MapDreamer: Aerial Imagery Conditioned Latent Diffusion for Lane-Level Map Generation
Julian Brandes, Philipp Crocoll, Wolfram Burgard
High definition map generation is essential for autonomous driving, yet remains a labor-intensive process at scale. We present MapDreamer, a generative diffusion model that synthesizes lane-level vector maps with explicit topology directly from a single aerial image. MapDreamer l…
