Sensor Fusion
Formal
Sensor fusion is combining of sensory data or data derived from disparate sources such that the resulting information has less uncertainty than would be possible when these sources were used individually.
Practical
Sensor fusion is combining of sensory data or data derived from disparate sources such that the resulting information has less uncertainty than would be possible when these sources were used individually. For example, because of the quantity of sensors, a NASA un-crewed vehicle on Mars requires sensor fusion to detect if there has been a failure. Sensor fusion is also known as (multi-sensor) Data fusion and is a subset of information fusion.
