Embodiment Construction

[0031] In order to solve the problems of high rendering cost and complicated calculation in the prior art, the present invention provides a method for generating fisheye effect pictures by using multiple cameras. The core of the method is: the present invention adopts optical principles and Graphics technology, according to the corresponding relationship between the real field of view and imaging, divides the process of generating the fisheye effect into two steps. First, 9 cameras are used to combine pictures from different perspectives, and one of the cameras is placed on the other 8 cameras. The middle is used as a positioning reference, and the other 8 cameras placed adjacent to it are rotated at different angles, and the pictures taken by the 9 cameras at different angles are rendered, and the corresponding spatial positions are projected onto the plane using the projection method and merged to generate two-dimensional graphics to edit the combined image in a two-dimension...

Abstract

The invention discloses a method for generating an image with a fisheye effect by utilizing a plurality of video cameras, and relates to a digital film technology, in particular to the method for shooting a real field of view by utilizing nine video cameras to generate the image with the fisheye effect by adopting an optical principle and a computer graphics technology. The method is suitable forprojection imaging on a curved screen. The method comprises the following steps of: combining and arranging the nine video cameras, wherein one video camera is arranged in a center as a positioning reference video camera around which the other eight video cameras at different angles are uniformly distributed; and acquiring images of different visual angles by utilizing the nine video cameras in acombined way, combining the images rendered by the nine video cameras, and performing deformation processing on the combined image to obtain the image with the fisheye effect. By the method, semispherical images can be seamlessly jointed in a way of combined shooting of specific angles by adopting the plurality of video cameras, image rendering cost is low and operations are simple; and the method is suitable for projecting real image frames on the curved screen.

Description

technical field [0001] The invention relates to digital film technology, in particular to a method of using optical principles and computer graphics technology to shoot a real field of view with nine cameras to generate a picture with a fish-eye effect suitable for projection imaging on a curved screen. Background technique [0002] With the continuous development of high-tech entertainment equipment, many new types of entertainment equipment have emerged. Among them, the hemispherical screen movie, its huge curved screen can surround the audience, so that the audience has an immersive feeling; There are different shooting and production methods, mainly including live shooting with fisheye camera, full digital production, or co-production of real scene and digital. [0003] Fisheye is used to shoot real scenes, and digital production also needs to use fisheye effects to match it. There are several methods for digitally producing fisheye effects, but each has its own shortco...
