Description
Technical field
The present invention relates to the bore hole stereo display technique, relate in particular to a kind of tracking mode bore hole stereo display control method, display control unit and corresponding display equipment, display system.
Background technology
Present stereopsis display mode is broadly divided into 3 types, and promptly spectacle, head-mounted display (Head Mount Display) formula and this paper are with the bore hole formula of introducing.The bore hole formula comprises numerous species, adopts realizations such as lens arra formula technology, parallax obstacle type technology usually.Mainly (Two-Dimensional, 2D) flat-panel screens (comprising LCD, plasma display, Field Emission Display and display of organic electroluminescence etc.) cooperates light-splitting device such as grating to assemble to the bore hole 3 d display device by two dimension.The grating that uses can be divided into slit grating and cylindrical grating, and accordingly, raster pattern 3D three-dimensional display also has two kinds of implementations: slit grating formula 3 d display device and microlens array 3 d display device.Yet slit grating blocks part light inevitably, causes the reduction of light utilization efficiency.And cylindrical grating is because the cause of self material, and focal length, pitch parameters such as (PITCH) all are fixing and nonadjustable.To above-mentioned defective, industry has proposed adjustable liquid crystal lens (LC-Lens), the liquid crystal grid controlled light-splitting devices such as (LC-Barrier) of parameter again.For example, liquid crystal lens distributes through changing voltage owing to be to be powered up to drive by strip electrode and electrode layer to form, and lens unit is moved, and can also change the pitch and the focal length of lens unit.
In diversified bore hole formula stereo display technique, what begin at first to develop is eyes (or claiming 2 viewpoints) modes.After the eyes mode, many more ultra many viewpoints modes of (or claiming many viewpoints) mode, panorama (ray space reproduction) mode and viewpoint number are developed out in succession.
A very big defective of bore hole formula stereo display is to receive the restriction of watching scope.Bore hole 3 d display device with the band grid of supporting 4 viewpoints is an example; Shown in Figure 1 is from obtaining perpendicular to display floater and the direction intercepting that is parallel to the display floater width, having drawn a part of display floater in the three-dimensional display (imaging plane) 10 and light-splitting device 20.The origin of coordinates of reference axis shown in Figure 1 is defined in the display screen center.The X-direction of this reference axis is also referred to as laterally, and Y direction is also referred to as short transverse, and the Z axle is also referred to as fore-and-aft direction, and the Z coordinate figure is also referred to as viewing distance.
As shown in the figure, be arranged with the display unit 101 of 4 visual point images on display floater such as the liquid crystal panel, by 1,2,3; 4,1,2,3,4; ... mode circulate and be staggered, be denoted as 1,2,3,4 display unit and be respectively applied for the image that shows the 1st viewpoint, the 2nd viewpoint, the 3rd viewpoint and the 4th viewpoint.In two adjacent display units, one is used to show the image that offers beholder's left eye, and another is used to show the image that offers beholder's right eye.In the literary composition with the width W of 4 continuous display units
dBe called a display unit and arrange cycle W
Td(under the N viewpoint W
Td=N*W
d).Display unit in the literary composition is a logical concept, can be time pixel or pixel, but be not limited thereto, and as also being that two pixels are a display unit, perhaps thinner inferior pixel segmentation again is called time time pixel etc.
Branch light action through the spectrophotometric unit on the light-splitting device 20 201 (spectrophotometric unit of Fig. 1 is a grill unit on the three-dimensional filter, also can be the lens unit etc. in the lens arra) can spatially form the subarea of watching of staggered each visual point image of circulation.Be labeled as among the figure 1,2,3,4 watch that subarea 30 shows the 1st, 2,3,4 visual point images respectively watch the position of subarea on viewing ratio (or be called fit see distance).Fig. 2 a shows among Fig. 1 the lateral attitude corresponding to continuous 4 exemplary shapes of watching the subarea at display screen center, and inner the sign has 1,2,3; 4 quadrangle is represented the subarea of watching of the 1st, 2,3,4 visual point images respectively; Be quadrangle, can see the 1st, 2 respectively; The image that the display unit of 3,4 visual point images appears, line segment BD representes the position of viewing ratio.The subarea of watching of other positions also is a quadrangle, and is slightly variant.Watching the subarea to be called one for 4 of the 1st, 2,3,4 continuous visual point images watches the subarea group, watches the width W of subarea group on viewing ratio for one
TwEqual 4 and watch the width 4*W of subarea on viewing ratio
w(W under the N viewpoint
Tw=N*W
w), W
wBe interocular distance.Should be noted in the discussion above that if adopt the grating that tilts on the XZ plane of the differing heights of display floater, there is lateral shift in the display unit of each visual point image.
