Abstract

The invention discloses an unmanned ship sailing state control method based on sensing data. The method comprises the following steps: acquiring sensing data of an unmanned ship in a sailing process, and calculating unmanned ship state data at the current moment according to the sensing data; generating a local chart according to the unmanned ship state data; extracting environment target features to be matched with known environment target features, and updating the generated local chart by utilizing the matched optimal environment target features; and controlling the sailing state of the unmanned ship by using the updated local chart. According to the invention, the sensing data of the multi-sensor information is fused, and the sensing data is utilized to generate and update the local chart so that the sailing state of the unmanned ship is controlled, and the real-time performance and accuracy of the autonomous sailing of the unmanned ship are improved; and the autonomous navigation performance of the unmanned ship is evaluated by adopting the course keeping performance and the track tracking performance so that the autonomous sailing and accuracy of the unmanned ship are further improved.

Description

technical field [0001] The invention relates to the technical field of autonomous navigation of unmanned ships, in particular to a method for controlling the navigation state of unmanned ships based on sensing data. Background technique [0002] As marine resources are more and more valued by the state, offshore exploration and transportation activities continue to be frequent, and technology continues to develop and progress, intelligent, systematic and unmanned ship systems have become a new development direction. In recent years, through the combination of ships and advanced control technology, a new type of research topic-surface unmanned ship has been developed. Unmanned surface platform.
