针对带标注点云路缘数据稀缺的问题,提出结合深度分割网络与序列级里程计重建的 LiDAR 三维路缘检测方法,并生成符合 ASAM OpenLABEL 的预标注,使人工标注时间降低 50.99% 且质量不变。

摘要:

路缘检测对于自动驾驶(AD)中的环境感知至关重要,因为路缘通常界定了可行驶区域与不可行驶区域。标注数据是开发和验证 AD 功能所必需的。然而,带有点云路缘标注的公开数据集数量稀少。本文提出了一种在 LiDAR 传感器采集的点云序列中检测三维路缘的方法,该方法包括两个主要步骤。首先,本方法使用分割深度神经网络检测每次扫描中的路缘。随后,序列级处理步骤利用车辆里程计在重建点云中估计三维路缘。基于这些路缘三维点,我们获得按照 ASAM OpenLABEL 标准结构化的折线。这些检测结果可用作标注流程中的预标注,以高效生成与路缘相关的真值数据。我们通过一项实验验证了本方法:实验要求不同的人工标注员在有和没有我们自动生成的预标注两种情况下,对一组基于 LiDAR 的序列中的路缘进行标注。结果表明,得益于我们的检测结果,人工标注时间减少了 50.99%,同时保持了数据质量水平。

英文摘要:

Curb detection is essential for environmental awareness in Automated Driving (AD), as it typically limits drivable and non-drivable areas. Annotated data are necessary for developing and validating an AD function. However, the number of public datasets with annotated point cloud curbs is scarce. This paper presents a method for detecting 3D curbs in a sequence of point clouds captured from a LiDAR sensor, which consists of two main steps. First, our approach detects the curbs at each scan using a segmentation deep neural network. Then, a sequence-level processing step estimates the 3D curbs in the reconstructed point cloud using the odometry of the vehicle. From these 3D points of the curb, we obtain polylines structured following ASAM OpenLABEL standard. These detections can be used as pre-annotations in labelling pipelines to efficiently generate curb-related ground truth data. We validate our approach through an experiment in which different human annotators were required to annotate curbs in a group of LiDAR-based sequences with and without our automatically generated pre-annotations. The results show that the manual annotation time is reduced by 50.99% thanks to our detections, keeping the data quality level.
