DGGT: Feedforward 4D Reconstruction of Dynamic Driving Scenes using Unposed Images

arXiv — cs.CVWednesday, December 3, 2025 at 5:00:00 AM
  • The Driving Gaussian Grounded Transformer (DGGT) has been introduced as a novel framework for fast and scalable 4D reconstruction of dynamic driving scenes using unposed images, addressing the limitations of existing methods that require known camera calibration and per-scene optimization. This approach allows for reconstruction directly from sparse images and supports long sequences with multiple views.
  • This development is significant as it enhances the efficiency and flexibility of autonomous driving technologies, enabling better training and evaluation processes for autonomous vehicles. By reformulating camera pose as an output, DGGT improves the scalability of dynamic scene reconstruction.
  • The advancement of DGGT aligns with ongoing efforts in the autonomous driving sector to leverage large datasets like nuScenes and Waymo for improved scene understanding. As the industry moves towards more robust and generalized systems, innovations like DGGT and other frameworks aim to address challenges in scene perception and ego status, ultimately contributing to safer and more reliable autonomous driving solutions.
