提出了一种基于灰色关联分析的多传感器数据融合方法,计算多传感器测量数据的灰色关联矩阵,进行灰色优势分析,然后进行数据融合。此方法考虑了各传感器测量数据的精确度,而且删除了测量比较差或测量不到的数据。仿真结果表明,应用该方法可进一步提高多传感器的测量精度和可靠性,适用于多传感器的数据融合。

A fusion method of multi - sensor data is presented based on gray incidence analysis. The process of this method is to compute the gray incidence matrix of multi - sensor data, to analyze gray superior, to make the multi - data fusion. In the method the influence of each sensor's precision is taken into account and the precision lower data and the data can not be obtained by measurement are deleted. The simulation result indicates that the reliability and tracking precision of fusion system can be improved by using the method. It is suitable for the multi-sensor data fusion.
