Glasses‐Free 3D Content Generation Based on Gaussian Splatting and Off‐Axis Camera Array

ABSTRACT Content generation is a key element in the field of 3D display. Currently, most 3D display content is limited to virtual scenes, and the production of such content requires a huge amount of time for modeling. In contrast, the capture of real‐world scene content relies on camera arrays, which not only involve a complex operation process but also face the problem of high equipment costs. This study proposes a method for generating multiview glasses‐free 3D content using Gaussian splatting. The method to achieve a glasses‐free 3D display is using lenticular lenses and LCD screens. Then, Gaussian splatting is used to reconstruct the real‐world scene. Next, the method to generate off‐axis cameras is introduced, and a virtual camera array is added to the reconstructed 3D scene to render multiview disparity images. Finally, multiview 3D images can be synthesized based on these disparity images. This work makes it more convenient and low‐cost to obtain disparity images in real‐world scenes, which will contribute to enriching the content of glasses‐free 3D displays and boost the development of glasses‐free 3D technology.
