Abstract: Aiming at the recognition problem of multi-targets which have many characteristic indexes,a new fusion method for the fuzzy multi-sensor data based on Vague sets is proposed.The method defines the entropy weight to objectively obtain the weights of characteristic indexes and transforms the characteristic values of objects into Vague value representation.The method of object recognition is given according to the distance between Vague values.The example of parts recognition proves that the method is both effective and practicable.
