摘要:

在汽车工业标准下使用传感器进行3D感知是自动驾驶的刚性需求。MEMS激光雷达因其成本低、性能好、符合量产标准而成为不可阻挡的趋势。然而,它的视场(FoV)较小,减缓了其人口的步伐。在本文中,我们提出了铅,即,LiDAR Extender for Autonomous Driving,通过耦合图像w.r.t FoV和范围来扩展MEMS LiDAR。提出了一种基于深度分布和不确定性映射的多阶段传播策略,显示了有效的传播能力。此外,我们的深度outpainting/传播网络遵循师生训练的方式,它转移深度估计能力的深度完成网络没有任何规模误差通过。为了验证LiDAR扩展的质量,我们利用高精度的激光扫描仪来生成地面实况数据集。定量和定性的评估表明,我们的计划优于SOTA有很大的利润。我们相信拟议的LEAD和数据集将有利于社区进行深入研究。

英文摘要:

3D perception using sensors under vehicle industrial standard is the rigid demand in autonomous driving. MEMS LiDAR emerges with irresistible trend due to its lower cost, more robust, and meeting the mass-production standards. However, it suffers small field of view (FoV), slowing down the step of its population. In this paper, we propose LEAD, i.e., LiDAR Extender for Autonomous Driving, to extend the MEMS LiDAR by coupled image w.r.t both FoV and range. We propose a multi-stage propagation strategy based on depth distributions and uncertainty map, which shows effective propagation ability. Moreover, our depth outpainting/propagation network follows a teacher-student training fashion, which transfers depth estimation ability to depth completion network without any scale error passed. To validate the LiDAR extension quality, we utilize a high-precise laser scanner to generate a ground-truth dataset. Quantitative and qualitative evaluations show that our scheme outperforms SOTAs with a large margin. We believe the proposed LEAD along with the dataset would benefit the community w.r.t depth researches.
