Description
Technical field
The present invention relates to bore hole 3D technology field, especially a kind of slit grating preparation method for bore hole 3D printings.
Background technology
Traditional stereo-picture display needs to wear the auxiliary of such as polarising glass, macyscope or liquid crystal glasses etc
Assistant engineer has, therefore human eye is occupied completely, and the eyes of people do other work unrelated with screen all ten in addition to watching screen
Divide inconvenience.The stereo display technique of wears glasses, it is inapplicable in many occasions although its stereo display effect is particularly excellent
's.Bore hole stereo-picture Display Technique is then without wears glasses, because stereoscopic display can be compatible with other two dimensional displays.
Due to user, eyes are unrestricted when three-dimensional display is watched, be it is entirely free on his, therefore, can carry out simultaneously except
Other work watched beyond display, so as to have greater flexibility and practicality.
Bore hole stereoscopic display technology mainly has two classes：Lens pillar technology, disparity barrier technology.Its principle of optical screen barrier technique
It is the baffle plate in front or behind one piece of fence type of placement of liquid crystal display, so blocking due to baffle plate, observer's is simple eye
The row pixel on display screen is can only see by a slit on baffle plate, as left eye can only see strange pixel column, and is seen not
Arranged to dual pixel；Equally, right eye can only see dual pixel row, and can't see strange pixel column.So, respectively by odd even pixel
The two images of composition are arranged just into the stereo pairs with horizontal parallax, by the fusion of brain, ultimately form one
Width has the stereo-picture of depth perception.
3D stereo-pictures show two kinds of spectacle and naked eye type.Spectacle wants used optical filter glasses viewing image,
It is that two-dimentional common color image is shown into software processing through aberration formula 3D, with the image of two kinds of different visual angles with red, Lan Huo
Red, green two kinds of colors are printed in the same painting face, are filtered by red, blue (right eye is red, left eye is blue) of anaglyph spectacles
Piece can just see 3D stereoeffects.This width picture filters through red, blue eyeglass, and red figure is blue by red eyeglass
For the figure of color by blue eyeglass, the different graphic that the eyes of left and right two are seen is overlapping in the brain to show the three-dimensional effects of 3D
Fruit.Wear glasses and see that 3D images are very inconvenient, have a small amount of application in children's book equipped, panel etc. at present.Naked eye type is that eye eye is direct
Image is watched, it is that two-dimentional common color image is printed on into paper after lenticular sheet 3D three-dimensional imaging software processings
On, then with the mounting of colourless transparent liquid glue at the lenticular sheet sheet material back side, i.e. direct viewing to 3D stereo-pictures.It is imaged
It is using lens pillar refraction catoptric imaging principle, the plane of delineation for making to print on paper is located on the focal plane of grating lens, this
Sample pixel of image below each lens pillar is divided into several sub-pixels, and lens just project per height picture in different directions
Element, because the left and right spacing of two causes some difference of the visual angle of two, and such differential seat angle can make two to observe sees image just
See the image of a little displacement formed by different subpixel, the overlapping fusion of image that the brain of people arrives soon by two, just
Produce spatial impression stereoscopic vision true to nature.The material of lenticular sheet is mainly PET, PP, PS, PVC, PMMA etc.,
The plate with some strength, piece, membrane material is made, is mainly used in the neck such as lamp box, advertisement, display and demonstration, wedding photo, decoration painting
Domain.
Imitated because bore hole 3D stereo-pictures Display Technique can allow people intuitively to arrive the 3 D stereo of objects in images
Fruit, application of this technology on clothes also have many difficulties, such as：It is frivolous, soft and have certain elastic, firm, resistance to
Wash, be wear-resisting, be wear-resisting, light transmittance and refractive index meet necessarily required lenticular sheet and are not easy to make again, Grating Film it is each
Precisely identical paste operation is extremely difficult for the grating fringe of individual lens pillar and graphic image picture on fabric, the printing opacity of bonding agent
Influence that rate, refractive index are shown to image and firmness etc., the difficult choosings of material of Grating requirements greatly and is reached due to operation difficulty.
Therefore, it is necessary to propose a kind of slit grating preparation method for bore hole 3D printings for above mentioned problem.
