The coastal engineering of the port area is special and complex due to the terrain of the water and land. The manned measurement ship was unable to enter the test area and some areas limit the UAV. This paper presents an integrated measurement method that combines unmanned ship sounding with 3D laser scanning. Its practical application in Guangxi Port Area coastal engineering shows that measurement data fusion control and point cloud integration technology can safely and efficiently obtain high-density point cloud data across the entire survey area. The accuracy of the results meets the operational specifications' requirements and can serve as a reference for comprehensive survey technology applications in coastal engineering.
