Samsung patents method to map real-world lighting using AI
Samsung describes a system that uses multiple cameras to build a 3D model of a physical space and places a virtual sphere inside it to estimate how light behaves. It then uses an AI diffusion model to refine this rough estimate into a detailed map of the scene's lighting.
In the filing’s own words
A method for estimating a light map of real-world scene is provided. The method includes receiving a plurality of images corresponding to the real-world scene by a plurality of cameras, generating a 3-dimensional (3D) representation of the real-world scene based on the received plurality of images, positioning a virtual sphere within the generated 3D representation of the real-world scene, estimating a coarse light map of the real-world scene on the virtual sphere, generating at least one 2-dimensional (2D) image corresponding to the virtual sphere with the estimated coarse light map estimating an enhanced virtual sphere by operating the at least one generated 2D image based on a pre-trained diffusion model, and estimating the light map of the real-world scene based on the enhanced virtual sphere.
What exactly they claim (claim 1)
1. A method for estimating a light map of a real-world scene, the method comprising: receiving a plurality of images corresponding to the real-world scene by a plurality of cameras; generating a 3-dimensional (3D) representation of the real-world scene based on the received plurality of images; positioning a virtual sphere within the generated 3D representation of the real-world scene; estimating a coarse light map of the real-world scene on the virtual sphere; generating at least one 2-dimensional (2D) image corresponding to the virtual sphere with the estimated coarse light map; estimating an enhanced virtual sphere by operating the at least one generated 2D image based on a pre-trained diffusion model; and estimating the light map of the real-world scene based on the enhanced virtual sphere.
