Visual-SLAM Developer Roadmap - 2022

Roadmap to becoming a Visual-SLAM developer in 2022, inspired by web-developer-roadmap and game-developer-roadmap.

Visual-SLAM is a special case of 'Simultaneous Localization and Mapping', which you use a camera device to gather exteroceptive sensory data.

Below there is a set of charts demonstrating the topics you need to understand in Visual-SLAM, from an absolute beginner difficulty to getting ready to become a Visual-SLAM engineer / researcher.


Visual-SLAM is often portrayed as a rather difficult topic - many think good C++ programming skills and deep understanding of mathematics is necessary.

On the other hand, there are not many courses provided for beginners, especially in non-English languages.

I made these charts to share my thoughts and experience on studying Visual-SLAM, and hopefully the beginner learners can get a grasp of where to start from.


Purpose of these Roadmaps

The purpose of these roadmaps is to give you an idea about the general overview of Visual-SLAM, and to guide you if you are confused about where to start from.

Note to Beginners

Acknowledge that SLAM has a relatively high entry barrier - it's not because of the requirement of undertanding difficult mathematics, but the requirement of equipping yourself with various types of skills. Don't feel overwhelmed - you don't need to learn everything if you are just getting started. Instead, enjoy the journey itself and progress topic by topic. The result will be very rewarding.

🚦 Wrap Up

If you think any of the roadmaps can be improved, please do open a PR with any updates and submit any issues. Also, I will continue to improve this, so you might want to watch/star this repository to revisit.

Also, check out my GitHub and blog 😺

🙌 Contribution

The roadmaps are built using Balsamiq. Project file can be found at /project-files directory. To modify any of the roadmaps, open Balsamiq, click Project > Import > Mockup JSON, it will open the roadmap for you, update it, upload and update the images in readme and create a PR.
