Problems solved by technology

[0007] (2) Since it is practically impossible to make all photographic observation points overlap during shooting, it is practically impossible for the images on adjacent screens to be connected together completely and continuously
[0008] (3) The difference in the small optical parameters of the projector and the film will also cause the picture to be discontinuous
When using the 3D animation method to make a film, the 3D animation software uses rendering to simulate the photographic imaging process, but all commercial 3D animation software can only render on a plane

Embodiment Construction

[0031] The manufacturing method of the present invention will be further described below in conjunction with the accompanying drawings.

[0032] This article uses the term "disparity model" to refer to mathematical methods that artificially establish disparity. Through the analysis of common three-dimensional film technology, it can be summarized as follows: figure 1 The normal disparity model shown.

[0033] The straight line connecting the observation points of the two cameras is called the "baseline". In order to form parallax, the length of the baseline should be equivalent to the distance between the pupils of the two eyes of a person, which is called the "pupillary distance". The baseline is horizontal and perpendicular to the viewing direction.

[0034] The axes of the two cameras are nearly parallel, and the intersection of the two axes is always in front of the camera. The distance from the intersection point to the baseline is called the "object distance", and it ...

Abstract

A digital producing mehtod of uring screen stereoscopic film is on the bases of three-dimensional cartoon producing system by setting up a cylindrical surface made up with M X N narrow strips in the space definited by the three-dimensional model. For each frame of a film to be produced, one will make exaggration to the three-dimensional scene corresponding to each narrow strip and output two narrow strips of images and arrange the 2XM narrow strip images of said each frame to a frame of subscreen image, and to make distortion rectification and seamless arrangement to finish the image papers to enable to show the complete stereoscopic image on 180-360 deg. cylindrical sarfaced screen with continuously and distinctly frame and magical new action effect to generate magic and astonishing ideas.

Description

technical field [0001] The invention relates to digital film and television technology, in particular to a method for making digital ring-screen stereoscopic film using three-dimensional animation technology. Background technique [0002] Traditional stereoscopic movies are shot with dual cameras or dual-lens cameras, and the corresponding observation points are staggered by a few centimeters along a horizontal line perpendicular to the observation direction to generate parallax. The distance between the two observation points (interpupillary distance) should be equivalent to the distance between the eyes of a person. [0003] When projecting, the left and right channel images corresponding to the left and right eyes of the people are shown respectively by two movie projectors, and are projected onto the same screen. Add a polarizing film in front of the projector lens to make the two images have different polarization directions. Using a screen with a certain specular ref...
