Aiming at the problems of target loss and poor real-time performance in ship detection at sea, a target detection method based on improved YOLOv4-Tiny network was proposed to realize real-time detection of ship video. Firstly, an output prediction scale of 52×52 is added to the network structure to improve the detection ability of small targets on ships. Secondly, based on the improved model structure and self-established data set, the priori anchor frame was redesigned. Finally, the mish activation function is used to improve the model performance of YOLOv4-Tiny. The experimental results show that the improved YOLOv4-Tiny algorithm not only retains the great advantage of fast detection speed, but also significantly improves the detection accuracy. It can realize real-time high-precision detection of ship video, which is of great significance for maritime safety law enforcement and supervision.
