Abstract: Disclosed is a ship detection and tracking method and device, the method comprises: pre-training a yolov5s network model with a first preset number of high-speed moving object datasets to obtain an initial ship detection model; adding a preset attention mechanism to the initial ship detection model to obtain a transitional ship detection model; inputting a second preset number of annotated ship datasets into the initial ship detection model with the preset attention mechanism for training to obtain a target ship detection model; inputting an original ship video frame into the target ship detection model, and outputting the position information of the ship to be tracked; performing ship video image tracking on the ship to be tracked according to the position information. This disclosure performs pre-training, which only requires a small amount of annotated ship data to determine the target ship detection model, achieving video image tracking of the target ship.

Abstract: A squid-type marine oil containment device includes a track and four oil containment booms. A robotic arm is provided in an elliptic area formed by the track. Sliders are provided on the track. Ends of oil containment booms slide along the track through sliders. Each oil containment boom includes an oil suction pipe, propellers and a plastic separating layer. A middle of the oil suction pipe forms an oil channel. Booster pumps are spacedly provided inside the oil suction pipe and are respectively connected to a hose. Pairs of propellers are spacedly provided at a lower end of the oil suction pipe. Oil suction holes are provided on the oil suction pipe. The plastic separating layer is provided under the oil suction holes. A counterweight is provided at a bottom of the oil containment boom. The invention further provides a method of containing oil using the device.
