Automatic Behavior division method and system based on ship trajectory, and electronic equipment

Abstract

The invention discloses an automatic behavior division method and system based on ship trajectories and electronic equipment, and the method comprises the steps of carrying out the preprocessing of multi-ship trajectory data, designing a division cost function, carrying out the common behavior pattern discovery of multiple ships in the same channel at a time level and an individual level, further carrying out the division of the trajectories, meanwhile, dynamically determining an optimal behavior pattern number and a division scheme, and generating a division result. According to the ship automatic behavior division method based on the multi-ship trajectory, complete motion information (including longitude and latitude, speed to the ground, course to the ground and the like) of the ship can be reserved, expansion can be achieved along with increase of the number of the ships and time-space characteristics, meanwhile, manual parameter setting and adjustment are avoided, and the automatic behavior pattern recognition and division of the ship trajectory are realized.

Description

technical field [0001] The invention belongs to the field of computer big data processing, and relates to a ship behavior automatic division method, system and electronic equipment, in particular to a ship track-based automatic behavior division method, system and electronic equipment. Background technique [0002] During the voyage of the ship, the sensors carried on the ship will record the ship's trajectory data, and a lot of valuable information can be mined from these data, which can be applied to shipping management, ship collision avoidance and other fields. However, due to factors such as complex and changeable navigation environment and equipment failure, ship trajectories often have problems such as low sampling rate, many noise points, uneven particle size, and irregular changes, which bring difficulties to the processing and analysis of navigation trajectories. Therefore, it is necessary to identify the different behavior patterns existing in the ship's trajector...

Problems solved by technology

However, these methods often only focus on one of the ship's motion parameters and trajectory space structure, and cannot retain the complete information of the ship's motion process, and need to manually adjust the model parameters

In addition, the traditional method focuses on the behavior division of a single ship trajectory, and cannot distinguish the common behavior patterns of multiple ships on the same customary route and the unique personalized behavior of some ships, and cannot adapt to the needs of complex and changeable navigation scenarios.
