Key Points

DriveFix addresses the lack of spatio-temporal coherence in multi-view driving scene restoration by using an interleaved diffusion transformer that models temporal dependencies and cross-camera spatial consistency.
The framework conditions restoration on historical context and uses geometry-aware training losses to enforce alignment with a unified 3D geometry, reducing artifacts and enabling texture propagation across views.
It achieves state-of-the-art performance in both reconstruction and novel view synthesis on Waymo, nuScenes, and PandaSet, signaling strong potential for robust 4D world modeling in real-world deployment.
The work highlights the importance of joint spatio-temporal multi-view modeling for autonomous driving perception and may influence future research and deployment strategies.

Abstract

Recent advancements in 4D scene reconstruction, particularly those leveraging diffusion priors, have shown promise for novel view synthesis in autonomous driving. However, these methods often process frames independently or in a view-by-view manner, leading to a critical lack of spatio-temporal synergy. This results in spatial misalignment across cameras and temporal drift in sequences. We propose DriveFix, a novel multi-view restoration framework that ensures spatio-temporal coherence for driving scenes. Our approach employs an interleaved diffusion transformer architecture with specialized blocks to explicitly model both temporal dependencies and cross-camera spatial consistency. By conditioning the generation on historical context and integrating geometry-aware training losses, DriveFix enforces that the restored views adhere to a unified 3D geometry. This enables the consistent propagation of high-fidelity textures and significantly reduces artifacts. Extensive evaluations on the Waymo, nuScenes, and PandaSet datasets demonstrate that DriveFix achieves state-of-the-art performance in both reconstruction and novel view synthesis, marking a substantial step toward robust 4D world modeling for real-world deployment.
