Abstract

The invention provides a shipborne water bank line overwater and underwater integrated measurement system integrated method; integration of hardware of a measurement system is realized through design of a multi-sensor lift platform of an integrated mapping device, and requirements of changing sensor upper and lower positions under different operating conditions of a measurement ship are met. The system designs a data acquisition display control software framework to realize multi-sensor collaborative data acquisition, point cloud real-time display and the like. Through point cloud data preprocessing, data interpolation, spatial registration and other steps, multi-source data are subjected to fusion and resolution, so as to obtain a point cloud product for solving problems of difficult-and-inappropriate-to-reach island topographic measurement and marine unit coastal zone and mud flat topographic survey. The method realizes water bank line overwater and underwater integrated measurement, overcomes limitation of a traditional measurement technology, greatly improves the efficiency of measurement, and provides a bran-new measuring technological means for high-precision three-dimensional measurement problems required by wisdom navigation channels, digital water conservancy, wharfs, bank lines, off-lying sea islands and various engineering construction.

Description

technical field [0001] The invention relates to the technical field of marine surveying and mapping, in particular to an integration method for a ship-borne water shoreline integrated above-water and underwater measurement system. Background technique [0002] Accurate seabed topography of islands (reefs) and continental shelves is an important basis for determining my country's territorial waters and exclusive economic zones. The survey of seabed topography and near-shore water topography in shallow water areas of remote islands and reefs has always been a difficult problem in the field of surveying and mapping at home and abroad. [0003] Traditional field surveying and mapping generally uses a ship-borne single-beam echo sounder for underwater shoal surveys, and technical means such as artificial beaches, aerial photography, and satellite remote sensing are used for water topographic surveys; the non-integrated surveying method not only makes the cost High, and it is diff...
