Improvement of D-S Theory of Evidence in Multi-sensor Information Fusion System
Jianping Lv · Modern Electronic Technique · 2005
This paper elaborates the multisensor information principle about DempsterShafer theory of evidence. It′s an useful method to deal with uncertain problems. But its application is limited by the shortcomings of the combination rules. And an improved combination method is put forward according to shortage of the formula through in depth analysis. Thus we can′t only make up conflicted evidence like this with different online weights, but also carry out adaptive weighting association according to the amount of information that an evidence includes. Thus improving the combination criteria of DS theory of evidence as well as increasing its fusion capability, and some examples have been done to demonstrate that the new method is efficient.
