Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The realization of the present invention is described in detail below in conjunction with specific embodiment.
The running environment frame diagram of LAN VR live broadcasting methods provided in this embodiment.
Fig. 1 shows the running environment frame diagram of LAN VR live broadcasting methods provided by the invention, running environment as shown in Figure 1
Including：
Space can be distributed at court's trial scene or meeting scene, personnel from all directions, we can arrange multiple camera shootings
Head, just at least need two cameras that can take entire court's trial scene or meeting scene, in order to reach better effect, one
As can arrange more than two camera, and the same height level of multiple cameras is uniformly distributed；One group picture of camera acquisition
If piece all transmits, need that the one group picture piece is transferred to stitching server with optical fiber, by stitching server by one group
Picture is spliced into a two-to-one image of length and width, stitching server by an image transmitting to VR, not in court's trial or meeting
The personnel for discussing scene can also implement to see the situation at scene by VR.
Fig. 2 shows the flow chart for the LAN VR live broadcasting methods that another embodiment of the present invention provides, one kind as shown in Figure 2
Input method includes the following steps：
In step S201, one group of image is acquired, one group of image includes at least two images.
It should be noted that acquiring one group of image here needs with multiple cameras, at least two cameras, acquisition one
Group picture piece also includes at least two pictures；But in order to reach clearer effect, we can generally use more than two to image
Head is acquired, and camera is located at same level height and is uniformly distributed, and above-mentioned arrangement is provided to better vision
Effect.
Explanation is needed further exist for, the necessary synchronous acquisition image of camera of above-mentioned one group of photo of acquisition can be kept away in this way
It is separated that exempting from, which has the personnel's body for occurring not splicing or occurring splicing when personnel's movement, to realize synchronization
The purpose of image is acquired, same controller may be used and control the multiple cameras described above arrived.
Need further exist for explanation, although we have seen that video, in fact be acquisition a frame frame image.
Explanation is needed further exist for, because of the collected multiple image of multiple cameras, the bandwidth of such simultaneous transmission
It is required that higher, optical fiber or multiple coaxial cables may be used to carry out image propagation in we, and image transmitting is taken to splicing
Business device.
In step S202, one group of image is spliced into a two-to-one image of length and width.
It should be noted that image mosaic needs to consume vast resources, we carry out generally in stitching server.
In step S203, an image is pasted into spherical day sylphon, forms spherical day sylphon textures.
It should be noted that spherical day sylphon here can be one or two, at present generally in order to build
Binocular parallax, typically using two spherical day sylphons, epigraph is all pasted in two spherical days sylphons the inside.
In step S204, according to the quantity of spherical day sylphon, it is set to the consistent virtual camera of the quantity.
It should be noted that in step S204, if there are one spherical day sylphons, we just need setting one virtually to take the photograph
Camera, if there are two spherical day sylphons, it is necessary to set two virtual cameras.
Explanation is needed further exist for, virtual camera is located at the geometric center of spherical day sylphon, if there are one spherical
Its sylphon just sets a virtual camera, and the virtual camera is located at the geometric center of spherical day sylphon；If there is two
A spherical shape day sylphon, just sets two virtual cameras, and above-mentioned two virtual camera is located at two spherical day sylphons respectively
Centre, virtual camera surround the geometric center rotation of spherical day sylphon.
The above method acquires image by synchronous multi-angle, overcomes site environment transformation problem, is transmitted by optical fiber
Image overcomes the problem of super large image transmitting loses data or delay, has ensured that image effectively transmits, and carried out image
Splice and paste spherical day sylphon, virtual camera is set for spherical day sylphon, realizes and is showed by VR solid show court's trials
Or meeting scene, viewing personnel can with full views watching angled personnel situation, and the sense of reality is very strong.
Further, the above method further includes：
Super sampling is carried out to the spherical day sylphon textures, forms sample objects；
The sample objects are placed in the visual field of the virtual camera.
By way of above-mentioned super sampling, viewer is allowed to feel apparent, truer.
Fig. 3 shows the structure chart of LAN VR live broadcast systems provided by the invention, a kind of input system packet as shown in Figure 3
It includes：
Collecting unit 31, for acquiring one group of image, one group of image includes at least two images；
