Abstract

The invention discloses a submarine topography drawing method and a device. The method comprises the following steps of: obtaining the water depth of each reference position of the unmanned ship in the designated area and the water flow speed of each reference position; and calculating a water flow speed difference value between two adjacent reference positions, judging whether the water flow speed difference value between the two reference positions is greater than a preset value, and if the water flow speed difference value between the two adjacent reference positions is greater than the preset value, performing interpolation processing on the water depth between the two adjacent reference positions to obtain a submarine topography drawing result. The submarine topography drawing methodprovided by the embodiment of the invention greatly improves the submarine topography accurate measurement and efficiency.

Description

technical field [0001] The invention relates to the field of unmanned ships, in particular to a method and device for mapping seabed topography. Background technique [0002] Unmanned ship is a new product that utilizes modern unmanned technology and multi-field technology fusion, and has obvious advantages over traditional ships. It can navigate on the water surface according to preset tasks without remote control, with the help of precise satellite positioning and its own sensing, and is widely used in surveying and mapping, hydrology and water quality monitoring. [0003] The seabed terrain mapping scheme in the existing technical schemes has low measurement efficiency and measurement accuracy. Therefore, a scheme for sea (lake or river) bottom topography measurement is urgently needed at present. Contents of the invention [0004] In view of the above problems, embodiments of the present invention are proposed in order to provide a seabed terrain mapping method and de...
