DynamicCity: Large-Scale 4D Occupancy Generation from Dynamic Scenes

Understand

Urban scene generation has been developing rapidly recently.

• However, existing methods primarily focus on generating static and single-frame scenes, overlooking the inherently dynamic nature of real-world driving environments.
• In this work, we introduce DynamicCity, a novel 4D occupancy generation framework capable of generating large-scale, high-quality dynamic 4D scenes with semantics.
• DynamicCity mainly consists of two key models.
