Evidential occupancy grid maps (OGMs) are a popular representation of the
environment of automated vehicles. Inverse sensor models (ISMs) are used to
compute OGMs from sensor data such as lidar point clouds. Geometric ISMs show a
limited performance when estimating states in unobserved but inferable areas
and have difficulties dealing with ambiguous input. Deep learning-based ISMs
face the challenge of limited training data and they often cannot handle
uncertainty quantification yet. We propose a deep learning-based framework for
learning an OGM algorithm which is both capable of quantifying uncertainty and
which does not rely on manually labeled data. Results on synthetic and on
real-world data show superiority over other approaches.

基于模拟的证据占用网格映射的端到端学习框架
证据占用栅格地图(OGM)是自动驾驶汽车环境的一种流行表示形式。逆传感器模型(ISM)用于根据传感器数据(如激光雷达点云)计算OGM。几何ISM估计未观察到但可推断的区域中的状态时性能有限,并且难以处理模棱两可的输入。基于深度学习的ISM面临培训数据有限的挑战,并且它们通常还无法处理不确定性量化。我们提出了一种基于深度学习的框架,用于学习OGM算法,该算法既可以量化不确定性,又不依赖于手动标记的数据。综合数据和真实数据的结果显示出优于其他方法的优势。
