Embodiment Construction

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0056] An embodiment of the present invention provides a method for segmenting the trajectory of a sea target. The method divides the trajectory into sub-trajectories of a specified length in equal steps, and at the same time determines the trajectory type of the sub-trajectories, and performs operations such as merging, swallowing, and aggression ...

Abstract

The invention relates to the technical field of trajectory analysis, in particular to a marine target trajectory segmentation and description method, electronic equipment and a storage medium. The marine target trajectory segmentation and description method comprises the following steps: dividing a given trajectory into a plurality of sub-trajectories according to a trajectory segmentation rule; determining trajectory types of the sub-trajectories, and combining the sub-trajectories of the same type to optimize the trajectory to be composed of trajectory segments; phagocytosis is carried out on each track segment according to phagocytosis rules, so that the track is optimized to be composed of phagocytosis track segments; each phagocytic track section is infringed according to an infringedrule, so that the track is optimized to be composed of infringed track sections; and evolving each infringement track section according to an evolutionary rule to obtain a track composed of evolutionary track sections. According to the method, the track is segmented fully according to the shape characteristics of the track, so that the influence of environmental factors is eliminated; according to the method, seven behavior modes are adopted to segment and describe the track, and segmentation and description are accurate and reliable; in addition, the method is high in applicability.

Description

technical field [0001] The invention relates to the technical field of trajectory analysis, in particular to a method for segmenting and describing a trajectory of a sea target, electronic equipment and a storage medium. Background technique [0002] In the era of big data, the amount of data continues to increase, and mining meaningful information from massive data has become a hot topic today. People's daily travel will generate a large amount of trajectory information, and mining trajectory data can discover hot spots and people's behavior patterns. This technology is widely used in advertising placement, case analysis, and business decision-making, while maritime trajectory data mining is relatively less studied. For maritime targets, landmark references and road constraints are lacking. Sea targets move relatively freely, and there is no effective semantic reference for the segmentation and description of sea target trajectories. Therefore, it is of great significanc...
