First embodiment
Fig. 1 is a work flow diagram of a server in a naked eye 3D video playing method provided by an embodiment of the present invention, the embodiment of the present invention provides a naked eye 3D video playing method applied to a server, the server may be a server, a computer, a cloud disk, and other devices, the server may establish a communication connection with a terminal playing a naked eye 3D video through communication methods such as the internet, a 4G/5G mobile communication network, and the internet of things, the method includes:
s101: and the server acquires a picture carrying 3D screen raster parameters sent by the client, wherein the size of the picture corresponds to the size of the 3D screen.
Specifically, a client for naked eye 3D video playing, that is, a terminal for playing video, may be a hardware device such as a smart phone, a handset, a tablet computer, a notebook, a computer, and a television, and these devices are correspondingly provided with APPs (applications) for playing naked eye 3D video. According to the difference of terminals playing naked-eye 3D videos, the terminals have different types and different sizes of 3D screens, and the grating characteristics, types, specifications, thicknesses and sizes of the 3D screens are also different, so that the 3D screens of different terminals have different image effects, and different grating parameters of the 3D screens are stored in the client.
Specifically, the grating parameters, types, specifications, thicknesses and sizes of different types and sizes of 3D screens are different. The grating parameters specifically refer to grating density, grating thickness, grating viewing distance, grating light transmittance, grating deviation value, and the like.
The grating image effects of different screens are different, the client stores grating parameters of different 3D screens, the grating parameters are made into a mapping table, and a picture with the same size as the screen is put in the mapping table.
The image is used as a carrier, raster parameter information of a screen can be recorded more conveniently, a server can correspond pixel points in a video source to physical positions on the image after receiving the image, and the video source is rendered more conveniently. The size of the picture is also representative of the size of the 3D screen selected.
S102: and 3D rendering is carried out on the video source by the server based on the picture, and the video file is obtained by re-recording in the 3D rendering process.
Specifically, after acquiring the picture carrying the 3D screen raster parameter, the server may render the naked-eye 3D video source to be played based on the picture.
It should be noted that the picture is equivalent to a table made according to raster parameters of the screen, and when rendering, the video source is split into one frame and one frame of images, and then each pixel on each frame of images is corresponding to a corresponding cell of the table, so as to complete rendering.
Specifically, different pixels have different parallaxes, which is a difference in direction resulting from viewing the same object from two points having a certain distance. And mapping according to different parallaxes of different image pixels in the rendering process, corresponding each image pixel to the grating parameter of the screen, and displaying the corresponding image pixel at the corresponding physical position of the picture.
And a new video file needs to be obtained by re-recording in the rendering process.
It should be noted that, recording a video file requires acquiring each frame of RGB image through opengl (open graphics library), and simultaneously converting the RGB image into YUV (a color coding method adopted by the european television system) and then performing video coding, wherein a specific process of converting one frame of RGB image into YUV is as follows:
both RGB and YUV are color spaces used to represent colors, and both may be converted to each other. The RGB color scheme is a color standard, and various colors are obtained by changing three color channels of red, green and blue and superimposing the three color channels on each other. Wherein R represents red, G represents green, and B represents blue.
YUV is mainly used to optimize the transmission of color video signals, and has the greatest advantage over RGB video signal transmission in that it takes up very little bandwidth (RGB requires the simultaneous transmission of three separate video signals). Wherein "Y" represents a gray scale value, which is a baseband signal; "U" and "V" denote chromaticity, which is used to describe the color and saturation of the image for specifying the color of the pixel. U and V are not baseband signals and U, V are quadrature modulated during processing. The RGB input signals create luminance by superimposing specific parts of the RGB signals together; the chrominance and saturation are represented by Cr and Cb, respectively, with Cr reflecting the difference between the red part of the RGB input signal and the luminance value of the RGB signal. And Cb reflects the difference between the blue portion of the RGB input signal and the same luminance value of the RGB input signal. Through operation, the mutual conversion between YUV and RGB can be realized, and the process is as follows:
Y'＝0.299*R'+0.587*G'+0.114*B'
U'＝-0.147*R'-0.289*G'+0.436*B'＝0.492*(B'-Y')
V'＝0.615*R'-0.515*G'-0.100*B'＝0.877*(R'-Y')
R'＝Y'+1.140*V'
G'＝Y'-0.394*U'-0.581*V'
B'＝Y'+2.032*U'
the YUV three components can be reduced to R (red), G (green) and B (blue), and the process is as follows:
Y'＝0.257*R'+0.504*G'+0.098*B'+16
Cb'＝-0.148*R'-0.291*G'+0.439*B'+128
Cr'＝0.439*R'-0.368*G'-0.071*B'+128
R'＝1.164*(Y'-16)+1.596*(Cr'-128)
G'＝1.164*(Y'-16)-0.813*(Cr'-128)-0.392*(Cb'-128)
B'＝1.164*(Y'-16)+2.017*(Cb'-128)
the symbols are provided with prime marks, which indicate that the symbols are gamma corrected on the basis of the original values.
In the process of recording the video, the RGB images captured one frame by one frame in the video source are converted into YUV through the conversion process, and then the video is encoded and recorded into a video file with a conventional format.
In the process of recording the video file, the RGB image is converted into YUV and then video coding is carried out to obtain a new video file, and the new video file is selected from conventional formats for storage such as AVI, WMV, MPEG, MKV, RMVB, MOV and the like.
S103: and the server sends the video file to the client for playing.
Specifically, the server can establish communication connection with a terminal playing naked eye 3D videos through communication modes such as the Internet, a 4G/5G mobile communication network and the Internet of things, and sends the video files to the client by using an FTP application layer protocol.

The video source is processed according to the grating parameters of the 3D screen, so that the effect of playing the video source by the 3D screens of different types and sizes is better, and the performance requirement of a naked eye 3D technology on the 3D screen is reduced.
In one embodiment, the server performs a 3D rendering step on the video source based on the picture, including:
s201: and the server displays the image pixels with different parallaxes in the video source based on the position of each point pixel point in the picture.
It should be noted that the server needs to read the corresponding raster parameters in the picture first, and then captures the image from the video source, where the process of capturing the image is to divide the video source into frames of images, capture each frame of image, and read the positions of the pixel points on each frame of image, and this process may be implemented by some languages or tools, such as Opencv, Matlab, Python, C languages, and the like. And then, displaying the grating parameter information of each point in the picture in one-to-one correspondence with the pixel points in the video source.
It should be noted that, in the process of capturing images from a video source, it is necessary to map the pixels of each frame of image in the video source conveniently according to the length, the number of frames, the number of sampling pixels, and other information of the video source.
This process, which requires grabbing a frame-by-frame image from a video source, may need to be implemented by some function, such as cvGrabFrame, etc.
It should be noted that the process of displaying the pixel of the image to the corresponding physical position of the picture needs to be completed by a program. The pixels in the image are accessed and if necessary, the assignment is modified through different functions, and the functions used include a cvGet2D () function, a cvSet × D function and the like.
In one embodiment, the server performs a 3D rendering step on the video source based on the picture, including:
s301: the server performs 3D rendering on the same video source based on different raster parameters of the picture, and the image results are different.
It should be noted that the pictures carry raster parameters of the 3D screen, and the corresponding pictures of different screens are different. Because different types and sizes of 3D screens have different characteristics, types, specifications, thicknesses and sizes, the grating density, the grating thickness, the grating visual distance, the grating light transmittance, the grating deviation value and the like of the grating are different.
