will aggravate the audience's vertigo.
