Decision-Making Level Fusion Based on DSmT for Multi-Sensor Life Detection Platform

Life detection based on a single type of information sources detection technology cannot completely meet the needs of the earthquake relief. First, we analyze the present situation of typical life detection technology, then the advantages of multi-sensor synergy detection technique are given. Second, we explained the platform structure and information fusion model. Finally, the fusion rule based on Dezert-Smarandache theory (DSmT) is used to achieve the decision level fusion. We present the results reached by the fusion with the conjunctive rule, the Dempster, the Yager and the DSmT. The experiments show that DSmT can get more comprehensive and more accurate information about the scene of rescue and survivors. The multi-sensor synergy life detection platform based on DSmT is more suitable for complex quake rescue environment. Copyright © 2014 IFSA Publishing, S. L.
