针对LiDAR点云3D车道检测数据稀缺和标注困难,提出大规模数据集LiSV-3DLane及自动标注流程,并开发模型LiLaDet,在多个数据集上优于现有方法。

摘要:

高级驾驶辅助系统(ADAS)已成功将基于学习的技术集成到车辆感知和决策中。然而,它们在3D车道检测中的应用,以有效感知驾驶环境,却因缺乏全面的LiDAR数据集而受到阻碍。LiDAR点云数据的稀疏性使得高效的人工标注过程难以实现。为解决这一问题,我们提出了LiSV-3DLane,一个大规模3D车道数据集,包含20k帧环视LiDAR点云,并带有丰富的语义标注。与现有局限于前视的数据集不同,LiSV-3DLane提供了自车周围完整的360度空间全景,捕捉了城市和高速公路环境中的复杂车道模式。我们利用车道线的几何特征和LiDAR数据的内在空间属性,设计了一个简单而有效的自动标注流程,以生成更精细的车道标签。为推动未来研究,我们提出了一种新颖的基于LiDAR的3D车道检测模型LiLaDet,将LiDAR点云的空间几何学习融入基于鸟瞰图(BEV)的车道识别中。实验结果表明,在K-Lane数据集和我们的LiSV-3DLane上,LiLaDet在3D车道检测任务中优于现有的基于相机和基于LiDAR的方法。

英文摘要:

Advanced Driver-Assistance Systems (ADAS) have successfully integrated learning-based techniques into vehicle perception and decision-making. However, their application in 3D lane detection for effective driving environment perception is hindered by the lack of comprehensive LiDAR datasets. The sparse nature of LiDAR point cloud data prevents an efficient manual annotation process. To solve this problem, we present LiSV-3DLane, a large-scale 3D lane dataset that comprises 20k frames of surround-view LiDAR point clouds with enriched semantic annotation. Unlike existing datasets confined to a frontal perspective, LiSV-3DLane provides a full 360-degree spatial panorama around the ego vehicle, capturing complex lane patterns in both urban and highway environments. We leverage the geometric traits of lane lines and the intrinsic spatial attributes of LiDAR data to design a simple yet effective automatic annotation pipeline for generating finer lane labels. To propel future research, we propose a novel LiDAR-based 3D lane detection model, LiLaDet, incorporating the spatial geometry learning of the LiDAR point cloud into Bird's Eye View (BEV) based lane identification. Experimental results indicate that LiLaDet outperforms existing camera- and LiDAR-based approaches in the 3D lane detection task on the K-Lane dataset and our LiSV-3DLane.
