Abstract
The invention discloses an implementation method of a 3D (three-dimensional) video file from a single video file. The implementation method comprises the following steps: getting an original image, wherein the original image is a frame of picture of the single video file; splitting the original image according to the storage mode of the original image to get a left-eye image and a right-eye image, which are independent; amplifying the left-eye image and the right-eye image to the size of the original image according to a Scaling algorithm to get the new left-eye image and the new right-eye image; and packing the new left-eye image and the new right-eye image for output and generating the 3D video file for playing. According to the implementation method disclosed by the invention, the single video file under the different storage modes can be transformed to the video file with a 3D effect, which supports the playing on a television, and the 3D file existing in a single file storage way can be transformed in a fast, flexible and high-efficient manner.
Description
Technical field
The present invention relates to the 3D technical field of video processing, particularly a kind of single video file is to the implementation method of 3D video file.
Background technology
Because fast development of information technology, the world has got into the epoch of information.Along with the fast development of computer technology in the last few years, the research and development of 3D technology and the stage of fumbling in early stage of using the decades of having passed by, the maturity of technology, sophistication, ease for use, hommization, economy etc. have all obtained huge breakthrough.The 3D The Application of Technology is popularized, and has towards the exploitation and the making of the culture and arts series products of visual performance classes such as video display animation, animation, recreation.Wherein, development of television has two very important trend: the high Qinghua from the SD to the high definition, and resolution can be increasingly high; Realize the 3D technology that stereoscopic vision is given sympathetic consideration to.Particularly the 3D technology is an important trend of TV tech development in a very long time in the future.
3D (Three Dimensions; Promptly three-dimensional) technology is to be implemented on the basis of original two-dimensional image to increase one dimension; The object seen of our eyes is three-dimensional at ordinary times; Differentiation about not only having on the plane also has the differentiation of front and back, distance, so feel that the object of seeing is three-dimensional.Produce this relief process: eyes are in observing scene; Because two eyes are at a distance of about 60mm, can be from two different viewed scenery, two images that arrive soon are also inequality; Will form parallax; Brain to two observed have nuance image handle, just formed far and near different depth effect, be three-dimensional sensation thereby produce scenery.
In the prior art; Eyes with two-way image unit anthropomorphic dummy are taken the two-way image, or the right and left eyes two-way image of computer generation, through making, broadcast, transmission; On the video screen that the modes such as time-division or polarization that are presented at last show; Viewers wear and the supporting glasses of 3D television set make right and left eyes watch the image of left and right sides image unit shooting respectively, thereby in brain, form the TV of stereoeffect.Yet; When transmitting and store,, then take a large amount of transmission bandwidths and memory space for the 3D video of playing on TV if the employing two paths of signals transmits and stores; Influence system speed; Therefore usually adopting the form of monofile to transmit and store, so how to be the image with 3D effect with the image transitions under the monofile memory module fast and efficiently, is exactly our current problem that will solve.
Summary of the invention
The invention provides the implementation method of a kind of single video file in order to solve above technical problem, specifically comprise to the 3D video file:
Obtain original image, said original image is a frame picture of single video file;
Memory module according to said original image splits said original image, obtains two independently right and left eyes images;
According to the Scaling algorithm said right and left eyes image is amplified to the size of said original image, obtains new right and left eyes image;
With said new right and left eyes image packing output, generate the 3D video file and broadcast.
Wherein, the memory module of said original image specifically comprises:
Horizontal Tile SideBySide pattern is specially: deposit the half-resolution image that two frame resolution are 960*1080 side by side about in the full HD frame that resolution is 1920*1080; Or,
Over/Uder pattern vertically is specially: deposit the half-resolution image that two frame resolution are 960*1080 vertically in the full HD frame that resolution is 1920*1080.
Wherein, when the memory module of said original image was horizontal Tile SideBySide pattern, said memory module according to said original image split said original image, obtained two independently right and left eyes images, specifically comprised:
Said original image is got the first from left half data and a right half data splits, and the resolution of said original image is 1920*1080, and the resolution of a said the first from left half data and a right half data is 960*1080.
Wherein, the memory module of said original image is during for Over/Uder pattern vertically, and said memory module according to said original image splits said original image, obtains two independently right and left eyes images, specifically comprises:
Said original image is got a last half data split with next half data, the resolution of said original image is 1920*1080, and the resolution of a said last half data and next half data is 1920*540.
Wherein, the Scaling algorithm is specially convolution difference algorithm 3 times.
Wherein, with said new right and left eyes image packing output, generate the broadcast of 3D video file and also comprise afterwards:
Detect said 3D video file and whether have 3D effect,, then normally broadcast if having; If do not have, then said new right and left eyes image sequence to be put upside down, packing output generates the 3D video file and broadcasts.
Compared with prior art; The embodiment of the invention has the following advantages: through the single video file under the different memory modules is converted into the video file with 3D effect that support is broadcasted on TV, and can be fast, flexibly, efficiently the 3D file that exists with the monofile storage mode is transformed.
