PanDORA system captures high dynamic range radiance for realistic image-based lighting

Researchers have developed PanDORA, a system for rapidly capturing high dynamic range (HDR) radiance maps essential for realistic image-based lighting. Unlike existing methods that rely on slow exposure bracketing or low dynamic range imagery, PanDORA uses two synchronized 360° cameras to record videos at different exposures. A novel two-stage NeRF-based algorithm processes these videos, including a self-calibrating pipeline, to generate accurate HDR radiance fields. AI
