Embodiment Construction

[0050] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] In order to facilitate the understanding of the technical solution of the present invention, the principle of the generalized data fusion method of the present invention is firstly introduced before the examples are given.

[0052] On the basis of the existing data fusion results, the present invention proposes a method for solving the optimal fusion estimation problem of multiple sets of equations with a certain relationship or discrete data sets, that is, a generalized fusion solution method. It can combine multiple sets of solutions or multiple sets of discrete data into a set of optimal data sequence sets that can synthesize their respective advantages or strengths, that is, to find a set of optimal estimated value sequences for fusion data sequence sets. Traditional data fusion methods generally simply superimpose or merge...

Abstract

The invention discloses a generalized data fusion method. The method includes: constructing a generalized fusion solving problem model; solving a status calculating equation to obtain a status calculated value; establishing a relative status quantity recurrent equation to obtain an recursive estimated value (as shown in the description); combining a direct solution status value and a status estimated value (as shown in the description) of t n epoch to obtain a status optimal solution value (as shown in the description); and repeatedly using iterative solution to obtain a set of optimal solution. According to the method, a predictive estimated value obtained by recurrence of low order state quantity is directly fused to a high order state solution value, when the measurement accuracy of low order state quantity is higher, through successive mutual calibration, the data is synthesized, the accuracy of high order state quantity synthesis value is obviously improved, and the more accurate expression or estimation of target state quantity is obtained. The invention can be applied to data processing of a sensor, can synthesize multi-band information of a single sensor or information provided by different type sensors, so that possible contradictions among multiple sensors can be eliminated, and the use efficiency of data is improved.

Description

technical field [0001] The invention relates to the technical field of data fusion, in particular to a novel generalized data fusion method, which is used to improve the performance of data and increase the validity of data. Background technique [0002] Data fusion technology originated from the sonar signal processing system funded by the US Department of Defense in 1973, and its concept appeared in some literatures in the 1970s. After the United States successfully developed the sonar signal processing system, in the 1980s, in order to meet the needs of combat in the military field, multi-sensor data fusion MSDF (Multi-sensor Data Fusion) technology came into being. In 1988, the United States listed the data fusion technology in the C3I (Command, Control, Communication and Intelligence) system as one of the twenty key technologies developed by the Ministry of Defense. [0003] The key to the realization of information fusion technology lies in the fusion algorithm. For ...
