Technical field
The present invention relates to Naked eye grid 3D photo fields, specifically a kind of Naked eyes grid 3D photos automatic contraposition device and right
Position method.
Background technology
Bore hole grating 3D photo displaying principles are as follows：
A) as shown in figure 1, Naked eyes grid 3D photos are made up of " Naked eyes grid " with " 3D photos printing paper " two parts；As shown in Fig. 2
After bonding, the cross section of 3D photos.
B) as shown in figure 3,3D rendering on 3D photo printing paper, by multiple different visual angles（view1、view2、view3….）
Image composition, the image at each visual angle is a plurality of vertical stripe, corresponding to grating pitch by regular cycles arrangement.
C) as shown in Figure 4,5, bore hole grating 3D photos, will such as show normal 3D effect, and 3D rendering must with grating fringe
Upper figure best alignment position must be pressed.Situation in lower two figures, can not all show normal 3D effect.
D) grating requires very high with 3D photos aligning accuracy.
With 75 lines（75 grating fringes of per inch）Exemplified by grating, 19 multi-view images, 4*6 inches of 3D photos of banner：
。
With a length of radius of 4*6 inch photo vertical edges, its summit rotates the arc length of a multi-view image width,
。
In theory, the error range of normal 3D effect permission is：
Horizontal error scope is：±0.009mm

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
The Naked eye grid 3D photo automatic aligning methods of the present invention, its automatic aligning principle is as follows：
First, as shown in fig. 6, setting a plurality of vertical to bit line in the appropriate area of 3D photo printing paper.
To bit line setting principle：
A) it is identical with grating pitch used to bit line spacing；
B) every to bit line line thickness, is not more than；
C) it is the integral multiple of grating pitch to bit line to 3D rendering center line apart from P1；
2nd, as shown in fig. 7, after contraposition is accurate, grating and the position relationship to bit line.
Now, due to the amplification of grating R circular arcs, when artoregistration line vertical direction is observed, to the Zone Full of bit line
It is changed into all most black.Effect is as shown in Figure 8.
As described and depicted in figs. 9-13, such as contraposition slightly deviation, then can not observe upper figure to the whole most black effects in bit line region.
And deviation is bigger, it was observed that lighter to the black region of bit line or fewer.
As shown in figure 14, Naked eye grid 3D photo automatic contraposition devices of the invention, including first, second pair of bit line detection
Element D1, D2, first aligns line detection devices D1 the first detection zones of detection A1, the second contraposition line detection devices D2 detections
Second detection zone A2, the first detection zone A1 diameters are not more than all to bitline width；Second detection zone A2 width is little
In all to bitline width, highly not less than 1/2 to bit line height.Also include the level fortune of control grating horizontal motion
Motivation structure M1, and the rotating mechanism M2 that control grating rotates around the first contraposition line detection devices D1 axis " O ".
As shown in figure 15, first, 3D photo printing paper is fixed, horicontal motion mechanism M1 control gratings do horizontal direction fortune
It is dynamic.It was observed that be to bit line situation of change：Black portions are moved up and down, but black portions vertical height is constant.Meanwhile, first
Align line detection devices D1 and detect the first detection zone A1.
As shown in figure 16, when a black portions enter the first detection zone A1, and it is maximum to occupy the first detection zone A1
During area, it is most black that the first contraposition line detection devices D1 detects the first detection zone A1, horicontal motion mechanism M1 stoppings action.This
When the first detection zone A1 positions it is accurate.
Rotating mechanism M2 control gratings do the rotary motion of the axis O around the first contraposition line detection devices D1.Second
Detecting element D2 detects the second detection zone A2.
Now, it was observed that to bit line black portions vertical height, become big according to M2 direction of rotation or diminish.As schemed
Shown in 17,18, meanwhile, the center of the first detection zone A1 black portions is motionless.
As shown in figure 19, control rotating mechanism M2 direction of rotation, makes the second detection zone A2 black portions to vertical
Height augment direction changes, until all the second detection zone A2 reaches most black, contraposition completion.
