Abstract

The invention discloses a sea chart selection method and device based on a planned route. The method comprises the following steps of determining a escorting region corresponding to the planned route based on the obtained planned route and a preset yaw distance, and the escorting region comprising the planned route; obtaining a sea chart icon which has an intersection with the escorting region; and determining the sea chart corresponding to the sea chart icon as the sea chart corresponding to the planned route. The method can determine the escorting region including the planned route based on the obtained planned route and the preset yaw distance, obtains each sea chart icon having intersection with the escorting region, and finally determines the sea chart corresponding to each obtained sea chart icon as the chart corresponding to the planned route. a ship can obtain the accurate sea chart in the sailing process, and sailing safety of the ship is improved.

Description

technical field [0001] The invention belongs to the technical field of navigation and navigation, and in particular relates to a method and device for selecting a sea chart based on a planned route. Background technique [0002] At present, ships generally need to select required charts for navigation according to pre-planned routes during navigation. However, due to the effects of waves and currents during the ship's navigation, the ship usually does not sail according to the planned straight line, and generally has a certain yaw. When the ship yaws, based on the pre-planned straight line The chart selected for the route may not match the sea area where the ship is currently located, resulting in the inability of the ship to obtain accurate charts during the voyage, which reduces the safety of the ship's navigation. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a sea chart selection method and device b...
