组合D-S证据理论在多传感器信息融合中的应用

Combined D-S Evidence Theory and Its Application to Multi-sensor Information Fusion

在多传感器的目标跟踪领域中,Dempster-Shafer证据理论及其组合方法得到了广泛的应用,但该理论本身也存在一些不足之处。针对D-S组合规则无法解决冲突证据这一情况,根据传感器的优先级不同,提出了采用组合的改进算法来取得合乎直观的合理结果。该算法简单,避免了复杂的数学运算,具有良好的工程应用背景。给定方法与传统D-S理论相比,提高了决策的准确性。

Dempster-Shafer evidence theory and rules of combination have found widespread application in dealing with Multi-sensor target tracking problem.However,it has some shortcomings.D-S evidence combination result cannot proceed if the evidence totally collides with each other.In addition,the combination result cannot keep accord with the real condition when evidence seriously conflicts.To solve this problem,according to the priority of sensors, this paper proposes a way by using combined D-S evidence theory to ...
