The bore hole 3D display effect method of testing that the embodiment of the present invention provides, the effective bore hole 3D display effect of test display apparatus, for guaranteeing that the quality of display unit provides assurance.

Display unit is when realizing a width bore hole 3D picture, in this picture, generally include left eye picture and right eye picture, by utilizing two characteristics with parallax of people, thereby without any need for auxiliary equipment (as 3D glasses, the helmet etc.) in the situation that, present solid, bore hole 3D picture true to nature.

So, in the embodiment of the present invention, in order to obtain the first view (specifically can be the effective display frame of left eye or right eye) at the white chromatic value at different points of view place, the first view in can a width 3D picture is set to complete white view (specifically can realizing by the adjustment of display parameters), and other views except the first view are set to full blackout figure, thus the impact of the brightness that can avoid other views on the first view white chromatic value test result.

Then as shown in Figure 2, the viewing ratio (S1) that testing equipment (as luminance meter and optic test platform etc.) is placed in to display unit is located, and testing equipment is central over against display screen, take display screen center (O point) is the center of circle, one viewing ratio S1 is radius, by clockwise or inverse clock direction of rotation, respectively for example, at different points of view (P in accompanying drawing 2 ₁, P ₂, P ₃, P ₄, P ₅shown in position) locate the first view to carry out white colourity test (also can carry out luminance test simultaneously, when obtaining brightness value, obtain white chromatic value), to obtain the first view in the white colourity at different points of view place.

Visible, in the embodiment of the present invention, obtain the first view in the 3D picture that display screen shows and specifically can comprise in the process of the white chromatic value at different points of view place:

The first view in 3D picture is set to complete white view, and other views in 3D picture are set to full blackout figure, and the first view is left eye or the effective display frame of right eye in 3D picture;

Take display screen center as the center of circle, and viewing ratio is radius, by a preset rotation direction, at different points of view place, the first view is carried out to white brightness test, obtains the first view at the white chromatic value at different points of view place.

Due in an alternate embodiment of the present invention, can be when carrying out white chromatic value test, carry out the test of brightness value, to obtain the brightness value at the different points of view place that the first view is corresponding, therefore, in the embodiment of the present invention, the first view that can also be based on obtaining, at the brightness value at different points of view place, builds described the first view at the brightness distribution curve at different points of view place.This brightness distribution curve specifically can be as shown in Figure 3, wherein, mark 1,2,3,4 corresponding curves, be respectively the first view, the second view, three-view diagram, the corresponding brightness distribution curve of the 4th view, be in the embodiment of the present invention, can, by repeatedly testing, obtain white chromatic value and the brightness value of different views in bore hole 3D picture.

In the present invention's one specific embodiment, obtain after the white chromatic value at the first view different points of view place, can, by tabling look-up, such as by modes such as comparison CIE1976 color tables, determine the first abscissa (u of view different points of view place white chromatic value in color table _i') and ordinate (v _i') information, and utilize this coordinate information to represent the white chromatic value at different points of view place, for example P ₁the white chromatic value of point can be expressed as (u ₁', v ₁'), the white chromatic value that P2 is ordered can be expressed as (u ₂', v ₂'), P _ithe white chromatic value of point can be expressed as (u _i', v _i'), the white chromatic value of other viewpoints is similar.

Then, can, by following computing formula, calculate the white colour difference of adjacent viewpoint:

$\mathrm{\Δ}{u}_i^{\′}{v}_i^{\′}=\sqrt{{(u_{i+1}^{\′}-u_i^{\′})}^2+{(v_{i+1}^{\′}-v_i^{\′})}^2}$

Wherein, u _i' represent (P for example of the first viewpoint in adjacent viewpoint ₁point) white chromatic value abscissa in chromatic diagram, v _i' represent the ordinate of described the first viewpoint white chromatic value in chromatic diagram; u _i+1' represent (P for example of the second viewpoint in adjacent viewpoint ₂point) white chromatic value abscissa in chromatic diagram, v _i+1' represent the ordinate of described the second viewpoint white chromatic value in chromatic diagram.

In an alternate embodiment of the present invention, the white colour difference that can calculate the first view adjacent viewpoint of obtaining is ordinate, and visual angle (θ) is abscissa value, makes adjacent viewpoint colourity change curve, specifically can enter as shown in Figure 4.The visual angle that the embodiment of the present invention is related, as shown in Figure 2, specifically can be a viewpoint (for example P2) to the straight line between described display screen central point, and the angle θ between the display screen central point vertical line (if P3 point is to the straight line between the O of the center of circle) of drawing.

After the white colour difference of the first view adjacent viewpoint is obtained in calculating, this difference that can be based on obtaining, determines bore hole 3D display effect

Because the white colour difference of adjacent viewpoint is less, the white chromatic value that adjacent two viewpoints are described is more approaching, beholder watches the impression of bore hole 3D picture more approaching in different points of view place, the display quality that so can show bore hole 3D picture is better, therefore, in the present invention's one specific embodiment, can based on adjacent viewpoint white colour difference with zero between relation, determine bore hole 3D display effect.And the white colour difference of adjacent viewpoint is more approaching zero, shows that bore hole 3D display effect is better, while equalling zero, can be optimal display result.

And in another specific embodiment, the technical scheme that the embodiment of the present invention provides can also, based on adjacent viewpoint white colour difference, be calculated three-dimensional viewpoint colourity variable quantity, and based on three-dimensional viewpoint colourity variable quantity, determine described bore hole 3D display effect.

The computing formula of the three-dimensional viewpoint colourity of described calculating variable quantity is:

$S=\sqrt{\frac{1}{n-1}\underset{i=1}{\overset{n}{\mathrm{\Σ}}}{(\mathrm{\Δ}{u}_i^{\′}{v}_i^{\′}-0)}^2}$

Wherein, S represents that described adjacent viewpoint white colour difference is with respect to zero dispersion degree.

Be in the embodiment of the present invention, can obtain adjacent viewpoint white colourity difference and be equivalent to zero dispersion degree S, because this S value can be evaluated the intensity of variation of the white colourity of adjacent viewpoint in bore hole 3D picture, therefore, can, based on this intensity of variation, determine the display effect of bore hole 3D.And same, S value is less, and the intensity of variation of making chroma color clear is less, and bore hole 3D display effect is better.
