| 摘 要： | D-S(Dempster-Shafer)证据理论作为不确定性推理的有效工具,广泛应用于多传感器信息融合领域1]。而D-S证据理论在证据高度冲突时,应用D-S合成规则可能得到有悖常理的结论。针对这一问题,从分析引起D-S冲突问题的原因入手,引入决策距离测量概念求取高度支持的最大传感器连接组,剔除互不支持的传感器信息,在此基础上应用D-S证据合成规则进行多传感器信息融合。实例表明,该方法能够克服D-S冲突问题,保证信息融合结果的准确度。

| Abstract: | As an effective tool for uncertainty reasoning,D-S evidence theory is widely applied to the multi-sensor information fusion field.However,when there are highly conflicting evidences for D-S evidence theory,the application of D-S combination rule may draw out counterintuitive conclusions.To solve the problem,the paper starts from analyzing the reasons for D-S conflict,then introduce decision distance measurement concept to compute for highly supported maximum sensor connection groups,eliminating sensor infor... |
