一种基于局部冲突再分配的改进DSmT方法
An Improved DSmT Algorithm Based on Local Conflict Redistribution
摘要
Abstract
In the light of the disadvantages of large amounts of calculation and slow convergence speed in DSmT combination rule,an improved DSmT algorithm based on local conflict redistribution is proposed in this paper.Firstly,the inconsistent factor and conflict distance between every two pieces of evidence are used to measure the conflict degree among pieces of evidence,and the calculation method for the credibility of each focal element generating the contradictory information under the recognition framework is presented. Secondly,based on the principle of the redistribution of conflict information, local conflict information is reassigned to the related subset and union according to their respective proportion. Finally,a numerical example is used to analyze the data,at the same time,a simulation experiment is implemented under the background of multi-sensor multi-target recognition system. Data and experimental results verify the feasibility and effectiveness of the improved DSmT algorithm presented in this paper.关键词
