For technology contents that the application is disclosed is more detailed and complete, can be with reference to accompanying drawing and following various specific embodiments of the present invention, in accompanying drawing, identical mark represents same or analogous assembly.Yet those of ordinary skill in the art should be appreciated that the embodiment that hereinafter provides limits the scope that the present invention is contained.In addition, accompanying drawing only is used for schematically being illustrated, and does not draw according to its life size.
As previously mentioned, full visual angle 3D shows the field in bore hole, can grasp by adopting eyeball tracking (Eye-Tracking) technology the position that user's eyeball moves, and makes unique user no matter stand in which position, all can see the 3D image of same effect.But the bore hole 3D that above-mentioned eyeball tracking technology only is applied in alone family is technical, and when watching for two or more users, prior art is comparatively ideal solution not yet.
The partial structurtes that Fig. 1 illustrates according to the naked-eye stereoscopic display of one embodiment of the present invention form schematic diagram.With reference to Fig. 1, naked-eye stereoscopic display of the present invention comprises that people's face detects module 100, a displacement calculating module 102, a view moves module 104 and an image is exported module 106.
Particularly, people's face detects position coordinates and the definite total number of users amount that module 100 is used for detecting each user in a plurality of users.Displacement is calculated module 102 and is connected with people's face detection module 100, and this displacement is calculated module 102 and is used for according to a plurality of users position coordinates separately, calculates and export the displacement of the interference range of naked-eye stereoscopic display.View moves module 104 and receives the displacement that calculates module 102 from displacement, and comes the view of mobile naked-eye stereoscopic display according to this displacement, makes the interference range corresponding one default view position of naked-eye stereoscopic display.At last, image output module 106 is exported a stereo-picture according to the view after movement, makes each use in a plurality of users can see correct stereo-picture per family.
In one embodiment, the maximum position coordinate interval between two users that module 102 also is used for calculating arbitrary neighborhood is calculated in displacement, and with the target location as interference range, the centre position at maximum position coordinate interval.for example, user User1, User2, when User3 and User4 watch the image of naked-eye stereoscopic display output in different positions, has position coordinates interval D 1 between adjacent user User1 and User2, has position coordinates interval D 2 between adjacent user User2 and User3, has position coordinates interval D 3 between adjacent user User3 and User4, and has position coordinates interval D 4 between adjacent user User4 and User1, module 102 chosen position coordinate interval D 1 are calculated in displacement, D2, maximum in D3 and D4, and with selected maximum position coordinate interval Max(D1, D2, D3, D4) centre position is as the optimal objective position of interference range, at this moment, each in user User1 to User4 is used per family apart from interference range farthest.Preferably, thus displacement calculate module 102 and obtain displacement according to the target location of interference range and the initial position view number separately of interference range.

maxEqual at 4 o'clock, displacement SV is 1.And for example, equal 5 and G as N
maxEqual at 2 o'clock, displacement SV is 3.Should be appreciated that for nine view coordinate systems, because the maximum coordinates of neighboring user is spaced apart 4.5, its maximum position coordinate interval G
maxAlso should be less than 4.5.In addition, in this coordinate system, interference range (Dead Zone) generally is set as the respective view coordinate less than 1.5 or greater than 7.5.
In one embodiment, the total number of users amount is set to be less than or equal to 5.Test factually data statistics and show, some to disturb the minimum resolution that zone position moves be 0.5 coordinate unit, and when number of users is 3, the success rate of testing 5832 times is 100%; When number of users was 4, the success rate of testing 104976 times was 99%; When number of users was 5, the success rate of testing 1889568 times was 94%.That is to say, when the number of users of watching naked-eye stereoscopic display remains on 5 or 5 when following, each is with seeing that the probability of correct 3D rendering is up to more than 90% per family.
In order to further illustrate above-mentioned nine view coordinate systems, the view the when naked-eye stereoscopic display that Fig. 2 illustrates Fig. 1 carries out position optimization to interference range.
