Abstract

On January 20, 2024, Smart Lander for Investigating Moon (SLIM) landed on the Moon. Vision-Based Navigation (VBN) was used to estimate the position of the spacecraft accurately and autonomously during the descent phase, and it was successfully used in each of the seven regions. Obstacle detection was also performed 50 m above the lunar surface, successfully identifying safe points within the field of view of the navigation camera. As a result, SLIM was the first mission to realize pinpoint lunar landing technology with 100 m accuracy. This paper details the VBN operational concept and developed components, as well as the flight results of VBN in SLIM’s lunar landing operations.

基于视觉的导航和障碍物探测飞行实现了 SLIM 月球着陆

2024 年 1 月 20 日，月球探测智能着陆器（SLIM）登陆月球。在下降阶段，使用了基于视觉的导航（VBN）来自主准确地估计航天器的位置，并在七个区域中的每个区域都成功使用了该导航。此外，还在距月球表面 50 米处进行了障碍物探测，成功确定了导航相机视野内的安全点。因此，SLIM 是首次实现精确到 100 米的月球着陆技术的任务。本文详细介绍了 VBN 运行概念和开发的组件，以及 VBN 在 SLIM 月球着陆行动中的飞行结果。
