前言
1. 本文由知乎作者小吴同学同步发布于https://zhuanlan.zhihu.com/p/115599978/并持续更新。
2. 本文简单将各种开源视觉SLAM方案分为以下 7 类(固然有不少文章无法恰当分类)：
·Geometric SLAM
·Semantic / Learning SLAM
·Multi-Landmarks / Object SLAM
·VIO / VISLAM
·Dynamic SLAM
·Mapping
·Optimization
3. 由于本人自 2019 年 3 月开始整理，所以以下的代码除了经典的框架之外基本都集中在 19-20 年；此外个人比较关注 VO、物体级 SLAM 和多路标 SLAM，所以以下内容收集的也不完整，无法涵盖视觉SLAM 的所有研究，仅作参考。
一、Geometric SLAM(20 项)

三、Multi-Landmarks / Object SLAM(12 项)

七、Optimization(6 项)
个人感觉优化可能是 SLAM 中最难的一部分了吧 +_+ ，我们一般都是直接用现成的因子图、图优化方案，要创新可不容易，分享山川小哥d的入坑指南https://zhuanlan.zhihu.com/p/53972892。
