Abstract:

Marine narigation radar and electronic navigational chart (ENC) are important navigation instruments. The fusion of radar images and electronic navigational chart data can give more abundant navigation and collision avoidance information. Therefore, this paper proposes a data fusion algorithm based on deep learning to extract robust features from radar images. At first the ability of deep learning is exploited to perform target detection for the identification of marine radar targets. Then, the image processing is performed on the identified targets to determine the reference points for consistent data fusion of ENC and marine radar information. Finally, an affine transformation-fusion algorithm is built to merge the marine radar and electronic chart data according to the determined reference points. The proposed fusion algorithn is verified through simulations using ENC data and marine radar images from real ships in narrow waters in a continuous period. The results show a suitable edge matching performance of the shoreline and real-time applicability. The algorithm is more robust than the simple pixel-level image fusion, and it realizes the feature level fusion of ENC and radar images.
