ReconDreamer: Crafting World Models for Driving Scene Reconstruction via Online Restoration

CVPR 25 2025 65.2 method, application

TLDR

ReconDreamer enhances driving scene reconstruction for novel trajectories by incrementally integrating world model knowledge with online restoration.

Reasoning

The paper introduces a novel method for handling complex maneuvers in driving scene reconstruction, supported by strong quantitative improvements over baselines. However, the abstract lacks details on the world model architecture and limitations of the approach.

Methodology

ReconDreamer enhances driving scene reconstruction by incrementally integrating world model knowledge. It uses DriveRestorer for online restoration of artifacts and a progressive data update strategy to ensure high-quality rendering for complex maneuvers. The model is evaluated on driving scenes with novel trajectories.

Key Results

ReconDreamer outperforms Street Gaussians in NTA-IoU, NTL-IoU, and FID with relative improvements of 24.87%, 6.72%, and 29.97%. It also surpasses DriveDreamer4D with PVG during large maneuver rendering, achieving a 195.87% relative improvement in NTA-IoU and confirmed by a user study.
