==IMAGE RECONSTRUCTION WITH VIEW-DEPENDENT SURFACE IRRADIANCE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240046556 titled 'IMAGE RECONSTRUCTION WITH VIEW-DEPENDENT SURFACE IRRADIANCE

==Simplified Explanation==

The abstract describes a computer-implemented method that involves receiving visible-light images captured from different viewpoints using visible-light cameras. A 3D model of a real-world environment is created, where the model stores color information related to the surfaces of real objects. The 3D points on the surfaces of the objects are divided into groups based on factors such as the angle between surface normals, differences in materials, and differences in textures. For each group of 3D points, at least two visible-light images are determined, which represent different surface irradiances of the group. Information indicating these different surface irradiances is stored in the 3D model.

* The method involves creating a 3D model of a real-world environment using visible-light images captured from different viewpoints.
* The 3D model stores color information pertaining to the surfaces of real objects.
* The 3D points on the surfaces of the objects are divided into groups based on factors such as surface normals, materials, and textures.
* For each group of 3D points, at least two images are determined, representing different surface irradiances.
* Information indicating these different surface irradiances is stored in the 3D model.

Potential Applications:
* Augmented reality: The 3D model can be used to overlay virtual objects onto the real-world environment, enhancing the user's perception of reality.
* Virtual reality: The 3D model can be utilized to create immersive virtual environments that accurately represent real-world surfaces and objects.
* Computer graphics: The 3D model can be used for realistic rendering and simulation of real-world scenes in movies, video games, and other visual media.

Problems Solved:
* Accurate representation of real-world surfaces: The method allows for the creation of a 3D model that stores color information, providing a more realistic representation of real objects and their surfaces.
* Surface irradiance variation: By determining different surface irradiances for groups of 3D points, the method addresses the challenge of capturing and representing variations in surface lighting conditions.

Benefits:
* Enhanced visual realism: The method improves the visual realism of augmented reality, virtual reality, and computer graphics applications by accurately representing the color and lighting variations of real-world surfaces.
* Improved user experience: Users of augmented reality and virtual reality applications can benefit from a more immersive and believable experience due to the accurate representation of real objects.
* Increased efficiency: The method automates the process of creating a 3D model and determining surface irradiances, saving time and effort compared to manual methods.
