- 视觉SLAM开源算法ORB-SLAM3 原理与代码解析
ORB-SLAM 3的基本流程和此前的ORB版本没有显著的改变，只是也增加了部分新特性。 基于词袋模型的关键帧数据和之前差不多，每一个关键帧均会被存入数据库用于回环检测。
- Let a group G act on a set $X$, and suppose that $x,y \\in X$ lie in . . .
I think you showed $\;g^ {-1}G_yg\subset G_x\;$ and not what you wrote in the last line (not that it matters, of course why? ) Also, how did that $\;a\;$ at the end of the line before the last one (of calculations) come into being? I think you meant $\;x\;$ there

- How did Le Verrier calculate Neptunes position?
Edit 2: since the work of Le Verrier seems beyond the scope of a stackexchange question, is it possible to explain the general approach? Quote from the article above: Jean-Baptiste Biot attempted to explain Le Verrier's methods in six papers in *Journal des Savants (October 1846, pp 577–596; November 1846, pp 641–664; December 1846, pp 750–768; January 1847, pp 18–35; February 1847
- 如何评价Orbstack（在Mac上低开销地运行容器和Linux）？ - 知乎
orb 命令还提供了其他一些特性，比如可以在虚拟机中 push 或 pull 来传输文件。 目前的一些局限 OrbStack 虚拟的 Linux 是不支持 GUI 的，不过这也不妨碍，我想大部分开发应该只会使用命令行去管理 Linux 运行环境吧。
- Proofs that the degree of an irrep divides the order of a group
It seems plausible that the finite set $Orb (v)$ could now be a basis of $V$ and thus prove the result, but I was curious whether someone with more rep theory experience had an example to contradict this before I try to proceed

ORB_SLAM2： 视觉SLAM领域中特征点法的代表作，也是首个同时适用于单目、双目和RGB-D相机的开源SLAM方案。代码主要分为三个线程：前端实时定位跟踪、后端优化建图与回环检测。整套代码几乎涉及到了视觉SLAM系统的方方面面：从单目系统初始化、特征提取匹配，到LocalBA、GlobalBA的优化设计，到关键帧
