An Improved Method of D-S Evidential Reasoning
Wang Junjie · Acta Simulata Systematica Sinica · 2004
D-S evidential reasoning is a usual method in multi-sensor fusion, but it can抰 determine the reliability of the evidence. The paper firstly calculates the local decision on the basis of the measurement, on which the support matrix is based. Then the eigenvector is gained from the support matrix, and it is the reliability vector of the system. The paper improves the D-S evidential reasoning by giving a weight to evidence that equals to the evidence抯 reliability. At last, an example is given out. It proves that the method described above is valid when some evidences are false or far from the real value.
