Patent ID: 7542825

Claim:
A sensor fusion system comprising: a plurality of detecting units, each of which detects a data value of a given data kind; a plurality of probability distribution computing units, each of which computes a probability distribution of the data value detected by a corresponding detecting unit included in the plurality of detecting units, wherein the probability distribution of the data value indicates likelihood to a true value of the given data kind, and then outputs the computed probability distribution; and a synthetic determining unit that estimates a most likely data value of the given data kind based on the probability distributions outputted from the plurality of probability distribution computing units, wherein each of the plurality of probability distribution computing units comprises a probability distribution converting unit, which converts the data value detected by the corresponding detecting unit into the probability distribution by using distribution data statistically aggregated from data values detected in past times by the corresponding detecting unit; and the probability distribution computed by each of the probability distribution computing units is represented as a sum of a Gaussian distribution and a uniform distribution.
