Description
Technical field
The present invention relates to holographic real-time virtual reality system, the scenic spot holographic real-time for being based especially on cloud is virtual
Reality system is mainly used for the tourism of real-time virtual three-dimensional.
Background technique
Growth momentum is rapid in recent years for Tourism in China (only referring to that conventional physical is traveled here), but for consumers,
Selection conventional physical mode of tourism remains many limitations.
First is that being limited by itself economic condition, the tourist famous-city in numerous ideals is put because of oneself unbearable expense
It sets, especially external graceful sight spot.
Second is that can not undergo the sight spot admired to oneself by physical qualification (sick, injured, old).
Third is that time cost, the place wanted to go to is far away back and forth, itself not sufficient time and conventional physical trip
Swimming the ornamental time attribute in sight spot is node, it is difficult to realize the duration and comprehensive sexual experience to scenic spot.
Fourth is that bottleneck and pressure that tourism faces:
1. the problem of scenic spot bearing capacity, (especially after the event of outbeach, country paid much attention to scenic spot bearing capacity, and scenic spot cannot
Fully meet reception of visitor task)；
2. the problem of dull and rush season is unevenly distributed (global problem, the busy season is overstaffed, and dull season, you can catch sparrows on the doorstep, how peak clipping
It is valley-fill).
To solve the above-mentioned problems, it currently, having developed a kind of idea of real-time virtual three-dimensional tourism, is meant that, it will
One actual physics scenic spot is transported to another space by virtual reality technology, makes original scenic spot in another space like " sea market
Clam building or rainbow " virtual form is reproduced, for tourist in virtual scenic spot in real time in air in a manner of hologram three-dimensional imaging
Visit.
Virtual three dimensional travel scenic spot, have huge economic value and social value, by will on the spot physics landscape different
3D hologram tool in ground is existing, protects with realizing the ecosystem indirectly and the landscape in long-range strange land is demonstrated；On the other hand, Yi Xiechong
The scene (such as meeting, performance, historic scenery) wanted and Main Part of Tourism personalization tourism expression, can also obtain because of the technology

(reference light) generates interference, records interference pattern, that is, hologram by CCD, and data are delivered cloud processing later.
Wherein, for scenic spot, since target object volume is larger, laser can not still cover whole object after expanding
Surface, therefore, laser are needed using large-numerical aperture camera system, but current holographic technique is difficult to realize.For
This, the above problem of the prior art is solved present invention employs the method for parallel multi beam parallel laser irradiation.
Preferably, in order to reduce cost and installation difficulty, the present invention passes through " panoramic scanning " using common CCD camera
Image capture method obtains the hologram of object, to reach above-mentioned purpose.
Further, since each of hologram pixel all contains all collected objects within the scope of diaphragm
Information, and individual hologram that above-mentioned " panoramic scanning " method generates does not have the information of whole object, therefore, the present invention is logical
Cross using " after the hologram of multi collect difference scenery, then to multiple holograms carry out digit synthesis " method, with obtain compared with
Good effect.
In addition, since the light intensity of laser beam is not equally distributed on cross section, and this will lead to by expanding
Laser beam afterwards and brings adverse effect when forming hologram in the uneven distribution of the light intensity on irradiated object surface,
In order to solve the technical problem, the method that the present invention uses are as follows: be the single-mode laser of Gaussian Profile using basic mode light beam, pass through
Diaphragm filters light beam of the relative light intensity less than 1/2, retains bright spot of view-field center, is improved later using the beam-expanding system with reinforcing function
The equalization of intensity of light beam.
Wherein, four sides of 3D model are respectively corresponded using projector or LED and projects to pyramidal four sides
To holographic film on, so that viewer is respectively obtained different 3D views from four observed directions using the reflection of light.It can also add
Enter touch screen effect, to realize better view experience.
In one embodiment of the present of invention, in order to reach better view effect, the difference with previous embodiment is,
Local device terminal reappears the image processing method at virtual scenic spot are as follows: using 2.5D pyramid puppet holographic technique in holographic pyramid
The middle picture for forming the fixed object to suspend, the animation (such as bird, worm) of some moving objects is gone out using White Light Digital line holographic projections,
To guarantee that there is preferable real-time, then it is subject to AR (Augmented Reality, abbreviation AR) technology augmented reality, so that whole
A scene obtains the naked eye visual effect of shock.
Preferably, being aided with other sense organs (including sense of hearing, tactile) stimulation of Beyond Vision again, increase effect on the spot in person
Fruit.
In an Application Example of the invention, long-range cloud can be added in the certain places in the U.S., scenic spot, Yellowstone
Holographic scenic spot virtual information captures node device, equipment by the information captured by cloud be transferred to it is Chinese some be provided with
The holographic scenery in local these the special places that can reappear U.S. Yellowstone of holographic virtual reproduction area, such as wind,
Rain, temperature, air humidity, sound, sunlight, star, the moon, includes simultaneously real-time 3D holography virtual image at snow, and traveller is very
In addition the object such as flowers and plants, trees etc. that scenic spot can extremely be touched mixes terrain environment reconstruction technique, traveller is allowed to walk wherein
Even feel that oneself is just traveled in U.S. Yellowstone.
In conclusion the scenic spot holography virtual reality system of the invention based on cloud, using based on cloud
Holographic virtual display technology can have the famous scenic spot in strange land is true, holography is presented in face of traveller in real time huge
Big economic value and social value realizes ecosystem by that will have in strange land 3D hologram existing by physics landscape on the spot indirectly
The protection of system ground and the landscape demonstration in long-range strange land；On the other hand, some important scene (such as meeting, performance, historic sceneries
Deng) and Main Part of Tourism personalization tourism expression, it also can therefore be saved and three-dimensional demonstration and Interactive Experience in due course.Especially
It is that strange land virtual reality not only may be implemented in the present invention, also there is preferable real-time.
