论文摘要
由于长期机器人操作中的地图尺寸的增长，现有的同时定位和映射方法的可伸缩性受到限制。此外，处理此类地图进行本地化和计划任务会导致船上所需的计算资源增加。为了解决长期操作中记忆消耗的问题，我们开发了一种基于神经场隐式图表示的新型实时SLAM算法Meslam。它结合了提出的全球映射策略，包括神经网络分布和区域跟踪，以及外部进程系统。结果，该算法能够有效地训练代表不同地图区域的多个网络，并在大规模环境中准确地训练姿势。实验结果表明，所提出的方法的准确性与最新方法（平均为6.6 cm的TUM RGB-D序列）相媲美，并且优于基线，IMAP $^*$。此外，提议的SLAM方法提供了最紧凑的地图，没有细节变形（1.9 MB，可在最先进的大满贯方法中存储57 m $^3 $）。
Existing Simultaneous Localization and Mapping (SLAM) approaches are limited in their scalability due to growing map size in long-term robot operation. Moreover, processing such maps for localization and planning tasks leads to the increased computational resources required onboard. To address the problem of memory consumption in long-term operation, we develop a novel real-time SLAM algorithm, MeSLAM, that is based on neural field implicit map representation. It combines the proposed global mapping strategy, including neural networks distribution and region tracking, with an external odometry system. As a result, the algorithm is able to efficiently train multiple networks representing different map regions and track poses accurately in large-scale environments. Experimental results show that the accuracy of the proposed approach is comparable to the state-of-the-art methods (on average, 6.6 cm on TUM RGB-D sequences) and outperforms the baseline, iMAP$^*$. Moreover, the proposed SLAM approach provides the most compact-sized maps without details distortion (1.9 MB to store 57 m$^3$) among the state-of-the-art SLAM approaches.
