Problems solved by technology

[0003] Traditional night ship detection methods can be divided into three categories: firstly, use infrared cameras to adapt to nighttime, foggy weather and other weather conditions for night ship detection, but infrared cameras are expensive and not widely used; secondly, synthetic aperture Radar SAR performs all-weather ship detection, but due to the high energy consumption of synthetic aperture radar, it is difficult to ensure continuous monitoring. At the same time, this method is mainly used in fishery monitoring and oil spill management. The scanning system was later developed into the visible infrared imaging radiation system VIIRS to collect DNB data, but this type of night ship detection method is also mainly aimed at fishing boat detection, and is rarely used in other scenarios
[0004] In view of the fact that there are few researches on the methods of detecting ships with ordinary cameras at night, how to collect the image features of sailing ships and realize ship detection and tracking is an urgent problem to be solved.

Abstract

The invention discloses a device for detecting and tracking ships at night, including a camera, an AIS berth, a communication server, a data center, and a monitoring terminal. The invention also discloses a method for detecting and tracking ships at night, based on the LOG operator Carry out light spot detection and Kalman filter multi-target tracking algorithm to realize ship tracking at night, and further integrate with AIS data to improve the accuracy of ship detection. The invention can be effectively applied to the detection and tracking of ships at night, and increases the detection methods of relevant departments on ships at night. In addition, the calculation by the computer using the method can realize real-time monitoring of the navigation situation of the waterway for decision-makers to understand and deal with in a timely manner, so as to achieve efficient and reasonable dispatch of ships.

Description

technical field [0001] The invention relates to the technical field of detection and tracking of ships sailing at night, and more specifically relates to a method for detecting and tracking ships at night based on video images, real-time AIS and communication equipment. Background technique [0002] Ship detection and tracking technology is of great significance to ensure the safe navigation of ships and reduce maritime accidents. There are various methods and equipment for ship detection and tracking, such as radar, AIS, and video. Under special circumstances, various types of monitoring effects are affected. For example, in the nighttime environment, visibility is low and vision is blurred. Although radar can aid navigation, the radar target is not intuitive enough to determine the type of target object. AIS signals are easily lost and are affected by shipboard equipment. Therefore, there are still deficiencies in the current application methods. Using video images and r...
