Juan-Hua Liu · Journal of Xi'an University of Technology · 2012
In order to solve the true value estimation problems of unrepeatable measurement physical quantities,a kind of data fusion is put forward by the author.This model adopts multiple sensors to measure simultaneously the same physical quantities,wavelet transform of measure results of each sensor has been performed,then in different wavelet scale domain measurement value of each sensor has been weighted and averaged on multi-scale,finally,the real value estimation of the physical quantity to be measured can be obtained by reverse wavelet transform.This paper is an analysis and summary of the multi-scale data fusion model proposed by the author,including reviews of the related research fields,and on the basis of introducing this model,the theorem concerning data fusion and the important derivation and conclusions are given in this paper.