Images of left and right eyes be in respectively the 1st, 2 viewpoints or the 2nd, 3 viewpoints or the 3rd, 4 visual point images watch in the subarea time, left eye is seen left-eye image, right eye is seen eye image, and generation is faced, and can watch the stereo display effect.And if images of left and right eyes be in respectively the 4th, 1 visual point image watch in the subarea time, will produce contrary looking.If when images of left and right eyes just is positioned at two borders of watching the subarea, can produces and crosstalk.The subarea of watching according to each visual point image can confirm that the positive vision area of adjacent viewpoint image reaches contrary vision area, crosstalk zone; Fig. 2 b shows the positive vision area and the contrary vision area of watching adjacent viewpoint image in the group of subarea shown in Fig. 2 a; The inner left eye that indicates when having 1,2 quadrangle to represent that place between the eyebrows is positioned at is wherein watched the 1st visual point image and the positive vision area of eye viewing to the 2 visual point images, and indicating has 2; 3 and 3,4 quadrangle similarly.And the inner left eye that indicates when having 4,1 quadrangle to represent that place between the eyebrows is positioned at is wherein watched the 4th visual point image and the contrary vision area of eye viewing to the 1 visual point image.On viewing ratio, the width of above-mentioned positive vision area and contrary vision area is W
w
More than be to be example with 4 viewpoints; When the viewpoint number is N; N >=2; Number, a number of watching the subarea of watching the subarea group to comprise of the display unit that comprises in display unit arrangement cycle are N, can form positive vision area and 1 contrary vision area of N-1 adjacent viewpoint image, and shape also is a quadrangle.
Utilize head tracking technology (being also referred to as the face tracking technology) can effectively alleviate limited this defective of bore hole formula stereo display viewing areas, it is a lot of to make viewing areas increase.The maximum characteristics of head tracking technology are can detect beholder's position (position such as the three-dimensional coordinate that refer to beholder's eyes or place between the eyebrows are perhaps for inferring the relevant position of beholder's eyes or place between the eyebrows position) in real time and offer display control unit; Display control unit can make the beholder enjoy the stereo display effect according to the display parameters of beholder's position change display.
Industry has been developed the head tracing system of cutting apart conversion grid (Shift Barrier) mode by name for a long time.This system is the constantly development of interim ground, developed again by 1997 can be when the beholder moves the technology of switching right and left (LR) image.Be placed with parallax barrier before the liquid crystal panel, can the left eye in the three-dimensional view be separated with image (being also referred to as right image) with image (being also referred to as left image) and right eye, make left image get into beholder's left eye, right image enters into beholder's right eye.As shown in Figure 3; When the beholder has been moved to the left when being equivalent to its interocular distance such as 65mm; This moment, the left and right image seen at first of beholder can exchange, and left image gets into beholder's right eye and right image enters into beholder's left eye, and this state is called " contrary looking "; The beholder can not produce correct stereoscopic vision, can not enjoy the stereo display effect.This moment can the switchable liquid crystal panel on the demonstration (, be equivalent to squinted half display unit of display unit and arrange the distance in cycle) of left image and right image to the double vision dot system, just can guarantee that the beholder continues generation stereoscopic vision.Developed the laterally conversion grid technology of Movable grid position in 1999 again.As shown in Figure 4, when lateral shift took place for beholder's position, if only moved the half the of interocular distance, for example during 32.5mm, the images of left and right eyes that the beholder can be taken place was seen right image and left image simultaneously, crosstalk phenomenon promptly occurs.In this case, only need Movable grid slightly, just can eliminate and crosstalk.
Being illustrated as of this process is shown in Figure 5, and the picture left above shows the beholder and moves preceding position among Fig. 5, and this moment, beholder's place between the eyebrows was arranged in positive vision area, can produce correct stereoscopic vision.Fig. 6 right-of-center in political views illustrates the beholder and moves right after the crosstalk zone, makes positive vision area move through Movable grid thereupon, can guarantee that the beholder produces correct stereoscopic vision.Continue to move right the beholder, when getting into, can switch left and right image against vision area.So, the beholder all can produce correct stereoscopic vision on almost any position of laterally moving, and this effect is shown in left figure below among Fig. 6.Through these behaves, successfully increased the scope of watching in the horizontal.
