EECI09: Distributed estimation and sensor fusion
|Prev: Cooperative control||Course home||Next: Information systems|
In this lecture, we introduce the basics of distributed estimation. We consider both static sensor fusion and distributed Kalman filtering. We discuss some existing algorithms, and point out some open problems.

Rao, Durrant-Whyte and Sheen, "A Fully Decentralized Multi-Sensor System For Tracking and Surveillance", International Journal of Robotics Research, 1993. This papers makes use of the information form of the Kalman filter to formulate a Kalman filter with no central fusion node but full connectivity.
