摘要
作为一种重要的处理不确定性问题的方法,D-S证据推理理论目前已经广泛应用于各种数据融合系统中。详细阐述了D-S证据理论的相关理论和证据组合原理;针对D-S证据理论存在的缺陷和不足,介绍了一种改进的证据组合方法;通过实例证明,该改进方法能够用于组合冲突比较大的多个证据,并提高融合的性能和可靠性。
As one of the most important data fusion methods used for dealing with uncertainty problems,the D-S evidence reasoning has been applied to lots of data fusion systems.In this paper, the evidence combination principles of D-S evidence theory are repre-sented in detail firstly. In view of the deficiency of D-S method, one of improved evidence combination method is introduced. A giv-en practical example demonstrates that the improved method can be applied to dominating multi evidences with great confliction, and the performance and reliability of fusion can also be improved.
