DriveSceneGen: Generating Diverse and Realistic Driving Scenarios From Scratch

Realistic and diverse traffic scenarios in large quantities are crucial for the development and validation of autonomous driving systems. However, owing to numerous difficulties in the data collection process and the reliance on intensive annotations, real-world datasets lack sufficient quantity and diversity to support the increasing demand for data. This work introduces
DriveSceneGen
, a data-driven driving scenario generation method that learns from the real-world driving dataset and generates entire dynamic driving scenarios from scratch. Experimental results on 5k generated scenarios highlight that
DriveSceneGen
is able to generate novel driving scenarios that align with real-world data distributions with high fidelity and diversity. To the best of our knowledge,
DriveSceneGen
is the first method that generates novel driving scenarios involving both static map elements and dynamic traffic participants from scratch. Extensive experiments demonstrate that our two-stage method outperforms existing state-of-the-art map generation methods and trajectory simulation methods on their respective tasks.
