Before using D-S(Dempster-Shafer) theory for evidence fusion,the extent of the conflict among evidences should be determined. Aiming at this problem,this paper proposes a conflict measure and correction method based on trust degree and false degree. It calculates both trust degree and false degree of each evidence and sorts them respectively. The evidence with smaller trust degree and larger false degree is called high conflict evidence and done weighted correction.Then the Dempster combination rule is used...
