Abstract

The invention relates to a making and display technology of a dynamic stereopsis, wherein two sets of stereopsis shot or made at different angles are divided and synthesized to be output to a display device; every two adjacent columns of display pixel points of the display device respectively display the content of the two sets of stereopsis; after the display screen of the display device is provided with a grating, an observer can directly watch a vivid stereopsis.

Description

A kind of making of dynamic 3-D video and Display Technique

Technical field

The present invention relates to filming image and synthesis technical field, Display Technique field.

Background technology

Present stereoscopic TV and film want the beholder to be with special spectacles just can see, be not suitable for arbitrarily watching in public, and the raster pattern relief painting are static, and be not enough to spectators' attraction.

Summary of the invention

The invention provides a kind of making and Display Technique of dynamic 3-D video, with two video camera anthropomorphic dummies' eyes same things is taken from two different angles earlier and obtained two groups of dynamic images, or from same 3D digitized video, obtain two groups of dynamic images by two different angles outputs, or with TV, the image of one-shots such as film becomes two group images of two angle shots by technical finesse, this two group image is divided into staggered being synthesized together is shown on the screen again after the multiple row, after adding original screen panel on the display screen, the beholder just can directly see stereopsis true to nature within the specific limits.

The technical solution adopted for the present invention to solve the technical problems is: same things is taken from two different angles with two video camera anthropomorphic dummies' eyes and obtained two group image contents, or from same 3D digitized video, obtain two group image contents by two different angles outputs, or with TV, the image of one-shots such as film becomes two group images of two angle shots by technical finesse, again with every two field picture of this two group image by the wide multiple row that is divided into of pixel format that shows, the columns of picture segmentation is identical with the columns of the pixel format that picture shows, content with the even column of the content of the odd column of left side angular image and the right angular image, perhaps with the content of the odd column of the content of the even column of left side angular image and the right angular image, reconfigure and make the steric information image by returning original sequence of positions, like this when showing this steric information image, what the two every adjacent row pixels of display screen showed is respectively the content of original this two group images picture, the odd column pixel of display screen shows, and what be that the content even column pixel of left side angular image shows is the picture material of the right angle, and perhaps the odd column pixel shows, and what be that the picture material even column pixel of the right angle shows is the picture material of left side angle; Display device can be used computer monitor or liquid crystal TV set or the plasma TV etc. after the repacking, to be the vertical arrangement color effect better for the three primary colors of each pixel point during demonstration, it is horizontal that the three primary colors point of each pixel of existing display device all is, can before display screen, add an equal mating plate, the three primary colors of each pixel are mixed, perhaps the screen of existing display device is rotated 90 degree and use afterwards, making or also corresponding during output steric information image picture is being rotated 90 degree; A slit grating plate or column mirror grating plate are added in the display screen front, original screen panel can be adjusted to adapt to different viewing distances with the distance of display screen, average mark is furnished with many vertical blackstreaks and transparent stripe on the slit grating plate, blackstreak and transparent stripe are alternate to arrange, the width of blackstreak and the width of transparent stripe are proportional, the width of blackstreak is 2-10 a times of transparent stripe width, and the computational methods of the centre distance of adjacent two transparent stripes are:

There is the refraction striped of many wide vertical arc convex on column mirror grating plate surface, the focus of every refraction striped drops on the display surface of display screen, if display screen be equipped with equal mating plate then the focus of every refraction striped drop on the equal mating plate, the computational methods of width of every refraction striped are:

The computational methods of the viewing ratio of two kinds of gratings are identical, and computational methods are:

When showing this steric information image with this display device, because the printing opacity effect of the transparent stripe of slit grating plate and the barrier effect of blackstreak, perhaps because the refraction action of column mirror grating plate, beholder's left eye in the certain distance scope is seen the picture material of left side angle, right eye is seen the picture material of the right angle, thereby just can obtain stereo perception true to nature, show that continuously this steric information image just realized dynamic three-dimensional effect.

The invention has the beneficial effects as follows that the steric information image making is simple and easy, display screen installs the slit grating plate additional or the column mirror grating plate is also simple, and the beholder need not put on any equipment just can directly see dynamic 3-D video, and peculiar novelty also can be made into stereoscopic TV.

Embodiment

In Fig. 1, two video cameras (2) anthropomorphic dummy's eyes are taken same things from two different angles at a distance of certain distance, and the big more stereoeffect that shows at last of the differential seat angle of two video cameras is strong more.It is that the LCD of 1920*1080 is rotated 90 degree backs and used that display device is selected resolution for use, the image demonstration all over the screen of taking, like this two group images of taking are cut apart when synthesizing and just come five equilibrium to handle, take for placing behind rotatable 90 degree of two video cameras of cooperation display device by 1080 row.In Fig. 5, edit two width of cloth sizes with display screen the same big five equilibrium all over the screen 1080 patterns that are listed as, wherein the odd column of first width of cloth pattern is that blank even column is a black, the odd column of another width of cloth pattern is that the even column of black is blank, then on the picture of the image that first width of cloth pattern covers is photographed to the left side, on the picture of the image that another width of cloth pattern covers is photographed to the right, two groups of images are stacked up with perspective fashion just be merged into the steric information image again.

In Fig. 3, the slit grating plate sticks one deck grating film (5) by transparent materials such as sheet glass (4) and makes, many vertical blackstreaks and vertical transparent stripe are arranged on the grating film, blackstreak and transparent stripe are alternate to arrange, the width of blackstreak is 2-10 a times of transparent stripe width, and the centre distance of two adjacent transparent stripes is calculated by following formula by the width of the every row pixel of this display screen:

Original screen panel is attached to display screen (3) front of display, on this LCD during this steric information image of demonstration all over the screen, because the printing opacity effect of the transparent stripe of slit grating plate and the barrier effect of blackstreak, beholder's left eye in the certain distance scope is seen the image content of left side angle, right eye is seen the picture material of the right angle, thereby just can obtain stereo perception true to nature.This steric information image of demonstration has just been realized dynamic three-dimensional effect continuously.
