摘要

针对多传感器一致性测度的研究多集中于对某一时刻多传感器观测结果的判断

并未考虑时间序列的影响

导致某一时刻的一致性测度结果并不可信的问题

在传统的一致性测度基础上

采用一致性测度结果队列的中值作为测度结果的鲁棒估计

采用一致性测度结果队列的方差描述测度结果的稳定性

实现对一致性测度结果进行可信度评价

从而获得对传感器观测结果可靠性更好、可信度更高的评估。仿真实验表明

通过对多传感器观测数据的一致性测度结果进行可信度加权

可以显著提高一致性测度的鲁棒性

可以消除由于传感器性能不稳定带来的影响

有效识别出性能不稳定的传感器并将其剔除

为数据融合提供一致性传感器组。

Abstract

The research on multi-sensor consistency measure usually focuses on the judgment from multi-sensor observations at a specified moment without considering the influence of time series

which leads to an incredible consistency measure result. Following the traditional consistency measure methods

a new method with higher reliability and better accuracy for sensor observations is proposed. The mid-value in the queue of consistency measure results is regarded as the robust estimate

and the variance in the queue is used to describe the stability of the consistency measure result to process confidence evaluation on consistency measure result. Simulations show that the proposed method is able to significantly improve the robustness of consistency measure results and eliminate the effects of unstable sensor performance by credibility weighting of the multi-sensor observation data

thus to provide the consistency sensor group for fusion estimation.
