Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
As shown in Figure 1, of the present inventionly comprise with lower member towards the 3 D stereoscopic image display system:
Stereopsis display unit: the 3 D stereoscopic image and the three-dimensional graphical interface of user that are used to receive the transmission of three-dimensional user interface unit;
Depth image sensing unit: be used to obtain and respond to 3 D stereoscopic image display unit place environment, comprise user's depth image information;
Depth image processing unit: be used for the interior scene depth information of visual range that analysis depth image sensing unit obtains, and discern user object and whole body or the part limb motion that obtains by the limb action recognition unit; Limb action recognition unit: be used for following the tracks of and the identification user action, and import control interface for the three-dimensional user interface unit provides the user;
Three-dimensional user interface unit: be used for sending graphical interfaces to the stereopsis display unit, with the form of 3 D stereoscopic image by display unit, and after receiving the user action of limb action recognition unit, user's action is fed back on the stereopsis display unit;
Three-dimensional position indicator unit: identify the particular location of active user after being used to receive the interior scene depth information of depth image processing unit visual range, and user's control action is made feedback at three-dimensional user interface.
Described depth image sensing unit connects the depth image processing unit, the depth image processing unit connects the limb action recognition unit, described limb action recognition unit connects the three-dimensional user interface unit, and the three-dimensional user interface unit connects stereopsis display unit and three-dimensional position indicator unit respectively.
Three-dimensional user interface of the present invention unit is reference with the Windows operating system of Microsoft, the three-dimensional user interface unit is patterned, can comprise interface elements such as window, icon, file, desktop, all has depth attribute at all interface elements under 3 D stereoscopic image display system environment, be the distance that interface object leaves the physics display screen, can be understood as a three-dimensional desktop in the three dimensions.The user can rotate by gesture motion, this three-dimensional desktop of convergent-divergent, all windows all vertically are suspended in such solid space, and any two depth difference of opening between the window remain on more than the preset threshold scope, the user can grasp by gesture motion, move, pull interested window and with it as focus window etc., the spatial dimension of this solid desktop and user's gesture motion effective range are consistent, for example as when user's one hand extends relative user self the far-end upper right corner of effective range, the three-dimensional position indicator also should move to this solid desktop far-end upper right corner, similarly, when user's one hand contracted relative user self the near-end lower left corner to effective range, the three-dimensional position indicator also should move to this solid desktop near-end lower left corner.
Three-dimensional position indicator unit of the present invention can be the little hand form of a 3 D stereo in the three-dimensional graphical interface of user, and can make corresponding metamorphosis according to the different gesture motion of user, such as user's little hand when doing the propelling movement action is the five fingers expanded configuration, user's little hand when doing drag motions is the seized condition etc. of clenching fist, the user is to show that a pinkie shows device in single-handed exercise, when the user does double-handed exercise again, be shown as two pinkies and show device etc.The physical location of three-dimensional position indicator in three-dimensional graphical interface of user is by user's hand relative displacement decision, and the direction and the speed of the moving direction of indicator and speed and user's hand motion are consistent.
Of the present invention under the effect of depth image sensing unit, this system can obtain user's limb action information, with the gesture motion is example, the gesture motion effective range is meant a specific region between physical display device screen and user's physical location, have only after user's hand enters this zone, system just can discern user's gesture motion, when user's hand is positioned at outside this effective coverage, then user's gesture motion can be ignored by system, the locus scope of user's gesture motion effective range applying three-dimensional user interface is consistent, and the operation of user before 3 D stereo influences display device just can reach the man-machine interaction effect of immersing fully like this.
As shown in Figure 2, of the present invention towards the realization of 3 D stereoscopic image display system employing following steps: one, the stereopsis display unit throws virtual three-dimensional graphical interface of user in entity space; Two, the depth image sensing unit obtains user place environment depth image information after the stereopsis display unit projects virtual three-dimensional graphical interface of user, and depth image information is sent to the depth image processing unit; Three, the depth image processing unit begins to discern user object and follows the tracks of user's hand motion after receiving depth image information, gives the limb action recognition unit with user's hand motion information feedback; Four, the limb action recognition unit judges that the user action gesture whether in the useful effect zone, is then to enter next step operation, otherwise returns previous step; Five, the limb action recognition unit is discerned user's gesture motion and is judged this action command; Six, the order after the limb action recognition unit will be discerned is sent to the three-dimensional user interface unit; Seven, the three-dimensional user interface unit is sent to the three-dimensional position indicator unit with information, upgrades three-dimensional position indicator post and state; Eight, the three-dimensional user interface unit is made respective feedback to the user action control command and is presented on the three-dimensional user interface unit.
Limb action recognition unit of the present invention can be discerned user's bimanualness, and its step is as follows: one, user's one hand enters the gesture motion effective coverage; Two, the three-dimensional position indicator unit upgrades three-dimensional little hand position and form; Three, the user moves in the effective coverage, and does to push when three-dimensional indicator is positioned at certain window ranges and move; Four, the limb action recognition unit identifies effective gesture motion for clicking order, and this window of three-dimensional user interface unit is set to the current focus window, and it is placed the front of current all windows; Five, the user stretches into the useful effect zone with the another hand; Six, the three-dimensional position indicator unit is updated to two three-dimensional little hand form, and position and both hands position are consistent; Seven, user's both hands are done in the current focus window ranges relatively away from action; Eight, the limb action recognition unit identifies this effective gesture motion for amplifying window command, and three-dimensional user interface is amplified to both hands relatively away from the distance proportion unanimity with this window.
