Explore illumination reconstruction methodologies for 3D scenes in this technical talk that presents three distinct techniques for capturing and reconstructing radiometric information. Learn about a specialized hardware approach using wide-angle imagery and image processing to detect light sources, discover a mobile-based method for capturing omnidirectional scene illumination in high dynamic range using standard phone cameras, and understand how deep learning networks can estimate illumination from single scene images. Gain insights into practical applications of these illumination estimation methods across augmented reality, scene understanding, and 3D scene relighting domains.
