基于近邻量测认知信息的多传感器融合估计

Multi-sensor Fusion Estimation Based on Adjacent Measurement Cognitive Information

在构建传感器模糊量测认知偏差的基础上,提出一种新的多传感器融合估计方法。运用相邻量测样本均值和协方差度量传感器可靠性,确保融合权重分配的客观性和灵敏性。实验结果表明,与基于均值融合算法和支持度融合算法相比,使用该方法得到的融合权值分配方式更加合理,可进一步提高估计精度。

On the basis of constructing the fuzzy measurement cognitive bias, a novel independent quota fusion algorithm for the multi-sensor data is proposed. And the given sensor＇s reliability can be obtained by using mean value and covariance value of the adjacent information, which can ensure the objectivity and sensitivity for the fusion weight assignment. Experimental result shows that compared with the mean and support degree based data fusion techniques, the more reasonable fusion weight assignment can improve the fusion precision further by the proposed method.
