Day Seven: Sensor Fusion TL/DR Sensor fusion is a generic term for techniques that address the issue of combining multiple noisy estimates of state in an optimal fashion. There’s a straight forward view of it as the gain on a Kalman–Bucy filter, and an even simpler interpretation under the central limit theorem. A Primer on Stochastic Control Control theory is...
