1. An object recognizing apparatus for recognizing an object based on signals received from a plurality of sensors, comprising: an existence probability calculating unit configured to calculate each existence probability of the object to each sensor based on a normal distribution centering on an output value of each sensor; an existence probability correcting unit configured to calculate each corrected existence probability by correcting said each existence probability with a recognizing rate of each sensor; and a fusion existence probability calculating unit configured to calculate a fusion existence probability of the object by fusing said each corrected existence probability.
