| Abstract: |
| The multi-source information fusion technology contains three levels: the data level, the feature level and the decision level. In the application of ocean detection, current methods have some difficult problems of information acquisition, fusion quality and target recognition. This paper proposes the solution ideas of systematic detection, distributed fusion and using prior knowledge. The systematic detection can obtain the original information comprehensively. Distributed fusion reduces the computational complexity and information loss at the same time. Using prior knowledge improves the accuracy of target recognition in the decision-level fusion. In addition, This paper puts forward the development direction of information fusion technology in the future, such as the construction of detection systems and prior knowledge bases and the optimization of intelligent algorithms and models. |
