Abstract
The invention discloses a demonstrator for handshake with oneself based on 3D technology, and belongs to the technical field of exhibition and display. The demonstrator is composed of a 3D camera, a 3D display, a pair of 3D glasses and a demonstrator casing, a 3D picture of a hand, which is stretched out in front of the demonstrator, can be displayed on the display, and when the 3D glasses are used for watching, the effect is the same as that handshake with a real hand. The problem of incorrect handshake direction when a concave mirror is used to prepare the demonstrator is solved. The demonstrator is used in public places as a science and technology museum, and serves as an interaction display for entertainment as well as learning science and technology knowledge.
Description
Technical field
The present invention relates to a kind of " shaking hands with oneself " apparatus for demonstrating based on 3D technology, be the optics sci-tech exhibit put on display for science and technology center, belong to display and demonstration technical field.
Background technology
Exhibition item of " shaking hands with oneself " is traditional showpiece that most of science and technology center all possesses, the interesting effect that can present spectators oneself He oneself shake hands.Showpiece utilizes the optical principle of concave mirror imaging, when hand is placed on the center of curvature of concave mirror by spectators, reflection image be inverted at center of curvature place, etc. large real image, the effect of hand together with oneself is held really in mirror can be observed.
The actual bandwagon effect of showpiece of " shaking hands with oneself " is more weak, and the impression of shaking hands is not obvious.Main disadvantages has be the large images such as spectators not easily search out the center of curvature, inversion not easily occur at two: one; Two is that to determine its imaging be that all directions are all reversed for the principle of concave mirror imaging,
as Fig. 1shown in, hand 2 and the real hand 3 of imaging inside concave mirror 1 present inverted relation, in fact do not hold.
Summary of the invention
Goal of the invention: " shaking hands with oneself " apparatus for demonstrating based on 3D technology provided by the invention, takes with 3D, show, is viewed as ultimate principle
novelshowpiece, perfect realization " shaking hands with oneself ", makes spectators understand 3D imaging and display technique simultaneously.
Technical scheme: a kind of " shaking hands with oneself " apparatus for demonstrating based on 3D technology of the present invention,
as Fig. 2shown in
, in figure1 be 3D video camera, 2 is 3D displays, and 3 is video transmission lines, and 4 is 3D glasses, and 5 is the hands be taken, and 6 is space images of the hand presented in display.
3D video camera 1 is placed on the top of 3D display 2, display outrunner hand 5 can be photographed, by video transmission line 3, the vision signal of video camera 1 is connected on 3D display 2, demonstrate the space image 6 of the hand contrary with staff 5, stereoeffect can be seen by 3D glasses 4, just as stretching a hand in display, two hands just can be held one and play.
Beneficial effect: when hand reaches before display by spectators, just demonstrate the hand that a grade opposed with spectators' hand left and right is large, the visual effect of the hand of oneself together with virtual holding can be seen with 3D glasses, there is stronger interest, intellectual and interactive, more existing " shaking hands with oneself " showpiece improves bandwagon effect, describe 3D stereoscopic shooting and display technique to spectators simultaneously, meet the demand of science and technology center to optical technology showpiece.
Accompanying drawing explanation
fig. 1for principle and the effect signal of existing " shaking hands with oneself " showpiece
figure.Wherein 1 is concave mirror, and 2 is pictures that hand becomes, and 3 is real staff.
fig. 2for based on " shaking hands with the oneself " apparatus for demonstrating of 3D technology and effect signal
figure.Wherein 1 is 3D video camera, and 2 is 3D displays, and 3 is video transmission lines, and 4 is 3D glasses, and 5 is the actual human hand be taken, the space image of the hand 6 to present in display, seen by 3D glasses.
fig. 3it is a kind of signal of embodiment
figure.Wherein 1 is the shell of whole exhibiting device, and 2 is 3D camera lens holes, and 3 is 3D displays, and 4 is the interaction portion can seen in device outside, and 5 is 3D glasses, and 6 is 3D eyeglass holders.
Embodiment
Below in conjunction with
accompanying drawingthe present invention is described in detail with specific embodiment.
Embodiment citing one:
fig. 2shown principle
figurenamely can be used as embodiment, invention effect can be reached.
in figure:
1 is 3D video camera, and technical parameter, without particular/special requirement, adopts commercially available finished product, the SD30 of such as AEE;
2 is 3D displays, and current commercially available most of display, all with 3D function, selects suitable dimension according to demand;
3 is video transmission lines, in theory any one can, such as HDMI wire, AV concentric cable etc.;
4 is 3D glasses, and the mode forming 3D with video camera is coincide, and adopts commercially available polarization type 3D glasses herein.
When 3D video camera 1 photographs 3D display 2 outrunner's hand 5, signal is passed to 3D display 2 by video transmission line 3, the space image 6 of hand just shows on the screen of 3D display 2, when watching with 3D glasses 4, just can see space image 6 in one's hands, see and the effect of shaking hands that real hand 5 is formed simultaneously.
During concrete enforcement, first 3D display 2 is fixed, 3D video camera 1 is fixed on above display 2, connect video camera 1 and display 2 with video transmission line 3.Energizing test, just can at 3D display 2 space image 6 in one's hands by 3D glasses 4, and the angle of inclination of adjustment 3D video camera 1 and focal length, make staff 5 and space image 6 form relation of perfectly shaking hands, and fix, whole device just completes.When spectators stretch out one's hand in front of the display, just the very vivid effect of shaking hands with oneself can be seen.
Embodiment citing two:
The showpiece of science and technology center is exquisite face shaping and bandwagon effect, if just principle device is showed, allows spectators see all structures, just loses thinking processes, feel flat and insipid, although also can reach interactive displaying object, effect will be far short of what is expected.Therefore general showpiece is all need packaging.
fig. 3it is the signal of another embodiment
figure, principle and process are completely same as the previously described embodiments, just design outward appearance and pack.
in figure1 is the cylindrical housing of whole exhibiting device, and can be made by various material and decorate, except 3D glasses 5 and eyeglass holder 6 are arranged on outside housing, miscellaneous equipment be all hidden in cylinder, does not allow spectators see, to increase mystique; 2 is 3D camera lens holes; 3 is 3D displays, only exposes the circular portion of an indicator screen; 4 is the interaction portion can seen in device outside.When spectators stretch out one's hand facing to this device time, just can see the effect of shaking hands with oneself in 3D glasses 5, more meet the custom requirement of people to such showpiece outward appearance.