With reference to Fig. 2, corresponding 3 users of naked-eye stereoscopic display, that is, and N1, N2 and N3.Wherein, user N1 and N2 are adjacent, have position coordinates interval Gap1 between both.User N2 and N3 are adjacent, have position coordinates interval Gap2 between both.User N3 and N1 are adjacent, have position coordinates interval (Gap31+Gap32) between both.Should be understood that, although the position coordinates interval of user N3 and N1 also can be labeled as (Gap2+Gap1), but, in view of user N2 just between interval (Gap2+Gap1) side, when in case interference range DeadZone is arranged in a certain position at interval (Gap2+Gap1), spacing distance between user N2 and interference range Dead Zone will be very near, easily causes user N2 to can't see correct stereo-picture.Hence one can see that, and interference range Dead Zone preferably is arranged at the centre position at maximum position coordinate interval (Gap31+Gap32), and for example, interval Gap31 equals interval Gap32.
Fig. 3 illustrates according to another embodiment of the present invention, and naked-eye stereoscopic display carries out the method flow schematic diagram of position optimization to its interference range.
With reference to Fig. 3, in interference range was carried out the method for position optimization, at first execution in step S11, detected the position coordinates of each user in a plurality of users and determine the total number of users amount.Then, in step S13, according to a plurality of users position coordinates separately, the position coordinates interval between two users of calculating arbitrary neighborhood.In step S15, coordinate interval, each position and an interval threshold are compared, when at least one position coordinates interval is not less than this interval threshold, according to a plurality of users position coordinates and maximum position coordinate interval separately, calculate and export the displacement of the interference range of naked-eye stereoscopic display.Then, in execution in step S17, move the view of naked-eye stereoscopic display according to the displacement that calculates, make interference range corresponding one default view position.At last, in step S19, export a stereo-picture according to the view after movement, make each use in a plurality of users can see correct stereo-picture per family.
In one embodiment, naked-eye stereoscopic display is corresponding to nine views (9-view) coordinate system, and the displacement of interference range calculates according to following relational expression:
SV=9-（N+1/2*G
max）
Wherein, SV represents the displacement of interference range, and N represents the user coordinates corresponding to maximum position coordinate interval; G
maxRepresent described maximum position coordinate interval.Further, the total number of users amount is set to be less than or equal to 5, and described interval threshold is 3.
In conjunction with Fig. 3 and Fig. 2, detect the position coordinates of each user in a plurality of users and determine total number of users amount (N1, N2 and N3).Then, according to a plurality of users position coordinates separately, calculate between two users of arbitrary neighborhood the position coordinates interval of (between N1 and N2, between N2 and N3 and between N3 and N2).With coordinate interval, each position Gap1, Gap2 and (Gap31+Gap32) and an interval threshold compare, when at least one position coordinates interval is not less than this interval threshold, according to a plurality of users position coordinates and maximum position coordinate interval separately, calculate and export the displacement of the interference range of naked-eye stereoscopic display.Then, move the view of naked-eye stereoscopic display according to the displacement that calculates, make interference range Dead Zone corresponding one default view position.At last, export a stereo-picture according to the view after movement, make each use in a plurality of users can see correct stereo-picture per family.
Fig. 4 A and Fig. 4 B illustrate respectively 4 users when stereo-picture is watched in different views positions, adopt the effect schematic diagram before and after the optimization method of Fig. 3.
In Fig. 4 A, corresponding 4 users of naked-eye stereoscopic display, wherein, user N1 is corresponding to view coordinate 1, and user N2 is corresponding to view coordinate 3, and user N3 is corresponding to view coordinate 5, and user N4 is corresponding to view coordinate 6, and interference range DZ1 is corresponding to view coordinate 9.By as can be known aforementioned, the view coordinate of interference range is commonly defined as less than 1.5 or greater than 7.5, and in this embodiment, user N1 can't see correct stereo-picture, and user N2, N3 and N4 all can see correct stereo-picture.
When adopting the optimization method of Fig. 3, at first, detect the position coordinates of each user in a plurality of users and determine the total number of users amount, in Fig. 4 A, user's position coordinates is followed successively by 1,3,5 and 6, and total number of users is 4; Then, according to a plurality of users position coordinates separately, position coordinates interval between two users of calculating arbitrary neighborhood, in Fig. 4 A, position coordinates between user N1 and N2 is spaced apart 2, position coordinates between user N2 and N3 is spaced apart 2, and the position coordinates between user N3 and N4 is spaced apart 1, and the position coordinates between user N4 and N1 is spaced apart 4; Then, with coordinate interval, each position and an interval threshold (for example, coordinate interval 3) compare, when at least one position coordinates interval is not less than this interval threshold, according to a plurality of users position coordinates and maximum position coordinate interval 4 separately, calculate and export the displacement 1 of the interference range of naked-eye stereoscopic display, computing formula is 9-(6+1/2*4), that is to say, the corresponding view coordinate of interference range should move to 8 from 9; At last, move the view of naked-eye stereoscopic display according to the displacement that calculates, make interference range corresponding preset view position (that is, the view coordinate 8).
