Covariance... I don't get it...
Hi folks,
as someone who has never had the opportunity to participate in a calculus of probability course I don't have the faintest clue of how covariance
works. But it seems that I need to in order to get navigation
, SLAM
and actual driving to run optimally.
Assuming a differential robot with wheel encoders (decoupled from the driveshafts to avoid slippage) and a laser scanner, why, where, how... covariance
... and... well, actually... I basically don't even know where to start asking.
Is there anybody out there who can explain covariance
to me like I'm five? I'd be deeply grateful and I apologize for a not that well couched question.
Cheers, Hendrik

maybe wikipedia? http://en.wikipedia.org/wiki/Covariance_matrix

Wikipedia is unsuitable to help understanding mathematical problems if you lack even the basics. So, yes, I've tried and I've failed to wrap my head around it.
