Abstract
The invention relates to a ball screen projection technology, in particular to a method for performing ball screen projection processing on a planar picture to be displayed by using a computer. The method comprises the following steps of: A, constructing a spherical model consistent with the shape of a ball screen; B, performing unfolding ultraviolet (UV) on the spherical model, and attaching the planar picture to be displayed to the spherical model to obtain a spherical picture to be displayed; and C, unfolding the spherical model to form a rectangle in which the longest weft on a spherical surface is used as the length and a warp is used as the width, and thus obtaining a rectangular picture to be projected. The key point is that inverse conversion is performed; the projection action of a projector is positive conversion; the spherical picture is subjected to the inverse conversion and then the positive conversion, so that the finally displayed content is the spherical picture to be displayed by projection; therefore, the phenomena of distortion and deformation which influence the appearance are avoided.
Description
Technical field
The application relates to ball-screen projection technology, especially with computing machine, plane figure to be shown is carried out to the method for ball-screen projection process.
Background technology
At present, hyperchannel ball-screen projection movie theatre rises.Traditional ball curtain Moviemaking method carries out shoot on location by loading fish eye lens on video camera.Play if directly the film HD video be made up of the former figure of plane not loading fish eye lens shooting is put in ball curtain system, serious torsional deformation will be produced when projecting on ball curtain, affect attractive in appearance.
Summary of the invention
The technical matters that the application will solve is the picture to be projected how drawing the torsional deformation attractive in appearance that not have an impact when ball curtain shows from plane figure to be shown.
Provide the method for ball-screen projection process being carried out to plane figure to be shown with computing machine for this reason, comprise the following steps:
A. the Sphere Measurement Model consistent with ball curtain shape is set up;
B. exhibition UV is carried out to Sphere Measurement Model, then figure to be shown for plane is attached on Sphere Measurement Model, obtain sphere figure to be shown;
C. Sphere Measurement Model is launched into the longest parallel of sphere for length, a warp is wide rectangle, obtains rectangle figure to be projected.
In stepb, carry out exhibition UV to Sphere Measurement Model, then figure to be shown for plane is attached on Sphere Measurement Model, obtain sphere figure to be shown, its picture material is exactly spherical diagram shown when projecting ball curtain.In step C, sphere figure to be shown is launched into the longest parallel of sphere as length along with Sphere Measurement Model, article one, warp is wide rectangle, obtains rectangle figure to be projected, and the conversion of figure is here equivalent to figure in the inverse conversion projecting to the conversion occurred in the process of ball curtain from projector.Therefore, as long as projector projects to figure to be projected for obtained rectangle on ball curtain, the spherical diagram before ball curtain just can demonstrate inverse conversion, namely project spherical diagram to display.Visible, key of the present invention has carried out above-mentioned inverse conversion, and projector carry out projection This move carry out exactly " suitable " conversion, above-mentioned spherical diagram is changed by " suitable " after being reversed and changing again, therefore final display is exactly the spherical diagram to display that projects, would not have an impact torsional deformation attractive in appearance.
Accompanying drawing explanation
Fig. 1 is Sphere Measurement Model schematic diagram.
Fig. 2 is the former figure of plane.
Fig. 3 is plane figure to be shown.
Fig. 4 is the Local map of sphere figure to be shown.
Fig. 5 is rectangle figure to be projected.
Embodiment
With computing machine, plane figure to be shown is carried out to the method for ball-screen projection process.Steps A was performed before following step B. set up the Sphere Measurement Model consistent with ball curtain shape, as shown in Figure 1.
Also needed to determine plane figure to be shown before step B, the determination of plane figure to be shown and the execution sequence of steps A are in no particular order.In order to show in ball scene plot face, the viewing area that preferably taking-up one is circular from plane former figure is as plane figure to be shown.If the former figure of plane is circular, then directly take out, but the former figure of the plane shown in Fig. 2 is rectangle, therefore the present embodiment carries out compression to the former figure of plane on the direction of rectangular length draws foursquare figure, gets the plane figure to be shown that this foursquare incircle can obtain as shown in Figure 3.In other embodiments, stretching is carried out to the former figure of plane in rectangular wide direction and draws foursquare figure, get this foursquare inscribe fenestra and can obtain required plane figure to be shown; Or on the former figure of plane, foursquare figure is shown to the brachymemma of rectangular progress row, get this foursquare incircle and obtain required plane figure to be shown.
Then perform step B. and exhibition UV is carried out to Sphere Measurement Model, then figure to be shown for plane is attached on Sphere Measurement Model, obtains sphere figure to be shown as shown in Figure 4.
Then performing step C. is launched into Sphere Measurement Model with the longest parallel of sphere for length, and a warp (it is to the right that this warp is shown in Fig. 4 central authorities) is wide rectangle, obtains rectangle figure to be projected as shown in Figure 5.
In order to carry out hyperchannel projection, just needing multiple stage projector and investing same ball curtain, Mei Tai projector is responsible for projecting out the part of spherical diagram to display, and these incorporating aspects become complete spherical diagram.Perform step D. for this reason and distribute to corresponding projector according to the view field of Ge Tai projector on ball curtain after picture segmentation to be projected.
Below be only the preferred embodiment of the application, equivalent technical solutions on this basis still falls into application protection domain.
