This article provides new ideas for promoting the application of the target detection technology of the ship.

Ship target testing is the cornerstone of intelligent maritime applications such as waters monitoring, port traffic statistics, ship identity identification, and behavioral analysis and evidence collection. With the advancement of the construction of my country's marine powers, the rapid development of smart shipping and smart marine projects, and effective detection and identification of effective ship target targets through maritime monitoring videos to ensure the safety of shipping and marine engineering. For the target detection tasks based on maritime monitoring videos, reviewing the target detection data set and performance evaluation indicators, traditional machine learning and deep learning methods based on convolutional neural networks, etc. , Analyze the diversity of the target scale of the ship's target detection task in the marine environment, the diversity of the ship category, the complexity of the marine weather, the dynamics of the water surface, the motion of the camera, and the low quality of the image Difficulties, and through experimental verification, proposed the optimization method of ship target detection in the aspects of multi -scale characteristics, wide data, and reduced energy consumption. The adaptability of the granularity, the consistency of the marking, and the easy expansion of the data set should strengthen the study of the model structure of the multi -scale target (especially the small target) detection. The application of ship target detection technology provides new ideas.

Human beings are inseparable from marine activities as carriers and tools. In a specific environment, automatic testing of ship targets is a key technology in the fields of port traffic statistics and collision avoidance. With the development of marine detection technology, human development and utilization of the ocean have moved from the sea to the bottom of the sea, especially in the early 21st century, long -term observation of network network networking technology. The Underwater Observation Network can put a series of marine observation instruments to the bottom of the sea. It becomes an open marine comprehensive observation system through the interconnection of land -based information processing equipment through the underwater light cable. The information transmission capacity can realize the large -scale, all -weather, comprehensive, long -term, continuous and real -time observation observation of the deep -sea, the underwater interface to the sea water body and the sea surface. The Underwater Observation Network is the third earth scientific observation platform established by human beings after the ground and the sea observation and the remote sensing remote sensing in the air, which will become the main way for future marine detection and research. However, a large number of instruments and equipment facing the bottom of the sea are the destruction of human fishery activities to the underwater facilities, especially in the East China Sea with frequent fishery activities in my country. According to reports, 90% of my country's international sea light cable failure was affected by the damage of human fishery activities (Ye Yincan et al., 2015). Once the underwater cable and submarine equipment are damaged or broken, the entire engineering power and communication are broken during the system, and the maintenance cycle is long and the maintenance is difficult, which will bring huge losses.

In order to prevent the ship's anchor and fishing near the sea underwater facilities, the currently adopted the target of the sea -surface ship for the automatic identification system (AIS) position monitoring, but this monitoring is deliberately smuggled by those deliberately closed AIS to smuggle AIS It is difficult to monitor the catcher, and it is difficult to obtain evidence and law enforcement on ships that have undergone damage. Therefore, the buoyant of the video sensing camera is installed near the underwater facility, and the timely ship target recognition of the video image is developed, which has become a very effective means to monitor peripheral ships and protect the underwater engineering facilities. With the advancement of the construction of my country's marine powers, the rapid development of smart shipping and intelligent marine projects, and the demand for shipping and marine engineering safety through maritime monitoring videos to ensure the safety of shipping and marine engineering through maritime monitoring videos. For the target detection of ship targets based on maritime monitoring videos, the research status of domestic and foreign research on the detection method is reviewed, and the technical difficulties in the target detection task of the ship's target. From the diversity of the target scale, the performance of the model, and the reduction of the model of the model, and the reduction of the model's requirements for the amount of equipment computing, and conducted an experimental assessment of the corresponding model, providing ideas for promoting the application of ship target detection technology.
