LIU Shuo, GE Yuan, LI Yuanyuan, et al. Recognition algorithm of unmanned ship at sea based on improved SSD[J]. 2021, (2): 120-123. DOI: 10.13873/J.1000-9787(2021)02-0120-04.
Aiming at the problem of inaccurate ship recognition and low recognition precision in the images acquired by vision system of unmanned ship navigating at sea
an unmanned ship recognition method based on improved single shot multibox detector( SSD) is proposed. This method improves the traditional SSD network by adding L2 regularization to the seventh layer
which makes the parameters of each convolution layer of SSD more balanced
reduces the sensitivity of the model to local features
and improves the confidence of ship recognition.The experimental results show that the method has better recognition effect and the model based on improved SSD training has better generalization ability.
