GS2E: Gaussian Splatting is an Effective Data Generator for Event Stream Generation

Existing event datasets are often synthesized from dense RGB videos, which typically lack viewpoint diversity and geometric consistency, or depend on expensive, difficult-to-scale hardware setups. GS2E overcomes these limitations by first reconstructing photorealistic static scenes using 3DGaussian Splatting, and subsequently employing a novel, physically-informed event simulation pipeline.
