Aimed at the information fusion in the case of multi-source information conflict and,combining game theory with information fusion together,a multi-source information fusion model based on information game was presented.With the guidance of game theory,the players,strategy,payoff were taken as the basic factors in this model.The target identification or situation estimate was taken as its kernel function.And the conflict and cooperation in the fusion were taken as mutual game of multi-source information with different strategies.Aimed at situation estimate or target identification in uncertain conditions,the expressions and solving methods of information game based on Bayesian networks were put forward.In an application,the model and algorithm of information fusion based on information game was applied to vehicle identification in electronic toll collection system.The test result indicated that information fusion based on information game was superior to the traditional information fusion,and could improve identification result remarkably.
