The invention discloses an underwater traverse measurement method and device for acquiring submarine control point data, and the method comprises the following steps: designing an underwater traverse measurement mode, and taking an integrated measurement ship carrying GNSS, inertial navigation and underwater sound ranging equipment as a core observation instrument; a GNSS benchmark of a land datum point is used as a reference, a tide gauge or a water level gauge is used as an auxiliary, and three types of data of geodetic height, normal height and water depth of a seabed control point are respectively obtained through an inverted long baseline positioning principle, a transmission datum value and an average water level gauge. The device comprises a processor and a memory.
本发明公开了一种获取海底控制点数据的水下导线测量方法及装置,所述方法包括以下步骤:设计水下导线测量模式,将搭载GNSS、惯导和水声测距设备的一体化测船作为核心观测仪器;以陆地基准点的GNSS水准点为参考,辅以验潮仪或水位计,通过倒长基线定位原理、传递基准值和平均水位计,分别获得海底控制点的大地高、正常高和水深三类数据。装置包括:处理器和存储器。
