Researchers have developed ARETE, a new method for generating High-Definition (HD) maps for autonomous driving using crowdsourced vehicle data. The approach employs a Detection Transformer (DETR) model to predict vectorized lane representations, including centerlines and lane dividers, from rasterized vehicle trajectories. This technique aggregates local trajectory data, transforms it into a rasterized format encoding presence and direction, and then predicts geometrically constrained lanes. Experiments were conducted on internal datasets and public benchmarks like nuScenes and nuPlan. AI
