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

By PulseAugur Editorial · [1 sources] ·

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

IMPACT Introduces a more efficient method for capturing realistic lighting data, potentially improving rendering quality in computer graphics and virtual environments.

    PanDORA: Casual HDR Radiance Acquisition of Indoor Scenes for Image-based Lighting

    arXiv:2407.06150v3 Announce Type: replace Abstract: Most novel view synthesis methods -- including Neural Radiance Fields (NeRF) -- struggle to capture the high dynamic range (HDR) radiance required for realistic image-based lighting (IBL). This limitation stems from a reliance o…
