Abstract

The invention, which belongs to the technical field of multi-sensor information fusion, discloses an evidence-synthesis-based information-fusion target recognition method. A plurality of sensors are used for carrying out attribute information collection on a to-be-identified target and a feature attribute is extracted from the collected attribute information; data having the feature attribute aredivided into training data and testing data, wherein the training data are used for constructing a neural network model and the testing data are used for obtaining a basic probability assignment value; and then evidences are synthesized based on an improved evidence synthesis method and the synthesized result is used as the target recognition basis. According to the invention, the basic probability assignment values of evidences are obtained accurately and a synthesis problem of high-conflict evidences is solved. The basic probability assignment values of evidences are obtained by using the neural network and the neural network has the high nonlinear mapping capability and is capable of mapping the intrinsic relationship between the target feature data, so that the accuracy of the basic probability assignment values is ensured, the conformance to the real scene is realized, and the practical significance is good.

Description

technical field [0001] The invention belongs to the technical field of multi-sensor information fusion, and in particular relates to an information fusion target recognition method based on evidence synthesis. Background technique [0002] Multi-sensor Information Fusion (MIF), also known as information fusion, is an automatic information comprehensive processing technology formed and developed in the 1980s. With the development of science and technology such as communication technology, electronic technology, and computer technology, the forms of information are complex and diverse, the content of information is all-encompassing, and the amount of information is unprecedentedly vast. The information obtained by a single sensor is always incomplete, reflecting the information of a certain aspect of the target to be measured, and cannot grasp the overall content. Target recognition is one of the main application fields of multi-sensor information fusion technology. In the p...
