New diffusion models enhance LiDAR generation and recovery

By PulseAugur Editorial · [2 sources] ·

Two new research papers explore methods for improving LiDAR data generation and recovery using diffusion models. The first paper, CRISP, introduces a diffusion decoder to fix "flying pixels" in latent LiDAR generation, significantly reducing errors and narrowing the sim-to-real gap. The second paper leverages a pretrained Stable Diffusion model to recover LiDAR resolution from heavily decimated input, showing substantial accuracy gains in sparse regimes, particularly for planar surfaces. AI