Through adjustment to display unit or light-splitting device; Except can realizing watching subarea moving in the horizontal; Also can realize the variation of viewing ratio, arrange on cycle, the light-splitting device spectrophotometric unit width (like the pitch of lens unit) etc. like the adjustment display unit.
But, the tracking technique of stereo display at present is primarily aimed at view single (site) person, and on the large scale stereoscopic display device, during the application tracking technology, just must consider the demand that many people watch.And under the scene of the bore hole stereo display that many people are followed the tracks of; Just can not as above-mentioned single tracking, only consider a beholder's needs; And need take all factors into consideration a plurality of beholders' the needs of watching, make beholder as much as possible enjoy the stereo display effect.But, also do not have corresponding solution at present.

Embodiment two
Present embodiment carries out the adjustment of display parameters according to the geometric distance of the beholder position projection centre corresponding with the valuation to be evaluated of display parameters.
Present embodiment tracking mode bore hole stereo display control method is as shown in Figure 8, comprises the adjustment process of display parameters, and this process comprises:
Step 110, the valuation to be evaluated of taking out the display parameters of setting;
The display parameters of setting are meant and are used to realize that many people follow the tracks of the display parameters of the target viewing area adjustment under the scene.Present embodiment comprises display unit arrangement cycle and display unit deviant.But in other embodiment, can be that display unit is arranged one or more in cycle, display unit deviant, spectrophotometric unit deviant and the spectrophotometric unit width.When the adjustable display parameters of setting are one or have a plurality of but when adjusting respectively, be once to take out a valuation to be evaluated,, then once take out one group of valuation to be evaluated if any a plurality of display parameters and adjustment simultaneously.
Present embodiment is once one group of valuation to be evaluated of taking out to be assessed, and comprises the valuation to be evaluated in a display unit arrangement cycle and the valuation to be evaluated of a corresponding display unit deviant.But, then once a valuation to be evaluated of taking out is assessed in other embodiments, if once a parameter is advanced adjustment.
Display unit is arranged the valuation to be evaluated in cycle and can be taken out in such a way: go out the viewing distance scope that maximum viewing distance and minimum viewing distance the beholder limit according to said beholder's position calculation; Then calculate the corresponding display unit of said viewing distance scope and arrange the span in cycle; In the span in said display unit arrangement cycle, take out the valuation to be evaluated that display unit is arranged the cycle then.Because being a display unit, the size of the span of display unit deviant arranges the cycle; Therefore after the valuation to be evaluated in display unit arrangement cycle is confirmed; Display unit is arranged the span of this valuation to be evaluated in cycle as the display unit deviant of correspondence, can take out the valuation to be evaluated of a plurality of display unit deviants.Each display unit is arranged the valuation to be evaluated in cycle and can be assessed together as one group of valuation to be evaluated corresponding to the valuation to be evaluated of a plurality of display unit deviants.
The value mode of spectrophotometric unit width is similar with the value mode that display unit is arranged the cycle, and the value mode of the display unit deviant that the value mode of the spectrophotometric unit deviant that the spectrophotometric unit width is corresponding and display unit arrangement cycle are corresponding is similar.Repeat no more at this.
Though the value mode of present embodiment as above; But the present invention is not limited to this; As can arrange the cycle and/or the spectrophotometric unit width is provided with a span in advance and obtains the respective display unit deviant and/or the span of spectrophotometric unit deviant, and do not consider beholder's position for display unit yet.Perhaps, can be earlier calculate an average according to beholder's viewing distance after, be that the setting range at center is the span that display unit is arranged cycle and/or spectrophotometric unit width with this average again, or the like.
During concrete value, can, display unit take out valuation to be evaluated respectively in arranging the span of span, respective display unit deviant in cycle according to the step-length of setting.Can get all values according to a step-length, also can use a plurality of step-lengths, get valuation to be evaluated by big step-length earlier,, take out valuation to be evaluated by smaller step size again as not having suitable value after the valuation assessment to be evaluated of taking out.And on the order of value and assessment; Can once take out all valuation to be evaluated and then assessments; (display parameters take out one also can to take out one or one group of valuation to be evaluated; Take out a plurality of when a plurality of display parameters are arranged simultaneously) back just to this maybe the valuation to be evaluated of this group assess, and then get the next one or one group of valuation to be evaluated is assessed.The concrete processing the present invention does not here limit.
When having only a beholder's position, can use other control method, the present invention is not discussed.
As shown in Figure 9, this step can be divided into following steps again:
The corresponding relation of the position of projection centre and the valuation to be evaluated of display parameters can calculate in real time, also can preserve in advance.
