摘要:

由于它们的普遍性和长期稳定性,杆状物体非常适合作为城市环境中车辆定位的地标。在这项工作中,我们提出了一个完整的映射和长期定位系统的基础上从3-D激光雷达数据提取的极点地标。我们的方法采用了一种新的极点检测器,映射模块和在线定位模块,其中每一个都有详细描述,我们在www.github.com/acschaefer/polex上提供了一个开源实现。在广泛的实验中,我们证明了我们的方法在长期可靠性和准确性方面提高了最先进的水平:首先,我们通过任务系统在15个月的时间内根据初始地图在城市地区定位移动机器人来证明可靠性,面对不断变化的路线,不同的天气条件,季节变化和建筑工地。其次,我们表明,所提出的方法显然优于最近发表的方法在准确性方面。

英文摘要:

Due to their ubiquity and long-term stability, pole-like objects are well suited to serve as landmarks for vehicle localization in urban environments. In this work, we present a complete mapping and long-term localization system based on pole landmarks extracted from 3-D lidar data. Our approach features a novel pole detector, a mapping module, and an online localization module, each of which are described in detail, and for which we provide an open-source implementation at www.github.com/acschaefer/polex. In extensive experiments, we demonstrate that our method improves on the state of the art with respect to long-term reliability and accuracy: First, we prove reliability by tasking the system with localizing a mobile robot over the course of 15~months in an urban area based on an initial map, confronting it with constantly varying routes, differing weather conditions, seasonal changes, and construction sites. Second, we show that the proposed approach clearly outperforms a recently published method in terms of accuracy.
