Abstract: As a new technique, the integrated measurement in the water and above has been used in ship-borne integrated measurement system in recent years. The integrated measurement above and below water can be realized by the combination of multi-beam echo sounder(MBES), laser scanner and position and orientation systems for marine vessels etc. For the actual island (reef) mapping, the difficulty of landing on the island, the poor working conditions on the island, the heavy mapping tasks, and the difficulty coefficient, this paper introduces a shipborne multi-sensor integrated measurement technology. Through ship-borne integrated measurement system in water and above implements the offshore integration measurement cases of island reefs, water structures, port areas, etc. We clarify the advantages and disadvantages of the system in the application, and develop ideas for the further application of ship-borne integrated measurement system in water and above.
