FrozenDrive: Zero-Shot Text-Guided Driving Scene Generation and Data Augmentation with Parameter-Free Frozen Diffusion Model
Summary
FrozenDrive is a controllable generative framework designed to enhance synthetic data generation for autonomous driving by addressing key limitations of existing diffusion models. It tackles challenges like maintaining multi-view and temporal consistency, and improving performance under adverse weather or rare scene configurations, without fine-tuning the backbone. FrozenDrive achieves this by preserving pre-trained diffusion model knowledge, conditioning on rich driving-stack signals and text prompts, and introducing knowledge-preserving spatio-temporal attention. This attention mechanism imposes cross-view alignment and temporal coherence in a single pass within a parameter-free frozen diffusion backbone. An additional object-focused constraint improves per-object fidelity for rare categories. The model synthesizes globally coherent multi-view driving scenes from text, outperforming prior baselines, especially in adverse conditions. On nuScenes, FrozenDrive-augmented data significantly improves AD model performance, particularly at night and in rain, demonstrating stronger robustness.
Key takeaway
For autonomous driving (AD) model developers aiming to enhance robustness in challenging conditions, you should consider integrating synthetic data generated by frameworks like FrozenDrive. This approach allows you to create scenario-targeted data, particularly for adverse weather or rare events, without extensive fine-tuning. Leveraging such augmented datasets can significantly improve your AD models' performance, especially at night and in rain, leading to more reliable systems.
