Sensor of type etc..Wherein recording device (keyboard, mouse have cotton gloves etc.) records the user action in true environment and leads to
It crosses sensor and is transmitted to control unit, the scene or object in control unit order display device generate corresponding reflection, observer
Interactive rear result is observed by display device.
Although said program realizes interactive display, but Shortcomings.Major part interaction technique is all confined to two dimension at present
Image, and it is all relatively simpler for the interaction effect of the more complicated three-dimensional environment of spatial relationship, and apparent interactive markup is very
It is beautiful that final image is affected in big degree.
The content of the invention
Problem and shortage existing in the prior art in view of the above, the present invention provide a kind of based on the virtual existing of 3D interactions
Real system.The system make observer by the data helmet obtain high definition 3-D view, and according to the observation viewing angle with
The gesture of observer changes scene angle and is shown with subjective situation so as to fulfill three-dimension interaction in real time.
In order to achieve the above objectives, the present invention uses following technical scheme：
A kind of virtual reality system based on 3D interactions, including the data helmet, ray trace camera group, multi-point touch screen
Curtain, rear-projection display screen curtain, back-projection instrument, front-end projectors, Master Control Unit, microcomputer group, HDMI wire, it is characterised in that：
(1) the ray trace camera group is positioned over room top, and distance is equal between adjacent camera；
(2) the rear-projection display screen curtain is put in perpendicular to ground above multi-point touch screen, the multi-point touch screen water
Placing flat, this two screen etc. is big, long side connects and orthogonal；
(3) the data helmet is worn on observer head, facing to rear-projection display screen curtain；
(4) the back-projection instrument face rear-projection display screen curtain is positioned over rear-projection display screen curtain back side suitable distance, described
Front-end projectors face multi-point touch screen is positioned at the suitable distance away from multi-point touch screen；
(5) the microcomputer group connects rear-projection display screen curtain and multi-point touch screen, the master control list by HDMI wire respectively
Member passes through radio contact with ray trace camera group.
Master Control Unit is made of modules such as 89C52 microcontrollers, CC2530F64 chips, power supplys.Ray trace camera group is adopted
Touch information is transmitted to Master Control Unit by the image wireless transmission collected to Master Control Unit, multi-point touch screen, and Master Control Unit receives
And it handles signal and is then wirelessly sent to microcomputer；It is corresponding to main body progress to the scene to prestore after microcomputer group wireless reception instruction to adjust
It is whole, while information is transmitted to projection unit and the data helmet by HDMI wire.
The present invention compared with prior art, has following obvious substantive distinguishing features and technological progress：
It is of the invention that the action of the number of people is recorded using ray trace camera compared with traditional interactive display system, so as to
Realizing that virtual scene is responded according to number of people direction transformation visual angle, spectators observe three-dimension virtual reality image by the data helmet,
It and can be with system interaction.
Present system connection is simple, and gained image resolution is high, interactivity is strong.
