Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the present invention is described in further detail.
Providing a kind of panoramic screen in one embodiment of the present of invention, described panoramic screen is around all or part of side forming handstand round platform.
This panoramic screen arc-shaped transition, thus on panoramic screen, image everywhere is and seamlessly transits, and does not haves sharp-pointed sense, picture is soft, and spectators' perception degree is high.
Additionally providing a kind of full-view screen system in one embodiment of the present of invention, comprising: above-mentioned panoramic screen and more than one scialyscope, described scialyscope is positioned at the top of described panoramic screen.
By the screen faced upward and light path, spectators distance can observe closer to the local of screen, are in other words exactly under equal size, can accommodate more attendance.
One embodiment of the invention additionally provides the operational approach of above-mentioned full-view screen system, including:
A. panoramic screen is erect and place, constitute handstand round platform；
B. scialyscope is placed in the top of described panoramic screen.
It follows that the present invention describes this panoramic screen in detail by a specific embodiment,
Embodiment one, such as Fig. 1, shown: panoramic screen, in order to prevent image projection to constitute sharp-pointed transition effect to this screen, this panoramic screen is around forming handstand round platform surface, and wherein, the surface of handstand round platform includes: round platform bus rotates 120 °-330 ° parts formed.It addition, for the integrity keeping image, avoid the picture effect caused because of the splicing line of screen, improve perception as far as possible, this panoramic screen uses integral seamless structure.In conjunction with actual visual effect, including spectators' point of observation, the angle of inclination of the head of spectators, the angular field of view of spectators, the tapering of described round platform is 5 °-12 °, being preferably 5 °, height is 1800-5000 millimeter, preferably 2800 millimeters, bottom surface radius is 2500-5000 millimeter, being preferably 3050 millimeters, end face radius is 2800-5600 millimeter, preferably 3300 millimeters.Facilitate panoramic screen can receive all of projection, and project and can be uniformly distributed, and then improve projectable's effect of panoramic screen.
Embodiment two: unlike embodiment one, this panoramic screen is around the whole sides forming handstand round platform.
It follows that the present invention describes full-view screen system in detail by a specific embodiment, such as Fig. 2, shown:
A kind of full-view screen system, is made up of above-mentioned panoramic screen and multiple scialyscope 3, in order to save the floor space of whole full-view screen system, scialyscope 3 is placed on the top of panoramic screen.By the screen faced upward and light path, spectators distance can observe closer to the local of screen, are in other words exactly under equal size, can accommodate more attendance.
Have employed above-mentioned panoramic screen in this full-view screen system, so that projected the image smoothing transition on panoramic screen by scialyscope 3, without breakpoint, perception is effective.
Being adjusted the riding position of panoramic screen for convenience, the tapering of regulation panoramic screen, this full-view screen system needs to be equipped with mechanical adjusting structure, to regulate panoramic screen in level to, vertical inclination angle, preferably makes panoramic screen keep smooth vertical and horizontal.In certain embodiments, this mechanical adjusting structure generally uses bolt arrangement, such as Fig. 3, shown.By nut position on stud, panoramic screen is adjusted.
Any optical projection system all has image definition to adjust structure, the full-view screen system of the present invention designs for the structure of its uniqueness, the mode used is: full-view screen system is furnished with laser dot-matrix assembly, this laser dot-matrix assembly can project to panoramic screen to form laser datum grid, scialyscope 3 is then provided with datum mark matrix component, this datum mark matrix component can project to panoramic screen to form datum mark grid, in definition adjusts, carry out datum mark grid with laser datum grid overlapping adjustment and then completing geometric correction.
This full-view screen system further comprises scialyscope 3, in order to enable the projection of scialyscope 3 to cover whole panoramic screen, so in order to improve the uniformity that scialyscope 3 projects on panoramic screen, need multiple scialyscope 3, scialyscope 3 is encircled a city circular arc, curved is uniformly distributed, and selects 4 in certain embodiments, laying respectively at the top of panoramic screen, other embodiments can also select 5,6 or more.Scialyscope 3 projects image onto on panoramic screen from top to bottom, the panoramic screen of circular arc transition, promotes that the picture of projection is relatively releived, image presents soft sense, it is possible to increase the perception of spectators.
The setting of the tapering of panoramic screen and the highly desirable satisfied lower limb 1 that can project to panoramic screen with scialyscope 3 of scialyscope 3, and, the spectators that the light path of each scialyscope 3 can not be in viewpoint stop.Therefore, arranging of scialyscope 3 can perform according to this principle.
Described scialyscope is positioned at above described panoramic screen at 500-1500 height.
Below, correspondence said structure of the present invention provides a more specifically full-view screen system, such as Fig. 2, shown: a height of 2800 millimeters of full-view screen system；The radius (i.e. top radius) of the top edge 2 of panoramic screen is 3300 millimeters；The radius (and bottom radius) of lower limb 1 is 3050 millimeters, and the radian of top edge 2 is 120 °-330 ° and (includes 120 °, 140 °, 160 °, 200 °, 230 °, 260 °, 300 °, 330 ° or other value.), described scialyscope 3 is positioned at more than the height at panoramic screen top edge 2 place 700 millimeters.At 1.75 meters, the top in the center of circle that the eyespot of full-view screen system is located at the circle at described lower limb 1 place.
It should be noted that, as long as the projecting light path meeting throwing camera can arrive top edge 2 and lower limb 1, and, the spectators that the projecting light path of scialyscope 3 is not at viewpoint are stopped, tapering, the size of radius at upper and lower edge will not be adhered rigidly to and each numerical value in upper embodiment.
In corresponding the various embodiments described above, the operational approach of full-view screen system is:
Panoramic screen is erect placement by 101., constitutes handstand round platform；
102. regulation mechanical adjusting structure, make panoramic screen keep smooth vertical and horizontal；
103. tops that scialyscope is placed in described panoramic screen；
104. form laser datum grid by laser dot-matrix assembly to the projection of described panoramic screen；The datum mark matrix component of operation scialyscope, forms datum mark grid to the projection of described panoramic screen；Overlap to carry out geometric correction with described laser datum grid by adjusting described datum mark grid.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
