Beyond Endpoints: Path-Centric Reasoning for Vectorized Off-Road Network Extraction

  • 采用路径为中心的思路,融合多尺度视觉证据推理连接关系
  • 在新构建的WildRoad数据集上达到最优性能,比现有方法提升显著
  • 适合野外地图构建、自动驾驶等复杂地形应用

深度学习已推动城市道路的矢量化提取进展,但野外环境仍缺乏研究且极具挑战。主要瓶颈在于缺乏大规模矢量数据集,以及现有方法结构薄弱。如SAM-Road采用节点中心范式,在稀疏端点处推理,对遮挡和模糊交汇处敏感,易产生拓扑错误。本文从两方面改进:首先,开发了专用交互标注工具,高效构建了全球性的野外道路网络数据集WildRoad;其次,提出MaGRoad(Mask-aware Geodesic Road network extractor),一种路径中心框架,通过沿候选路径聚合多尺度视觉证据,实现鲁棒的连通性推断。大量实验表明,MaGRoad在具有挑战性的WildRoad基准上达到当前最佳表现,并能良好泛化至城市数据集。高效的顶点提取策略使推理速度提升约2.5倍,增强实用性。数据集与代码已开源。

原文摘要 · Abstract (English)

Deep learning has advanced vectorized road extraction in urban settings, yet off-road environments remain underexplored and challenging. A significant domain gap causes advanced models to fail in wild terrains due to two key issues: lack of large-scale vectorized datasets and structural weakness in prevailing methods. Models such as SAM-Road employ a node-centric paradigm that reasons at sparse endpoints, making them fragile to occlusions and ambiguous junctions in off-road scenes, leading to topological errors. This work addresses these limitations in two complementary ways. First, we release WildRoad, a global off-road road network dataset constructed efficiently with a dedicated interactive annotation tool tailored for road-network labeling. Second, we introduce MaGRoad (Mask-aware Geodesic Road network extractor), a path-centric framework that aggregates multi-scale visual evidence along candidate paths to infer connectivity robustly. Extensive experiments show that MaGRoad achieves state-of-the-art performance on our challenging WildRoad benchmark while generalizing well to urban datasets. An efficient vertex extraction strategy also yields roughly 2.5X faster inference, improving practical applicability. Together, the dataset and path-centric paradigm provide a stronger foundation for mapping roads in the wild. We release both the dataset and code at this repository. We release both the dataset and code at https://github.com/xiaofei-guan/MaGRoad.
