What is sensor fusion?

  • A.Combining several sensors' readings into one estimate of state
  • B.Connecting several sensors to a single processing channel
  • C.Replacing several sensors with one of higher accuracy
  • D.Switching between sensors according to which is the most reliable

Answer: A

Fusion combines complementary and redundant measurements, weighting each by its reliability, to give a better estimate than any one sensor could provide, and a Kalman filter is the classical implementation. Physical connection, sensor replacement and switching are different arrangements, though selection is a crude form of fusion. Using the disagreement between sensors to estimate their reliability, as well as the state, is what makes a fusion algorithm more than an averager.
