HN comment orderCouple of years ago I blogged about how it was developed for the Apollo program [1] and then I wrote an implementation of different variations of it in Go [2]. [1] https://cybernetist.com/2019/01/13/apollo-kalman-filter-and-... [2] https://github.com/milosgajdos/go-estimate
I'll be shameless and point you to my book on Kalman filtering which I wrote in IPython Notebook, which allows you to experiment within your browser. https://github.com/rlabbe/Kalman-and-Bayesian-Filters-in-Pyt...
Kalman filters are wonderful things and great for keeping track of where other things are in relation to yourself. But for localizing my robot I'd generally use a Particle Filter[1] instead to allow me to represent multiple hypothesis about where I am. For example if I see a doorway I know I'm going to be by one of the doorways on the corridor but I won't be able to tell which one without further observation. But if there's a source…
For anyone who read this blog post and thought "Wow that's interesting, but I don't understand half of this. I need a whole youtube series to explain this to me." Well we're in luck. https://www.youtube.com/watch?v=CaCcOwJPytQ. It's a great set of 55 video lectures on Kalman filtering. (I'm only on number 5 but so far they've been great)
