| 摘 要： | 针对多传感器的加权融合算法,提出了一种基于支撑裕的算法。先构造支撑裕函数,通过参与融合的数据生成支撑裕矩阵,同时将一致性因素引入到支撑裕矩阵中并代替原有的恒定因素‘1’,为可靠的传感器赋予较多的权重影响。通过改进的支撑裕矩阵度量各传感器的综合支撑裕度,最终将综合影响表现在各数据所占的权重中,形成一种新型加权融合算法。在实例分析比较中可看出,相比已有的算法,该算法在精度和抗干扰能力上都有所提高。

| Abstract: | Focusing on multi-sensor weight data fusion algorithm,an algorithm based on support degree is proposed.Firstly,a support degree function is defined to build a support degree matrix with the data to be fused.The consensus factor of sensors is considered to replace the invariable factor ‘1’ during the time the support degree matrix is built,thus the reliable sensor will get more weight.Then,the synthesis support degree of data from various sensors is measured through the improved support degree matrix.Finally,the reasonable choice of weight is realized by making use of the synthesis support degree of data and a new kind of weight data fusion algorithm is formed.The applied example proves that the proposed method can reach higher fusion precision and better restraint ability against disturbance than existing methods. |
