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检测飞行导致 SLIM 月球着陆


2024 年 1 月 20 日，用于探月的智能着陆器 （SLIM） 登陆月球。基于视觉的导航 （VBN） 用于在下降阶段准确自主地估计航天器的位置，并成功用于七个区域中的每个区域。还在月球表面上方 50 m 处进行了障碍物检测，成功确定了导航相机视野内的安全点。因此，SLIM 是第一个实现精度为 100 米的精确月球着陆技术的任务。本文详细介绍了 VBN 操作概念和开发的组件，以及 VBN 在 LIM 月球着陆操作中的飞行结果。
