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.

我们提出了一个大规模的三维车道数据集 LiSV-3DLane，其中包含 2 万帧环视 LiDAR 点云，通过丰富的语义注释，捕捉了城市和高速公路环境中的复杂车道模式。为了解决稀疏的 LiDAR 数据在车道标注中的问题，我们利用车道线的几何特征和 LiDAR 数据的固有空间属性，设计了一个简单而有效的自动标注流程。我们还提出了一种新颖的基于 LiDAR 的三维车道检测模型 LiLaDet，将 LiDAR 点云的空间几何学习融入到基于 Bird's Eye View（BEV）的车道识别中。实验结果表明，LiLaDet 在 K-Lane 数据集和我们的 LiSV-3DLane 上的三维车道检测任务中优于现有的基于摄像头和 LiDAR 的方法。