Thus, in Fig. 4 B, although 4 users' position does not change, but user N1 is corresponding to view coordinate 2, and user N2 is corresponding to view coordinate 4, user N3 is corresponding to view coordinate 6, and user N4 is corresponding to view coordinate 7, and interference range DZ2 is still corresponding to view coordinate 9.Because the view coordinate of interference range is commonly defined as less than 1.5 or greater than 7.5, optimize when finishing, user N1, N2, N3 and N4 all can see correct stereo-picture.
Fig. 5 A illustrates 4 users in the second embodiment of stereo-picture is watched in different views positions, the effect schematic diagram when not adopting the optimization method of Fig. 3.Fig. 5 B illustrates 4 users in the second embodiment of stereo-picture is watched in different views positions, adopts the effect schematic diagram after the optimization method of Fig. 3.
In Fig. 5 A, user N1 is corresponding to view coordinate 2, and user N2 is corresponding to view coordinate 4, and user N3 is corresponding to view coordinate 6, and user N4 is corresponding to view coordinate 8.5, and interference range DZ1 is corresponding to view coordinate 9.Because the view coordinate of interference range is commonly defined as less than 1.5 or greater than 7.5, in this embodiment, user N4 can't see correct stereo-picture, and user N1, N2 and N3 all can see correct stereo-picture.
When adopting the optimization method of Fig. 3, at first, detect the position coordinates of each user in a plurality of users and determine the total number of users amount, in Fig. 5 A, user's position coordinates is followed successively by 2,4,6 and 8.5, and total number of users is 4; Then, according to a plurality of users position coordinates separately, position coordinates interval between two users of calculating arbitrary neighborhood, in Fig. 5 A, position coordinates between user N1 and N2 is spaced apart 2, position coordinates between user N2 and N3 is spaced apart 2, and the position coordinates between user N3 and N4 is spaced apart 2.5, and the position coordinates between user N4 and N1 is spaced apart 2.5; Then, with coordinate interval, each position and an interval threshold (for example, coordinate interval 3) compare, due to all position coordinateses intervals all less than this interval threshold 3, even this optimization method moves view and also can't make all users can see correct stereo-picture.
For example, in order to make new interference range corresponding to the centre position at the interval between the view coordinate of the view coordinate of user N3 and user N4, with counterclockwise mobile 1.75 coordinate unit of view, computing formula is 9-(6+1/2*2.5).As shown in Figure 4 B, user N1 is corresponding to view coordinate 3.75, and user N2 is corresponding to view coordinate 5.75, and user N3 is corresponding to view coordinate 7.75, and user N4 is corresponding to view coordinate 1.25, and interference range DZ2 is still corresponding to view coordinate 9.Because the view coordinate of interference range is commonly defined as less than 1.5 or greater than 7.5, optimize when finishing, user N1, N2 all can see correct stereo-picture, user N3 and N4 can't see correct stereo-picture.Hence one can see that, and the position coordinates interval between two users of arbitrary neighborhood must have at least a position coordinates interval to be not less than default interval threshold, could realize optimizing.
Adopt the optimization method of naked-eye stereoscopic display of the present invention and interference range thereof, detecting module by people's face detects the position coordinates of each user in a plurality of users and determines the total number of users amount, then utilize respectively displacement calculating module and view to move the displacement that module calculated and exported the interference range of naked-eye stereoscopic display, and come the view of mobile naked-eye stereoscopic display according to this displacement, make interference range corresponding one default view position, thereby allow each of a plurality of users with seeing correct stereo-picture per family.Than prior art, but a plurality of users' of the present invention's Auto-Sensing quantity and position, calculate best displacement and shift interference range, by the centre position of the interference range after shifting corresponding to the maximum position coordinate interval between two users of arbitrary neighborhood, make the user can see correct 3D stereopsis in the original place, and the interference range after the distance transfer farthest.
Above, describe the specific embodiment of the present invention with reference to the accompanying drawings.But those skilled in the art can understand, in the situation that without departing from the spirit and scope of the present invention, can also do various changes and replacement to the specific embodiment of the present invention.These changes and replacement all drop in claims limited range of the present invention.
