虽然DS方法已广泛应用于各种数据融合系统中,但是由于DS方法的核心—Dempster合成规则的计算复杂性,使得其算法实现成为一个难题。本文介绍了Dempster-Shafer证据理论的发展简况,讨论了DS方法的理论模型及其与数据融合模型的关系,并着重分析了它的一些有代表性的实现途径,最后从数据融合角度对DS方法进行了简要的述评。 Although the DS method has been widely used in a variety of data fusion systems, its computational complexity becomes a challenge due to the computational complexity of Dempster synthesis rules, the core of DS methods. This paper introduces the development of evidence theory of Dempster-Shafer, discusses the theoretical model of DS method and its relationship with data fusion model, and emphatically analyzes some representative ways of its implementation. Finally, from the perspective of data fusion, A brief review was made.
