摘要:

在这项工作中,我们提出了一个快速占用地图构建方法的基础上的VDB数据结构。现有的基于对数几率的占用映射系统通常不能跟上现代传感器的高点密度和帧速率。因此,我们提出了一个高度优化的方法,基于现代数据结构来自计算机图形背景。多线程插入方案允许以前所未有的速度建立占用地图。多重优化允许在运行时间和地图质量之间进行可定制的权衡。我们首先证明了定量的一组消融研究和典型的基准集的方法的有效性,在我们实际上证明了系统使用足式机器人和无人机。

英文摘要:

In this work we present a fast occupancy map building approach based on the VDB datastructure. Existing log-odds based occupancy mapping systems are often not able to keep up with the high point densities and framerates of modern sensors. Therefore, we suggest a highly optimized approach based on a modern datastructure coming from a computer graphic background. A multithreaded insertion scheme allows occupancy map building at unprecedented speed. Multiple optimizations allow for a customizable tradeoff between runtime and map quality. We first demonstrate the effectiveness of the approach quantitatively on a set of ablation studies and typical benchmark sets, before we practically demonstrate the system using a legged robot and a UAV.
