摘要:

我们提出了一个异构定位框架,用于解决雷达全球定位和姿态跟踪预建激光雷达地图。为了弥合传感模式的差距,构建了深度神经网络,为雷达扫描和激光雷达地图创建共享的嵌入空间。在这里,学习的特征嵌入支持相似性度量,从而分别提高地图检索和数据匹配。在RobotCar和MulRan数据集中,我们通过与Scan Context和RaLL的比较证明了所提出的框架的有效性。此外,与原始RaLL相比,所提出的姿态跟踪流水线具有更少的神经网络。

英文摘要:

We present a heterogeneous localization framework for solving radar global localization and pose tracking on pre-built lidar maps. To bridge the gap of sensing modalities, deep neural networks are constructed to create shared embedding space for radar scans and lidar maps. Herein learned feature embeddings are supportive for similarity measurement, thus improving map retrieval and data matching respectively. In RobotCar and MulRan datasets, we demonstrate the effectiveness of the proposed framework with the comparison to Scan Context and RaLL. In addition, the proposed pose tracking pipeline is with less neural networks compared to the original RaLL.
