Description
Technical field
The present invention relates to VR video capture technical fields, more particularly to a kind of 3D image pickup method of VR video.
Background technique
Virtual reality（Virtual Reality_VR）It is an important research direction of present Environment Science, it is therein
VR video is even more the hot spot studied.And there was only panoramic video in current video（Or panoramic picture）Could be used as VR video into
Row viewing.But the comparison of panoramic video content is difficult, so content is few.
The shooting of VR video and playback method are in the prior art：Firstly, pre- photographed scene front, back, left, right, up,
Lower six direction carries out the shooting of video；Then, the Video Composition spherical shape of the six direction of shooting is regarded using dedicated software
Frequently, or generate expand horizontally flat image；Finally, playing video by VR special player for user's viewing.
VR video is although large number of, but cannot all accomplish there is 360 degree of real 3D senses, and would generally use use
The householder methods such as ' camera lens ', ' plot ' allow user to ignore the problematic place of tool.
Therefore how to shoot the VR video with 360 degree of real 3D senses using simple mode is not yet can at present
The technical problem of solution and highly desirable can occur the technology of user.
Summary of the invention
In order to solve the shortcomings of the prior art, the purpose of the present invention is to provide a kind of shooting sides 3D of VR video
Method, it may be possible to which obtaining, there is the VR video of 360 degree of real 3D senses to meet to overcome technical problem in the prior art

To achieve the above object, camera pedestal equipment, method provided by the invention, includes the following steps：
In the horizontal direction of the front, rear, left and right of pre- photographed scene 4, two groups of video cameras are arranged respectively in accordance with human eye interpupillary distance；
On upper and lower 2 vertical directions of pre- photographed scene, it is respectively arranged one group of video camera；
Acquire the preceding visual angle images of left and right eyes of pre- photographed scene with the video camera of erection, back angle images of left and right eyes, LOOK LEFT images of left and right eyes,
The video or image of LOOK RIGHT images of left and right eyes, upward angle of visibility and downwards angle of visibility；
According to visual angle, left eye, right eye, by the video or image of acquisition, be processed into the images of left and right eyes of VR standard spherical video or
Person's image；
By the spherical video of images of left and right eyes or Image Mosaic in a video or image, the VR view of pre- photographed scene is obtained
Frequency or image.
Further, described in the horizontal direction of the front, rear, left and right of pre- photographed scene 4, respectively in accordance with human eye interpupillary distance
The step of arranging two groups of video cameras be：With horizontal plane to be axial, in the horizontal direction of the front, rear, left and right of pre- photographed scene 4,
Respectively in accordance with the horizontally disposed two groups of video cameras of human eye interpupillary distance.
Further, described on upper and lower 2 vertical directions of pre- photographed scene, it is respectively arranged the step of one group of video camera
Suddenly it is：It is axially, on upper and lower 2 vertical directions of pre- photographed scene, to be respectively perpendicular one group of arrangement and take the photograph with the normal of horizontal plane
Camera.
Further, pre- photographed scene is located at the center for the video camera arranged in the horizontal direction of its front, rear, left and right 4
Position.
Further, pre- photographed scene is located at the center for the video camera arranged on it, on lower 2 vertical directions.
Further, described that the video or image of acquisition are processed by VR standard according to visual angle, left eye, right eye
The step of spherical video or image of images of left and right eyes further comprises step：
By the front, rear, left and right visual angle left eye of acquisition, the video or image of upward angle of visibility and downwards angle of visibility are processed into VR standard
Left eye spherical video or image；
By the front, rear, left and right visual angle right eye of acquisition, the video or image of upward angle of visibility and downwards angle of visibility are processed into VR standard
Left eye spherical video or image.
Further, the focal length of all video cameras is arranged between 18mm to 15mm.

Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Inventor observes：The panoramic video of common VR video（Or image）It is to be distinguished using single video camera
From up, down, left, right, before and after, six direction is shot, then uses dedicated Software Create spherical shape video or horizontal exhibition
The flat image opened.
By analysis, panoramic video of inventor's discovery due to shooting（Or image）Only there is the information of an eyes,
Human eye can not be allowed to judge the angle information of distance, therefore common VR video does not have 3D effect, not have 3D and feel.
By analysis, inventor thinks to be in place of the VR video that there is 3D to feel is different from common VR video：With 3D
The VR video of sense needs to provide individual panoramic video to the images of left and right eyes of people respectively, allows human eye that can really experience distance.
The present invention proposes a kind of camera pedestal equipment, method, and the 3D shooting of the VR video using the camera pedestal equipment, method
Method can obtain the VR video with 360 degree of real 3D senses and meet and use to overcome technical problem in the prior art
The demand at family, and method of the invention implements very simple, is easy, application easy to spread.
