A 5d360° ring screen digital high-definition stereoscopic film production method

Abstract

The present invention provides a 5D360° ring-screen digital high-definition three-dimensional film production method, using the existing three-dimensional animation production software to determine the actual radius (R) and height (H) of the 360° ring screen, and calculate the number of sub-screens ( S), the number of grid bars (G) and observation point distance (L) of each sub-screen image, by setting the distance (D) between two analog cameras and setting rendering parameters, the three-dimensional data of each grid bar Render each frame of the model and scene, output two high-definition image grids for the left eye and the right eye, seamlessly stitch multiple high-definition image grids in sequence to form the left-eye and right-eye high-definition images on the screen, and perform deformation Correction, splicing and fusion processing of the edges of each sub-screen image, realizing the splicing of multiple sub-screen high-definition images into a 360° complete three-dimensional high-definition image. Produce great shock.

Description

technical field [0001] The invention relates to digital movie technology, in particular to a 5D360° ring-screen digital high-definition three-dimensional movie production method using three-dimensional animation technology. Background technique [0002] The production of traditional surround-screen stereoscopic high-definition movies usually sets the number of stereoscopic cameras according to the number of projectors (usually six). This production technology can only produce stereoscopic images with a flat imaging surface due to the constraints of hardware and software. , the resulting problems have three aspects: ① First, it will bring about the problem of limited viewing angle. The stereoscopic image produced by this technology has a strong stereoscopic effect within a certain viewing angle range, and once it exceeds this viewing angle range, the audience will The three-dimensional perception will be greatly weakened. This is because people's visual imaging surface is ar...

[0002] The production of traditional surround-screen stereoscopic high-definition movies usually sets the number of stereoscopic cameras according to the number of projectors (usually six). This production technology can only produce stereoscopic images with a flat imaging surface due to the constraints of hardware and software. , the resulting problems have three aspects: ① First, it will bring about the problem of limited viewing angle. The stereoscopic image produced by this technology has a strong stereoscopic effect within a certain viewing angle range, and once it exceeds this viewing angle range, the audience will The three-dimensional perception will be greatly weakened

②Secondly, there is the problem of viewing point limitation. The reason is the same as above, that is, when the image is played, the three-dimensional effect is strong when viewed within a specific observation range, but once the viewer's viewing position is not within this observation range, the three-dimensional effect will be greatly weakened.

③Finally, there is the problem of visual fatigue. Since a part of the image generated by this production technology must not be on the human visual imaging surface, the lens of the audience is always in a state of continuous focus when watching the film, which can easily cause visual fatigue. viewing effect

[0003] Due to the technical limitations of the imaging surface, the traditional ring-screen stereoscopic high-definition film production technology will inevitably cause the objects rendered in a certain range before the imaging surface to be unable to focus continuously and accurately. The resulting problems have two aspects: ①First There will be problems of image discontinuity and seams of each imaging surface, that is, the images generated by each imaging surface have cracks, especially for nearby objects, and at the same time, each imaging surface will have a seam problem when it is finally projected and played

②Secondly, there is the problem of the strength of the visual stereoscopic effect, which makes it necessary to adjust the simulated interpupillary distance of the left and right eye cameras at certain times during the production to control the visual stereoscopic effect. Although the visual stereoscopic effect is enhanced, it will intensify the first ① The problem arises, making the first problem more obvious

Sometimes the stereoscopic effect is very different from the real theater stereoscopic effect, and it needs to pay a lot of cost to test the stereoscopic effect after adjusting in the software, rendering, and re-projecting the test until the stereoscopic effect is perfect.
