Abstract

The embodiment of the invention provides an unmanned ship path optimization method and system based on multi-objective optimization, and the method comprises the steps: taking each path point in a current planning path of an unmanned ship as a basis, considering the multi-point constraint, obstacle avoidance and other natural condition constraints, carrying out the path point division again, comprehensively considering the path length, path smoothness and path safety, and improving the path optimization efficiency. And multi-objective optimization of path length, path smoothness and path safety is realized, so that a global path conforming to the actual navigation of the unmanned ship is planned.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of unmanned ships, in particular to a method and system for unmanned ship path optimization based on multi-objective optimization. Background technique [0002] As an important measure of the national economic strategy, the research and application of unmanned ships has promoted the development of marine economy, which is conducive to reducing the cost of marine transportation and labor costs. It can be applied to various engineering minerals, fishery transportation, ship and island resource supply, and marine Surveying and hydrological monitoring. 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 ...
