Embodiment 1

[0045] Such as figure 1 As shown, Embodiment 1 of the present invention provides a method for generating a sea route network, comprising the following steps:

[0046] S1. Obtain the ship trajectory of each ship within a certain period of time in the observed water area;

[0047] S2. Extracting feature points in the ship trajectory to generate a feature trajectory;

[0048] S3. Perform density clustering on each of the feature points to obtain multiple clusters and corresponding cluster center points;

[0049] S4. Using the cluster center point as a waypoint, replace each feature point in the feature trajectory with a waypoint of a corresponding cluster cluster to generate a route trajectory;

[0050] S5. Connect each waypoint in the route track in sequence to generate a route network.

[0051] The sea route generation method provided in this embodiment is different from the method of road traffic and air traffic that constructs a road network based on traffic facilities and...

Embodiment 2

[0107] Embodiment 2 of the present invention provides a device for generating a sea route network, including a processor and a memory, where a computer program is stored on the memory, and when the computer program is executed by the processor, the sea route network provided in Embodiment 1 is realized. generate method.

[0108] The sea route network generation device provided by the embodiment of the present invention is used to implement the sea route network generation method. Therefore, the sea route network generation device also possesses the technical effects of the sea route network generation method, and will not be repeated here.

Embodiment 3

[0110] Embodiment 3 of the present invention provides a computer storage medium on which a computer program is stored, and when the computer program is executed by a processor, the method for generating a sea route network provided in Embodiment 1 is realized.

[0111] The computer storage medium provided by the embodiment of the present invention is used to implement the method for generating the sea route network. Therefore, the technical effects of the method for generating the sea route network are also provided by the computer storage medium, and will not be repeated here.

[0112] The ship trajectory analysis method, device and computer storage medium provided by the present invention do not need to rely on infrastructure or special road sections in the route network when establishing a route network, and only need to obtain the ship trajectory within a certain period of time, and analyze and mine the ship trajectory based on the ship trajectory. waypoints in the route ne...

Abstract

The invention relates to a marine route network generation method and device and a computer storage medium, and the method comprises the following steps: obtaining the ship trajectory of each ship in an observation water area in a certain period of time; extracting feature points in the ship trajectory to generate a feature trajectory; performing density clustering on each feature point to obtain a plurality of clustering clusters and corresponding clustering center points; taking the clustering center point as a marine route point, replacing each feature point in the feature track with the marine route point of the corresponding clustering cluster, and generating a marine route track; and sequentially connecting the marine route points in the marine route track to generate themarine route network. The marine route network is constructed based on the ship trajectory, and the construction precision is high.

Description

technical field [0001] The present invention relates to the technical field of route networks, in particular to a method, device and computer storage medium for generating a sea route network. Background technique [0002] The shipping route is the main route of the ship's navigation. Usually, the trajectories of the ship's navigation are gathered near the shipping route. The airway network is a topological structure composed of each waypoint and airway, and the structural characteristics of the airway network are of great concern to practitioners. [0003] Road network research first started in the field of road traffic, and later expanded to the field of air traffic and water traffic. The basic logic is to use traffic infrastructure such as stations, intersections, airports, ports, or special road sections as network nodes to construct traffic networks. There is a big difference between water traffic, road traffic, and air traffic. In water traffic, there is no boundary c...
