Abstract
The invention discloses a kind of Quasi-holographic three-dimensional display system, comprise display, wherein, described display is the cylindrical shape display that LED stereoscopic display unit is made, and described cylindrical shape display is the cylindrical shape display screen of Rotatable LED display screen or multiple LED display board composition.The present invention adopts LED three-dimensional display to make cylindrical shape, can adopt and show stereo-picture in various manners, also can use video acquisition software or animation Software for producing etc., according to the actual body display of the surrounding of object, realizes quasi-holographic display.
Description
Technical field
The present invention relates to a kind of tridimensional electronic large screen system, be specially a kind of Quasi-holographic three-dimensional display system.
Background technology
Holographic display needs to adopt high power laser and other equipment to form system, and system is huge and cost is high, but the brightness of final system is but very low, is difficult to realize popularization and application.
Summary of the invention
The object of this invention is to provide a kind of Quasi-holographic three-dimensional display system, overcome deficiency of the prior art, LED three-dimensional display is adopted to make cylindrical shape, can adopt and show stereo-picture in various manners, also video acquisition software or animation Software for producing etc. can be used, according to the actual body display of the surrounding of object, realize quasi-holographic display.
To achieve these goals, the present invention is by the following technical solutions:
A kind of Quasi-holographic three-dimensional display system, comprise display, wherein, described display is the cylindrical shape display that LED stereoscopic display unit is made, and described cylindrical shape display is the cylindrical shape display screen of Rotatable LED display screen or multiple LED display board composition.
As preferably, described multiple LED display board are the LED display board of multiple strip.
As preferably, described display is polarization-type, bore hole type, electronic shutter type or double-colored type display screen.
As preferably, described display can input 2 viewpoint 3D three-dimensional signals or 2 viewpoint animation data-signals.
As preferably, described display screen can show circumference stereo-picture.
As preferably, described display acquisition frame order is: the first data rows that the first row data of getting the first acquisition frame show as quasi-holographic, the second data rows that the secondary series data of getting the second acquisition frame show as quasi-holographic, the N data rows that the N column data getting N acquisition frame shows as quasi-holographic, the like, N is natural number.
When video acquisition, if image is a simple objects, be such as a bunch of flowers, can be placed on a rotating circular disk and rotate, and video camera is fixed; If object is very large, also can by video camera around image rotary taking.When video acquisition, multidigit double end video camera is adopted to take at circumference.When carrying out animation and making, simulate above-mentioned video acquisition process and carry out.
Beneficial effect of the present invention is:
The present invention adopts three-dimensional display as basic display, can adopt and show stereo-picture in various manners, uses special software according to the actual body display of the surrounding of object, realizes quasi-holographic display.Native system does not need high power laser, and brightness is very high, all can use in indoor and outdoor, and this is that other current holographic techniques do not reach.
Other advantages of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from the practice of the present invention.Target of the present invention and other advantages can be realized by structure specifically noted in instructions below or accompanying drawing and be obtained.
Accompanying drawing explanation
Fig. 1 is existing rotary-type cylindrical shape LED display system;
Fig. 2 is the display using multiple barcode LED display unit to make;
Fig. 3 is the cylindrical shape display that the present invention adopts rotary stereo display unit;
Fig. 4 is the cylindrical shape display that the present invention adopts multiple barcode LED stereoscopic display unit and forms;
Fig. 5 is for forming quasi holographic image data acquiring/procedure for displaying schematic diagram.
Embodiment
Also by reference to the accompanying drawings the present invention is described in further detail below by embodiment:
As depicted in figs. 1 and 2, existing rotating LED display system or use multiple barcode LED display unit to surround cylindrical shape display in, can only realize plane display, 3D stereo display cannot be completed.Using stereoscopic display unit or stereo display parts when being changed into by the display unit of display respectively, also changing three-dimensional display into by common 2D display.As shown in Figure 3 and Figure 4, now cylindrical shape display can realize plane display, also can realize 3D stereo display.Display is to be the displays such as polarization-type, bore hole type, electronic shutter type or double-colored type, and bore hole type adopts stereo display parts by display unit, and now display can realize bore hole stereo display.
As shown in Figure 3, Figure 4, when doing ordinary stereo display, 2 viewpoint 3D or three-dimensional signal such as 3D broadcast television signal or three-dimensional film data can be inputted, or input 2 viewpoint animation data-signals.Display screen can show circumference stereo-picture.
When needs realize quasi-holographic display, use video acquisition software or animation Software for producing etc., according to the actual body display of the surrounding of object, realize quasi-holographic display.Such as: the front such as face that people or thing can be seen above, see the back side of head around to below, the left side is left ear, and the right is auris dextra piece, also namely can see whole surrounding images of an object.When video acquisition, if image is a simple objects, be such as a bunch of flowers, can be placed on a rotating circular disk and rotate, and video camera is fixed; If object is very large, also can, by video camera around image rotary taking, further, multidigit double end video camera also can be adopted to take at circumference.When carrying out animation and making, simulate above-mentioned video acquisition process and carry out.When showing, the first data rows that the first row data of getting the first acquisition frame show as quasi-holographic, the second data rows that the secondary series data of getting the second acquisition frame show as quasi-holographic, the N data rows that the N column data getting N acquisition frame shows as quasi-holographic, the like, complete whole video acquisition or view data making and show, as shown in Figure 5.
Above embodiment is only for illustration of the preferred embodiment of the present invention; but the present invention is not limited to above-mentioned embodiment; in the ken that described exercising ordinary skill possesses; the any amendment done within the spirit and principles in the present invention, equivalent to substitute and improvement etc., it all should be encompassed within the technical scheme scope of request of the present invention protection.
