Title:
DYNAMIC PATH PLANNING METHOD AND DEVICE FOR COVERAGE FEEDING OF UNMANNED SHIP
Document Type and Number:
WIPO Patent Application WO/2021/232583
Kind Code:
A1
Abstract:
Disclosed are a dynamic path planning method and device for coverage feeding of an unmanned ship. The method comprises: acquiring first vertex group positioning information of a water region, the feeder range distance, and unmanned ship positioning information; establishing a region model according to the first vertex group positioning information, and obtaining path planning points according to the region model and the feeder range distance; obtaining path target points according to the first vertex group positioning information and the path planning points; according to the unmanned ship positioning information and the path target points, dividing the path target points into unreached target points and reached target points; and obtaining a cruising path according to the unmanned ship positioning information and the unreached target points. In the present invention, a cruising path is dynamically generated by means of determining the unreached target points, which may ensure that once the unmanned ship deviates from a predetermined cruise path due to various factors, the unmanned ship travels according to the current optimal cruise path and performs full coverage feeding, thereby improving output value and efficiency.
