Abstract

The invention discloses a water area shoreline construction method and system based on an unmanned ship. The method comprises: acquiring the position of an unmanned ship; downloading a satellite map of an area where the position is located according to the position; extracting a water area boundary of the satellite map to obtain an initial boundary; controlling the unmanned ship to sail along theinitial boundary, and acquiring laser point cloud data scanned by a three-dimensional laser scanner in navigation and pictures collected by a camera; extracting a water area boundary according to thelaser point cloud data to obtain a first water area shoreline; extracting a water area boundary according to the picture to obtain a second water area shoreline; and coupling the first water area shoreline and the second water area shoreline to obtain a constructed water area shoreline. According to the unmanned ship-based water area shoreline construction method and system, the accuracy of waterarea shoreline construction can be improved.

Description

technical field [0001] The invention relates to the field of shorelines in water areas, in particular to a method and system for constructing shorelines in water areas based on unmanned ships. Background technique [0002] In the application of unmanned ships, the topography and shoreline of the water area are important basic data. Only by knowing the accurate shoreline data, the operator can design a reasonable planned route according to the actual situation. Shoreline data is also necessary data when using the collected data to accomplish industry achievements. In addition, measuring the shoreline of water areas is also an important geographic information data, and it is one of the important daily tasks of hydrology, water affairs, and land surveying and mapping departments. [0003] At present, there are two methods of constructing water coastlines: [0004] 1) Use existing data or satellite maps to outline the shoreline of the water area. However, compared with land ...
