【摘要】 介绍多传感器信息的决策融合原理及其常用方法,重点分析了基于目标检测理论的决策融合法和基于Dempster Shafer(D S)证据理论的决策融合法,并分别以融合实例讨论了它们在漏磁和涡流无损检测中的应用。多传感器信息的决策融合法有效提高了多源信息的利用程度,具有较高的可靠性和稳健性。

【Abstract】 The principle and main methods of multi-sensor decision fusion technology were presented. The Neyman-Pearson (N-P) test-based decision fusion method and Dempster-Shafer (D-S) evidence theory-based decision fusion method were analyzed in detail. Examples for its application to magnetic flux leakage testing and eddy current testing were also given and the results showed that multi-sensor decision fusion technology made full use of information and was high in reliability and robustness.
