Detailed description of the invention
With embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, the present invention's includes with lower component towards 3 D stereoscopic image display system:
Stereoscopic image display unit: for receiving the 3 D stereoscopic image and three of three-dimensional user interface unit transmission
Dimension graphical interface of user；
Depth image sensing unit: be used for obtaining and sensing 3 D stereoscopic image display unit place environment, bag
Include user in interior deep image information；
Depth image processing unit: the visual range internal field depth of field obtained for analysis depth image sensing unit
Degree information, and identify the user object and whole body obtained by limb action recognition unit or part of limb motion；
Limb action recognition unit: be used for following the tracks of and identifying user action, and provide use for three-dimensional user interface unit
Family input controls interface；
Three-dimensional user interface unit: for sending graphical interfaces to stereoscopic image display unit, with 3 D stereo
The form of image is by display unit, and after receiving the user action of limb action recognition unit, moves user
Make to feed back on stereoscopic image display unit；
Three-dimensional position indicator unit: be used for receiving scene depth letter in depth image processing unit visual range
Identify active user's particular location at three-dimensional user interface after breath, and user's control action is made feedback.
Described depth image sensing unit connects depth image processing unit, and depth image processing unit connects limb
Body action recognition unit, described limb action recognition unit connects three-dimensional user interface unit, three dimensional user circle
Face unit connects stereoscopic image display unit and three-dimensional position indicator unit respectively.
Three-dimensional user interface unit of the present invention with the Windows operating system of Microsoft as reference, three dimensional user circle
Face unit is patterned, can include the interface elements such as window, icon, file, desktop, towards
Under 3 D stereoscopic image display system environment all of interface element all have depth attribute, i.e. interface object from
Open the distance of physical display screen it can be understood as a three-dimensional desktop in three dimensions.User can be led to
Crossing gesture motion to rotate, scale this three-dimensional desktop, all of window is the most vertically suspended in such a solid
In space, and any two is opened the depth difference between window and is maintained at more than the threshold range of setting, user
Can be captured by gesture motion, move, pull window interested and as focus window etc., this stands
The spatial dimension of body desktop keeps consistent with user's gesture motion effective range, such as extended when user's one hand
During relative user self the far-end upper right corner of effective range, three-dimensional position indicator also should move to this
The three-dimensional desktop far-end upper right corner, similar, when user's one hand is reduced to the relative user self of effective range
During the near-end lower left corner, three-dimensional position indicator also should move to this solid desktop near-end lower left corner.
The three-dimensional position indicator unit of the present invention can be a 3 D stereo in three dimensional user graphical interfaces
Little hand state, and corresponding metamorphosis, such as user can be made according to the gesture motion that user is different and doing
During propelling movement action, little hands is the five fingers expanded configuration, and user's little hands when doing drag motions is seized condition etc. of clenching fist,
User single-handed exercise be display one pinkie show device, when user does double-handed exercise again, be shown as two little
Hands indicator etc..Three-dimensional position indicator physical location in three dimensional user graphical interfaces is by user's hand phase
Displacement is determined, and direction and the speed of the moving direction of indicator and speed and user's hand motion keep one
Cause.
The present invention under the effect of depth image sensing unit, this system can obtain the limb action of user
Information, as a example by gesture motion, gesture motion effective range refers to one in physical display device screen and use
A specific region between the physical location of family, only after user's hand enters this region, system just can be right
User's gesture motion is identified, outside user's hand is positioned at this effective coverage, then and the gesture motion of user
Can be ignored by system, the locus scope of the gesture motion effective range application three-dimensional user interface of user is protected
Holding consistent, such user operation before 3 D stereo affects display device just can reach the people immersed completely
Machine interaction effect.
As in figure 2 it is shown, the present invention's uses following steps to realize towards 3 D stereoscopic image display system: one,
