Abstract:

For the fine-grained ship target classification in multi-payload collaborative detection task, considering the various revisit time of payloads, a method based on entropy weight and credibility model for fine grained classification of ship targets is proposed. With the support of historical information, the uncertainty of multiple electronic/imaging detection payloads are evaluated through entropy weight.Then, a certainty factor model is established based on weighted synthesis rules. The proposed method solves the interruption of reasoning issues caused by intersection of detection windows via combininng regional historical situation, achieving decision-level cross-modal information fusion. In the fine-grained classification task involving six categories of ship targets, the accuracy of the proposed method achieves 91%, demonstrating satisfactory accuracy and robustness.

Key words: information fusion, fine-grained classification, eletronic detection, imaging detection
