A kind of computer graphic image display device is mainly used in the exhibition version, the show window that substitute in exhibition center and the museum, outdoor large advertisement column, propaganda board, large electronic display, and as the artistic carrier that designs of virtual environment.
Background technology
The exhibition version and the show window of present exhibition center, museum, exhibition, and outdoor large-scale advertisement hurdle and propaganda board all be to arrange with in kind, and can only use once, if show other content, must all remove, can not use repeatedly; The matrix display that the dull and stereotyped electronic display of present outdoor large is to use light emitting diode and electroluminescent device etc. to form mostly, though can switch graph image at any time, but involve great expense, can not be big fully, and picture can only be the plane, can not form three-dimensional penetrating image.
Summary of the invention
Need arrange defectives such as material object, inconvenience perhaps involve great expense in changing in order to overcome existing exhibition and advertisement facility, the utility model provides a kind of image display system that is combined with computer projection equipment by transparent mask.Its purposes has two:
1 is material and inspirit culture exhibition place and outdoor exploitations such as exhibition center, museum, exhibition, and a kind of novel carrier is provided---the transparent mask of exhibition.What this transparent mask was mainly showed is not in kind own, but has a relief material picture (but can deposit material object equally) with computer or video camera can looking genuine of making, this image both can be a still frame, also can be moving frames such as the also luxuriant computer animation of figure, literary composition, sound, film, TV, put the object that mouse just can put on display according to spectators' needs moment replacing in order, and each object can use repeatedly thousands of times.The canopy of the heavens of venue such as exhibition center, museum, wall, dividing plate all can be inlayed with transparent mask unit by exhibition and be formed.This exhibition room and museum are general digital exhibition centers truly.Need not arrange original work and material object during exhibition, only the multi-media image copy of works or material object need be entered computer and be kept at data center again, just can access displaying at any time.Be the vehicles development history museum today, dirigible that is circling in the air on the canopy of the heavens each period and aircraft, the carriage that is running quickly on the wall each period, automobile and motorcycle, only wooden boat in each period of travelling on the dividing plate, sailing boat and volume steamer; Can be Olympic Games museum in thousand tomorrow, team member's the heroic bearing of parachuting of waving on the canopy of the heavens, and the big strong wind that shows the member of track and field sports unit on the wall is representing aquathlete's majestic appearance on the dividing plate; Be the oriental art exhibition morning, and can be the Western Culture fair afternoon ...
2 create a kind of solid and transparent virtual environment artistic carrier---the transparent mask of building formula in actual environment, the transparent mask of building formula is distortion and the expansion of exhibition with transparent mask, but more can be for " door and window " and buoyancy module of visitor's turnover, both can tower on the ground, also can swim on the water surface.Can be by virtual sculpture from projector to the transparent mask projection of building formula computer manufacture, Virtual Building, story animation, films and television programs, tridimensional advertisement, science popularization and moral promotional content or the like, the scene that can also show according to the needs real-time update in spectators and market.This scene is by computer-controlled, both can be static, also can be dynamic change; Both can be that today is existing, also can be historical or following; Both can be that nature exists, also can be that illusion is come out in our brains.This scene is a reality, is again illusory, gives that I have a dream and yet, not a dream, dim graceful U.S., and spectators go " visit " in the middle of can also being deep into the virtual image.To discuss abundant ruins is example, as long as we establish some transparent masks of building formula that have door opening around building ruins, the abundant former capital of merchant, by projector the image of the original building of computer simulation, project on the curtain wall of transparent mask (all should show the orthogonal projection of image on each face curtain wall), just can on ruins, reproduce all original style and features of the Yin Dynasty before more than 3300 year, can also reappear the public morals folk custom of merchant Yin Shehui " very impressive ", spectators can come among the virtual scene via door opening, experience and discuss the Yin Junchen common people's life then.Equally, we also can very economical, easily on the ruins in Yuanmingyuan Park, reproduce the brilliant and bustling of Yuanmingyuan Park, New York World Trade Organization mansion in the past on the ruins of New York World Trade Organization mansion, no matter on the spot in person the going of spectators recollected, go to visit and pounder on the past.
Technical solution adopted in the utility model:
We know.The velocity of propagation of light in optically denser medium be less than the velocity of propagation in optically thinner medium, therefore enters optically thinner medium from optically denser medium when light, perhaps when optically thinner medium enters optically denser medium, all refraction effect will take place.Use this principle, we can be nature or artificial image, with light be carrier by air borne to than on the big transparency medium of atmospheric density, just can form the virtual image of image.Again because this optically denser medium is the transparent body, the virtual image that is generated is not only like dreams, glittering and translucent, and be not reflected or the light that absorbs can see through the eye that this optically denser medium propagate into people, make the people who stands in transparent optically denser medium behind also can see the virtual image.
The utility model mainly is made of projector, reflective mirror and transparent mask.Its principle of work is as follows: under the control of computer data center, to reflective mirror, reflective mirror secondary reflects to the image display area of transparent mask to the virtual image that projector's projection comes the image projection of computing machine and video camera making in projector.Secondary reflection makes the light path of projection prolong one times, has obtained abundant big display image in the limited projector distance of transparent mask.
This use is novel with general optical projection system difference, and general optical projection system observer is in the same side of image-carrier with projector, and the utility model observer is in the front and back sides of image-carrier respectively with projector; Simultaneously, image throws through secondary from the emissive source to the carrier, so we are called it " back projection ".
Main body of the present utility model is transparent mask.Transparent mask can be divided into exhibition with transparent mask and two kinds of embodiments of the transparent mask of building formula.They all are much the same on structure and usage, have common substantive technology, and just latter's volume is bigger, many some annexes.Though computing machine and projector are the source of image in back projection system; be the basic of the design, but they are very ripe prior aries, the utility model just is applied; so the technical characterictic that does not belong to the utility model protection is not explanation in detail.
For make and arrange exhibits on convenience, exhibition should be made the structure of blocking with transparent mask, again by transparent mask unit connection or be set into wall, the canopy of the heavens and the dividing plate of exhibition room and museum.
