Researchers have developed GSRAIN, a novel method for synthesizing realistic rainfall in 3D Gaussian Splatting (3DGS) driving scenes. This technique integrates a high-frequency raindrop model derived from real-world data with a geometry-aware diffusion model for low-frequency atmospheric effects. GSRAIN allows for precise control over rainfall intensity, ranging from 0 to 13 mm/h, and has demonstrated superior performance in terms of Fréchet Inception Distance compared to existing methods like CycleGAN-Turbo and WeatherEdit. The generated scenes have been validated through object-detection and closed-loop driving experiments, proving their utility in creating controllable and repeatable test environments for autonomous driving systems.
