The screen viewport size of panoramic video player；And
According to the size and starting position coordinates of each split screen window in the split screen of left and right, the plane panoramic video stream is plotted to
On the screen of the panoramic video player, to realize that panoramic video is played.
According to an embodiment of the present invention, wherein, it is described split by spherical angle obtain the 2D spherical models, and
The step of generation sphere vertical array, includes：With longitude 360, the 2D spherical models are divided into several spheres by latitude 180,
And the sphere summit of each sphere is calculated, to generate the sphere vertical array.
According to an embodiment of the present invention, wherein, the corresponding grid in visible grid set described in the textures
In texture the step of include：Video image is divided into the coordinate corresponding with the sphere vertical array, and is corresponded, covered
The texture of the network is covered, the visible grid set of the threedimensional model is formed.
According to an embodiment of the present invention, wherein, the screen viewport size refer to screen width with height.
According to an embodiment of the present invention, wherein, the width of the screen viewport size is highly constant divided by 2, obtains
The width and the starting position coordinates of each split screen window in the left and right split screen.
The player method of panoramic video provided in an embodiment of the present invention, is mapped to by spherical by plane video image
Change the spherical pictures of 3D that mapping treatment is obtained, complete image rendering, the image for showing is accurate and real-time, and by spheroidization
Mapping, when the visual field changes, image mapping distance keeps constant.
Brief description of the drawings
Fig. 1 is the flow chart of one embodiment panoramic video player method
Specific embodiment
Below according to accompanying drawing and specific embodiment a kind of VR virtual realities panoramic video player method of the invention is done into
Elaborate to one step, in the hope of providing a clearer understanding of its working method and using step, but this can not be limited with this
The protection domain of patent of invention.
With reference to Fig. 1, Fig. 1 is that a kind of flow of VR virtual realities panoramic video player method provided in an embodiment of the present invention is shown
It is intended to.
As shown in figure 1, the step of virtual reality panoramic video player method, the method is as follows:
Step S101, is shot to existing view by capture apparatus and obtains plane panoramic video stream；
Step S102, the plane panoramic video stream is obtained by panoramic video player, and by the plane panoramic video stream
Frame of video is decoded into, wherein, panoramic video player can be arranged on mobile terminal, PC ends, VR headset equipments or all-in-one
On.Planar video stream is decoded into each two field picture by panoramic video player by decoding process.
Step S103, the horizontal direction angle of visual field and the vertical direction angle of visual field of the taking lens according to the capture apparatus are built
Vertical 2D spherical models.
Step S104, is split by spherical angle and obtains the 2D spherical models, and generates sphere vertical array, wherein,
