MapRF uses NeRF-guided self-training for weakly supervised HD map construction

Researchers have developed MapRF, a novel framework for constructing high-definition (HD) maps for autonomous driving systems using only 2D image labels. This weakly supervised approach leverages Neural Radiance Fields (NeRF) to generate pseudo-labels, which are then used to iteratively refine the map network through self-training. A key component, Map-to-Ray Matching, helps align map predictions with camera rays to reduce errors. Experiments on the Argoverse 2 and nuScenes datasets show MapRF achieves performance comparable to fully supervised methods, making HD map construction more scalable and cost-effective. AI

影响 Enables more scalable and cost-effective HD map construction for autonomous driving by reducing reliance on costly 3D annotations.
