多模态信息融合的一般功能模型设计——基于融合功能与信息层次

根据信息融合的功能要素,在分析了现有几种信息融合的一般功能模型的特点后,提出了基于融合功能与信息层次的多模态信息融合的一般功能模型(FH模型)。该模型综合了JDL模型、Omnibus模型和层次模型的优点,采取了JDL模型对信息融合功能的逻辑划分,指明了信息在系统中的流向,从而避免了开发基于JDL模型的信息融合系统时难以准确控制信息流向。此外,FH模型利用层次模型对Omnibus模型中的融合过程进行了更为细致的划分,同时加入了知识库和数据库管理体系,使信息融合的一般功能模型向更实用的方向迈进了一步,研究者可以将注意力更多地转向信息融合的结构模型和信息融合方法的设计,从而更有利于信息融合技术的研究。

New General Function Model of Multi-model Information Fusion System-Solution Based on Fusion Function and Information Hierarchy

A new general function model of multi-model information fusion system based on fusion function and information hierarchy(FH Model) is introduced according to the essentials of information fusion.Besides integrates the merits of JDL model,Omnibus model and hierarchy model,the FH model not only uses the logic partitions of JDL model,but also points out the flow of information in the system,making up the defect that the flow of information is difficult to be controlled exactly in information fusion system based on JDL model.At the same time,the FH model divides the fusion procedure of Omnibus model more particularly by using hierarchy model.Compared with other models,the FH model includes knowledge base and database management subsystems,thus the model is more practicable and researchers can pay more attention to the designs of information fusion methods and structure models.
