Description
Technical field
The present invention relates to a kind of projection imaging system, more particularly, to a kind of virtual reality projection imaging system.
Background technology
Virtual reality technology（Virtual Reality, abbreviation VR）It is the new and high technology occurred in recent years, by using meter
A series of means such as calculation machine, mode carry out virtual mould to even some things being also in the imagination of people of the things in reality
Intend, and pass through the modes such as vision, the sense of hearing even tactile, there is provided to user with sensory experience on the spot in person.Subsequent VR technologies
Increasingly mature and development, its application field also gradually widens.Up to the present, virtual technology is in teaching, process industry, building
Have been obtained for being widely applied with fields such as urban planning, show business, medical science, petroleum industries, and achieve it is good into
Just.
Virtual reality technology has feeling of immersion (Immersion), interactivity (Interactivity) and conception
(Imagination) three principal characters.Feeling of immersion, refer to that reality environment is supplied to one kind of user to experience virtual thing
The really degree of thing, this sense of reality include vision, the sense of hearing, tactile etc.；Interactivity, refer to user and virtual environment
Between certain interaction mechanism be present, user can be operated by certain mode to the things in virtual environment.User
Realize that it is exactly virtual reality projection imaging technology to immerse one of interactive mode with virtual reality (VR).
In a variety of virtual reality display systems that can bring live feeling of immersion often have equipment, virtual three-dimensional Projection Display system
Unite with its height telepresenc and height property of participation, participant is really realized that the information interchange with Virtual Space is conceived with reality,
As the virtual reality and vision simulation realization rate and mode generally used in the world at present, it is most widely used.
Feeding type virtual reality display system, more commonly used is the stereoprojection system based on stereo projection technology
System.The general principle of stereoscopic display is sought to manually to reappear parallax, will have horizontal parallax left-eye image and
Eye image is conveyed to the left eye and right eye of observer respectively so that observer can perceive three-dimensional depth, form third dimension.
In the Projection Display virtually shown, when the subpoint of projector equipment and the sight point location of user are apart from each other
When, the shape of projection will be deformed or distorted because of the change of view field and projection angle, and the projected picture that user observes will
It is deformed.In order to solve the above problems, 201610754119.7 patent of invention proposes a kind of virtual reality projection imaging
System, wherein projecting apparatus is arranged in the set distance range of 3D glasses, the projecting direction of projecting apparatus and the vision of 3D glasses

Side extends to right eye 30 and forms plane 107 and the crossover location of projecting subassembly rightmost side perspective plane 108 with the projector space leftmost side.
So as to which, the second shielding plate 50 is not in the case where blocking the display light of display space 200, can block projection path 101 and
Scattering light on 104.
First shielding plate 40 and the second shielding plate 50 can use the conventional light-locking material in this area, by welding, glue
The modes such as patch are arranged on 3D glasses.
By the setting of above-described embodiment, the scattering light in the projected path of projecting subassembly can be made, especially distance is used
Eyes nearer scattering light in family is shielded, and light is scattered in projected path for user's virtual reality viewing effect so as to reduce
Influence.
Second embodiment
The virtual reality projection imaging system of first embodiment of the invention, including 3D glasses, projecting subassembly, motion recognition system with
And control system.Wherein 3D glasses are arranged on eyes of user, and the light for making to reach human eye by 3D glasses forms 3-D effect.
The 3D glasses of polarization type 3D glasses or 3 D active eyeglasses as virtual reality projection imaging system can be used.
Projecting subassembly, it is arranged at the point midway between two eyeglasses of 3D glasses, so that projecting subassembly distance is seen
Point location be less than setting 50cm setting distance range, for by virtual reality projection imaging in display space.Pass through throwing
The distance of shadow component and 3D glasses is set, and is made the projecting direction of projecting apparatus consistent with the visual direction of 3D glasses, is obtained anti-twist
Projection imaging system, so as to which projected picture will not be deformed or distort.
Motion recognition system, the spatial position change of the user of its real-time capture 3D glasses, the spatial position change include
Head and the change of body space position, the spatial position change of the user of seizure is sent to control system by transmitting element
System.
Control system, it refreshes corresponding virtual reality scenario video content according to the spatial position change information of user,
It is logical that virtual reality scenario video content after refreshing is transferred to projecting subassembly, the virtual reality scenario after the refreshing of projecting apparatus component
