The method disclosed by the invention has the beneficial effect of providing a simple algorithm which utilizes the 3D film source to generate the 3D visual effect; and a test proves that the method is easy to realize, the effect is obvious and a foundation for adding a more complicated algorithm is laid.
Description
Technical field
The present invention relates to the method that a kind of 3D of utilization film source produces the 3D visual effect.
Background technology
The human observed world is three-dimensional, and this is because two eyes object from different positions and angular fixation, on the left of left eye was seen, right eye was seen the right side, and the impression on two sides, the left and right sides closes messenger must arrive the stereo perception to it.Cause that this stereo effect is called " vision displacement ".When observing an object simultaneously with two eyes on the object every bit two eyes are all had a subtended angle.Object is near more from eyes, and every bit is big more to the subtended angle of eyes on it, and parallactic displacement is also big more, and this just parallactic displacement makes the distance of our ability differentiation of objects, and obtains to have the third dimension of the degree of depth.For object away from us; Two sight line almost is parallel, and parallactic displacement approaches zero, so we are difficult to judge the distance of this object; More can not produce stereo perception to it; Hope starry sky night as if you can feel that all stars in the sky all on same sphere, are hard to tell distance, and parallactic displacement that Here it is is zero result that causes.
Along with the development of 3D TV tech is swift and violent, obtained the concern of More and more factories.And high definition or full HD resolution TV is universal; And the low solution that reaches problems such as visual fatigue of resolution; The 3D monitor market will enlarge rapidly; But 3D TV existing market is also smaller, is in product and application of special occasions on a small scale, also needs variety of issues such as workout cost, colour cast, visual fatigue apart from scale of mass production.
Summary of the invention
The purpose of this invention is to provide the method that a kind of 3D of utilization film source produces the 3D visual effect, both realization and effect were obvious easily.
A kind of method of utilizing the 3D film source to produce the 3D visual effect; Its special feature is; Comprise the steps: to adopt the 3D video that forms by the twin camera lens shooting; Thereby two two field pictures that this twin camera camera lens is taken formation at one time are adjusted to respectively with whole screen display is measure-alike frame frequency is doubled, this two two field pictures Alternation Display is outputed on the whole screen cooperates with fast gate-type 3D glasses, thus the formation 3D effect.
If a frame 3D rendering is looked like to form by left and right two picture groups; To adjust to screen display image spreading measure-alike so; Specifically be that former the 1st row the 1st pixel is presented on the 1st on screen and the 2nd pixel; Former the 1st row the 2nd pixel is presented on the 3rd and the 4th pixel, and the rest may be inferred, and every provisional capital is done identical processing and got final product.
If a frame 3D rendering is looked like to form by upper and lower two picture groups; To adjust to screen display image spreading measure-alike so; Specifically be to be listed as the 1st pixel with the former the 1st to be presented on same column the 1st and the 2nd pixel; Be listed as the 2nd row pixel with the former the 1st and be presented on the 3rd and the 4th pixel of same column, the rest may be inferred, and every row are all done identical processing and got final product.
The beneficial effect of the inventive method has provided the simple algorithm that a kind of 3D of utilization film source produces the 3D visual effect, and through evidence, it is easy to realize, and effect is obvious, also lays a good foundation for adding more complicated algorithm.

Accompanying drawing 1 is for being used to realize the hardware principle block diagram of 3D rendering processing method of the present invention;
The frame 3D rendering that accompanying drawing 2 is made up of left and right two picture group sheets;
Accompanying drawing 3 is to be expanded by accompanying drawing 2 to accomplish later image;
The frame 3D rendering that accompanying drawing 4 is made up of upper and lower two picture group sheets;
Accompanying drawing 5 is to be expanded by accompanying drawing 4 to accomplish later image.
Embodiment
About the primary signal film source of present existing 3D is divided or up and down two groups of signals are exported simultaneously; Wherein the left side of (TV) screen is the picture of left camera shooting angle; The right of screen is the picture of right camera shooting angle; The image of taking two cameras is simultaneously displayed on the left half court and the right half court of TV, and this is the initial configuration of 3D film source.
And the inventive method can be watched 3D effect for the naked eyes that make the people; Need adjust to left half court and right half court (or the first half and second half) picture all over the screen; And Alternation Display appears at people's left eye and right eye, cooperates a fast gate-type 3D glasses left side to open the right side and closes, and the right side is closed a left side and opened; Thereby make human eye can watch the stereoeffect of 3D, as shown in Figure 1 is the hardware principle block diagram of realizing the 3D signal processing method.
Embodiment 1:
In the prior art frame 3D rendering by about or up and down two picture group sheets forms, want to realize that 3D effect just must separate two picture group sheets, if the right and left eyes image, then two picture groups on average account for half of screen, and are shown in Figure 2 for for example with right and left eyes:
As can be seen from the figure the image of left eye and right eye respectively accounts for the half the of screen, and difference slightly, now will be the image spreading of left eye to whole screen; Concrete grammar is exactly that former the 1st row the 1st pixel is presented on the screen on 1,2 pixel, and former the 2nd pixel is presented at 3; On 4 pixels; The rest may be inferred, and identical processing is done in every provisional capital, and it is as shown in Figure 3 to handle later effect.
As shown in Figure 3; Be exactly that left eye is expanded the later image of completion; It is identical that half the pixel is arranged in this width of cloth image; So when showing output, can be simultaneously displayed on data on two pixels, double thereby accomplish the image display frequency, the refresh rate of screen also just promotes one times.The processing method of right eye is consistent with left eye, therefore repeats no more.
As shown in Figure 4; If eye pattern sheet up and down; Then processing method is similar, and the 1st row pixel of former the 1st row is presented at the pixel of same column the 1st row and the 2nd row, and the 3rd row and the 4th that the 2nd row pixel of former the 1st row is presented at same column is gone on the pixel; The rest may be inferred, and each row is all done identical processing, and it is as shown in Figure 5 to handle later effect.
No matter figure or go up figure below about being handles the original clock frequency in back and does not become, and is repetition because image has half the pixel; So the pixel output variable doubles under the same frequency; Can export right and left eyes two two field pictures under the same time, thereby realize frequency multiplication, the right and left eyes image in order Alternation Display on screen; The synchronizing signal that cooperates the 3D glasses forms the 3D stereoeffect.
