Abstract EN
Ship detection is one of the most important research contents of ship intelligent navigation and monitoring.
As a supplement to classical navigational equipment such as radar and the Automatic Identification System (AIS), target detection based on computer vision and deep learning has become a new important method.
A target detector called YOLOv3 has the advantages of detection speed and accuracy and meets the real-time requirements for ship detection.
However, YOLOv3 has a large number of backbone network parameters and requires high hardware performance, which is not conducive to the popularization of applications.
On the basis of YOLOv3, this paper proposes a lightweight ship detection model (LSDM) in which the backbone network is improved by using dense connection inspired from DenseNet, and the feature pyramid networks are improved by using spatial separation convolution to replace normal convolution.
The two improvements reduce parameters and optimize the network structure greatly.
The experimental results show that, with only one-third of parameters of YOLOv3, the LSDM has higher accuracy and speed for ship detection.
In addition, the LSDM is simplified further by reducing the number of densely connected units to form a model called LSDM-tiny.
The experimental results show that, LSDM-tiny has similar detection speed with YOLOv3-tiny, but has a lot higher accuracy.