Two quadrangles shown in figure 10 are positioned on the XZ plane, and p1 and p2 represent first beholder and second beholder's position respectively, its immediate projection centre and p1; P2 is on same XZ plane, and O1O2 representes respectively and p1, immediate two projection centres of p2; L1 and L2 represent summit and the projection centre O1 on the target viewing area vertically respectively; The line of O2, L3 are process O1O2 and the straight line that is parallel to display screen, and L3 is a viewing ratio to the distance of display screen.P1b1, p2b2 are the straight lines that is parallel to L3.P1a1 is the vertical line of p1 to L3, and P2a2 is the vertical line of p2 to L3.
Position p1 with first beholder is an example; In the literary composition; The length of the line segment O1p1 on this plane is defined as the point-to-point distance of this beholder projection centre O1 immediate with it; The length of line segment p1b1 is defined as the lateral separation of this beholder to projection centre O1, the length of line segment O1b1 or the length of p1a1 are defined as the fore-and-aft distance of this beholder to projection centre O1.
Above-mentioned weighted average can be to average, but also can compose different weights to the beholder of diverse location, and weights are as can rule of thumb being provided with or confirming through modes such as emulation, debugging.
In the present embodiment, what when calculating, adopt is the point-to-point distance of beholder's projection centre immediate with it.But also can adopt in other embodiments, the lateral separation or the fore-and-aft distance of beholder's projection centre immediate with it.
In some change examples of present embodiment; Position and the minimum of the fore-and-aft distance between the immediate separately projection centre that can also said beholder be alternative condition; Select the value of first display parameters; Be alternative condition with the lateral separation minimum between said beholder's position and the immediate separately projection centre again, select the value of second display parameters; Perhaps; Lateral separation minimum with between said beholder's position and the immediate separately projection centre is an alternative condition; Select the value of second display parameters; Be alternative condition with the fore-and-aft distance minimum between said beholder's position and the immediate separately projection centre again, select the value of first display parameters.
Step 130 is carried out the display parameters adjustment according to the desired value of said display parameters adjustment.
Because the beholder more near projection centre, just might produce stereoscopic vision more.Therefore; Present embodiment with the geometric distance sum between each beholder's position and the immediate separately projection centre as evaluation function; With the distance that obtains with or the weighted average minimum of distance be that alternative condition is confirmed the desired value that display parameters are adjusted, to obtain more excellent whole viewing effect.
Though being the valuation to be evaluated of once taking out two parameters, the foregoing description assesses simultaneously; But; In another embodiment, also can take out one of them earlier, arrange the valuation to be evaluated in cycle (like the spectrophotometric unit width) like display unit and assess; The method that adopts during assessment as above, just this moment, service range in computing should adopt the fore-and-aft distance of above-mentioned definition.Select the desired value of display unit arrangement cycle adjustment according to assessment after; Assess according to the valuation to be evaluated of the desired value of display unit arrangement cycle adjustment being taken out display unit deviant (or spectrophotometric unit deviant) again; The lateral separation of above-mentioned definition should be adopted during computing, just adjustment can be accomplished select the value of display unit deviant according to assessment after.
In addition, can increase some alternative conditions, obtain some and become example present embodiment.
For example; In step 1202; To or one group of valuation to be evaluated of display parameters, except the position and the geometric distance sum between the immediate separately projection centre that calculate all beholders, can also judge simultaneously whether all beholders are not in contrary vision area; If the beholder is arranged not in contrary vision area, then abandons this or one group of assessed value.Certainly this judgement also can be carried out or carry out earlier after calculate this geometric distance sum of all beholders.So, be equivalent to alternative condition is become with minimum and all beholders apart from sum between each beholder's position and the immediate separately projection centre not in contrary vision area.This is become example changes a little; The beholder is being arranged not in contrary vision area; Not to abandon this or one group of assessed value; But note each or one group of assessed value corresponding not in beholder's number of contrary vision area, the weighted average of said geometric distance sum or said geometric distance is minimum and be in that the beholder of contrary vision area is minimum to be alternative condition.
And for example; Become in the example at another; To each or one group of assessed value,, confirm to be positioned at the beholder's of the target viewing area that this maybe should group assessed value correspondence number according to the position of its corresponding target viewing area; Is alternative condition in when assessment so that geometric distance sum or the weighted average minimum of said geometric distance of maximum beholders between target viewing area and each beholder's position and immediate separately projection centre to be arranged, and selects the desired value that display parameters are adjusted.
