DETAILED DESCRIPTION OF EMBODIMENTS
The present invention provides an omni-directional dynamic tracking viewing system, in order to make the purpose, technical solution and the advantages of the present invention clearer and more explicit, further detailed descriptions of the present invention are stated here, referencing to the attached drawings and some embodiments of the present invention. It should be understood that the detailed embodiments of the invention described here are used to explain the present invention only, instead of limiting the present invention.
Referencing to FIG. 1, which illustrates a schematic diagram on a preferred embodiment of the omni-directional dynamic tracking viewing system after viewers have boarded the viewing platform, as provided in the present invention, as shown in the figure, it comprises a spherical silver screen 600, a bracket 300 arranged in the spherical silver screen 600, a viewing platform 100 connected movably to the upper end of the bracket 300, and a projection device 400 arranged fixably onto the viewing platform 100 (as shown in FIGS. 2-6 combining together), a plurality of rows of viewing seats 200 are disposed on the viewing platform 100; seat drive apparatuses are disposed on the viewing seats 200, used for driving the forward tilt or backward recline thereof; and a platform drive apparatus is disposed on the viewing platform 100, used for driving the rotation of same on the X axis, Y axis, and Z axis.
As shown in FIGS. 2-6, the viewing platform 100, as provided in the present invention, may rotate across the upper end of the bracket 300 in directions around the X axis, Y axis, and Z axis, thus make viewers be able to watch in all directions. The said viewing seats 200 may be arranged into 5 rows, or other numbers of rows according to any real requirements. However, when it is arranged into 5 rows, the first, fourth and fifth rows comprise 17 viewing seats each, while the second and the third rows comprise 6 viewing seats on each of left and right sides, and the projection device 400 is arranged at the center of the third row, which is also the center of the spherical silver screen 600.
In order to arrange all viewers on the viewing platform 100 locating at the center of the spherical silver screen 600, thus bringing all viewers a larger viewing range, the upper end of the said bracket 300 locates at the spherical center of the spherical silver screen 600
The seat drive apparatus as provided in the present invention may be an electric power driven apparatus, a hydraulic driven apparatus or a pneumatic driven apparatus.
Additionally, as shown in FIG. 1, it further includes a telescope apparatus 500 to commute viewers to and from the viewing platform 100, with the help of the said telescope apparatus 500, viewers may be sent to the viewing platform 100.
Wherein, the viewing platform may be designed as 15 meters high, and 10 meters wide, gaps between the viewing seats arranged in two sides of the second row and the third row are 2 meters, and gaps between seats in each row may be arranged into 0.5 meters or 1 meter. Wherein, the said seat drive apparatus further connects to a synchronization mechanism, applied to control the seat drive apparatus make synchronization actions, following the actions played in the video pictures from the projection device 400, for example, when the current video pictures shake from left to right, or shake from upper down, the synchronization mechanism will control the said seat drive apparatus swing from left to right, or swing from upper down, therefore, make the viewing seats generate the same actions, while the amplitude, frequency and more are synchronizing with the video pictures.
