Implementation method and system for projecting and showing of ball screen

Abstract

The invention relates to an implementation method and an implementation system for projecting and showing of a ball screen, which are used for showing in a ball screen theater of which the ball screen is arranged at the top. The method mainly comprises the following steps of: re-showing scene pictures in a virtual ball screen theater, wherein the virtual ball screen theater is proportional to the ball screen theater; arranging a first virtual camera and a second virtual camera at positions of the virtual ball screen theater, wherein the positions of the virtual ball screen theater correspond to projectors in the actual ball screen theater; and respectively recording pictures showed on a first half of the virtual ball screen theater and a second half of the virtual ball screen theater, so that the scene pictures are re-showed on the ball screen theater by means of a first projector and a second projector. According to the method provided by the invention, a fisheye lens is not required, so that a central optimal observation position in the ball screen theater is not required, and the arrangement of theater seats is subjected to more optimization; moreover, virtual spherical convex lenses are arranged in front of the virtual cameras and are used for expanding the view of the cameras, and concave lenses are arranged in front of the projectors and are used for realizing deformation compensation of the spherical convex lenses, so that a display effect is ensured.

Description

technical field [0001] The present invention relates to dome projection technology, and more specifically, to a method and system for realizing dome projection projection. Background technique [0002] Dome film is a new form of film that has developed rapidly in recent years. The projection hall of the dome movie is a dome structure, and the projection screen is hemispherical, and the audience is surrounded by it. Because the screen image is large and clear, and the white audience extends from the front to the back, accompanied by stereo surround sound, the audience feels as if they are in it, and the on-the-spot effect is very strong. Therefore, dome movies have also become an increasingly popular form of entertainment. [0003] The shooting and projection principles of the dome movie will be described below by taking the three-dimensional virtual image as an example. First, use the virtual story scene constructed by 3D software, and use a set of virtual cameras to reco...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a method and system for realizing projection and projection on a dome screen, aiming at the defect that a fisheye lens needs to be installed at the center of the dome screen to occupy a better position for the existing dome screen projection. Two projectors in the theater project images to the upper and lower hemispheres of the dome respectively to optimize the theater setup
