Abstract:

Spaceborne synthetic aperture radar (SAR) and automatic identification system (AIS) can obtain the information of the detected target. And the association and fusion of the information obtained from the two sensors is beneficial to realize efficient maritime reconnaissance and surveillance. Due to the heterogeneity gas between different data, traditional methods mostly rely on artificial features to establish correlation between SAR images and AIS information, but these methods have disadvantages of poor accuracy and low efficiency. In this paper, the association method between SAR images and AIS information based on depth feature fusion is proposed. According to the characteristics of the two modal data, the corresponding feature learning network is designed respectively to obtain the unimodal feature representation, and the feature information of different modals is further fused to enhance the semantic correlation of cross-modal information. Then, the association learning between cross-modal features is carried out by the designed association learning objective function. Verification on the constructed dataset shows that the proposed method can achieve high correlation accuracy and strong adaptability, and the effectiveness of the proposed dataset and method is verified.

Key words: multi-source data association, deep learning, remote sensing image, cross-modal retrieval
