DPCS: Path Tracing-based Differentiable Projector-Camera Systems

This IEEE conference talk presents DPCS (Path Tracing-based Differentiable Projector-Camera Systems), a novel approach for simulating projector-camera systems crucial for spatial augmented reality applications. Learn how the authors from Southwest University and Stony Brook University model the physical project-and-capture process using differentiable physically-based rendering, allowing scene parameters to be explicitly decoupled and learned. Discover the advantages of DPCS over previous approaches, including better interpretability, more efficient handling of complex interreflection and shadow, and reduced training sample requirements. The 10-minute presentation is part of the "Display Technologies and Rendering Techniques" session at IEEE VR 2025.
