摘要
多传感器信息融合技术已获得了普遍的关注和广泛的应用,其理论和方法已成为智能信息处理的一个重要领域,证据理论是主要的技术之一。在目标识别系统中,为了获得可靠的识别结果需要考虑时间和空间的融合问题。从多传感器信息的时间域和空间域的融合出发,提出了在目标识别中多传感器信息的时空两级融合模型,以及基于证据理论的信息融合算法。仿真结果表明,该模型和算法具有方法简单、运算量小、可靠等优点,具有一定的理论意义和使用价值。
Multi-sensor information fusion technology is commonly concerned and variedly applied, and its theory and method becomes important area in intelligence information processing. D-S theory is one of the technologies. In target identification system,time and space fusion problem should be considered in order to get reliable recognized results. A model of time and space fusion was proposed based on multi-sensor information fusion in target identification, and then fusion algorithm was proposed based on D-S theory. Simulation results show that this model and algorithm have more advantages in simple method and lower computation and reliability, also this model and method is very efficient in theory and practice.
