摘要:

使用公开访问的地图,我们提出了一种新的车辆定位方法,可以应用,而不使用事先的光检测和测距(LiDAR)地图。我们的方法通过计算从OpenStreetMap中的位置以常规角度到建筑物的距离来生成OSM描述符,并通过计算从当前位置以常规角度到建筑物点的最短距离来生成LiDAR描述符。比较OSM描述符和LiDAR描述符产生高度准确的车辆定位结果。与使用先前LiDAR地图的方法相比,我们的方法具有两个主要优点:(1)车辆定位不仅限于先前获得LiDAR地图的地方,(2)我们的方法与基于LiDAR地图的方法相当,特别是在KITTI数据集序列00的前一个候选人方面优于其他方法。

英文摘要:

Using publicly accessible maps, we propose a novel vehicle localization method that can be applied without using prior light detection and ranging (LiDAR) maps. Our method generates OSM descriptors by calculating the distances to buildings from a location in OpenStreetMap at a regular angle, and LiDAR descriptors by calculating the shortest distances to building points from the current location at a regular angle. Comparing the OSM descriptors and LiDAR descriptors yields a highly accurate vehicle localization result. Compared to methods that use prior LiDAR maps, our method presents two main advantages: (1) vehicle localization is not limited to only places with previously acquired LiDAR maps, and (2) our method is comparable to LiDAR map-based methods, and especially outperforms the other methods with respect to the top one candidate at KITTI dataset sequence 00.
