Digital Twin Catalog: A Large-Scale Photorealistic 3D Object Digital Twin Dataset

Figure 1 . The Digital Twin Catalog (DTC) dataset comprises 2,000 digital twins of physical-world objects (a), characterized by millimeterlevel geometric accuracy and photorealistic PBR materials (b). DTC includes evaluation data captured using both DSLR cameras and egocentric Aria glasses, featuring captured images with precise foreground object masks and environment lighting for relighting evaluation.
