DGS-LRM: Real-Time Deformable 3DGaussian Reconstruction From Monocular Videos

We introduce the Deformable Gaussian Splats Large Reconstruction Model (DGSLRM), the first feed-forward method predicting deformable 3DGaussian splats from a monocular posed video of any dynamic scene. Feed-forward scene reconstruction has gained significant attention for its ability to rapidly create digital replicas of real-world environments. However, most existing models are limited to static scenes and fail to reconstruct the motion of moving objects. Developing a feed-forward model for dynamic scene reconstruction poses significant challenges, including the scarcity of training data and the need for appropriate 3D representations and training paradigms.
