The invention relates to the technical field of underwater topographic survey, and discloses an underwater topographic survey system and an antenna relative position relation obtaining method, the system comprises a transducer assembly, an orientation module, a positioning module, a sighting assembly and an acquisition assembly, the transducer assembly is suitable for being arranged on a ship board, the orientation module is suitable for being arranged at the top of a ship cockpit, and the positioning module is suitable for being arranged at the bottom of the ship cockpit. The positioning module is suitable for being arranged at the top of a ship cockpit, the transducer assembly, the orientation module and the positioning module are in signal connection, the sighting assembly is suitable for being arranged at the top of the transducer assembly, and the collecting assembly is suitable for being arranged at the top of the ship cockpit and located above the positioning module or the orientation module and obtaining position information of the sighting assembly. According to the invention, the orientation module and the positioning module are arranged at the top of the ship cockpit, so that the stability and accuracy of the received signal can be ensured due to no shielding around the orientation module and the positioning module when the GNSS signal is received, thereby ensuring the accuracy of the underwater terrain detection data.

    本发明涉及水下地形测量技术领域,公开了水下地形测量系统及天线相对位置关系获取方法,系统包括换能器组件、定向模块、定位模块、照准组件以及采集组件,换能器组件适于设置在船舶船舷上,定向模块适于设置在船舶驾驶舱顶部,定位模块适于设置在船舶驾驶舱顶部,换能器组件、定向模块和定位模块信号连接,照准组件适于设置在换能器组件顶部,采集组件适于设置在船舶驾驶舱顶部,位于定位模块或定向模块上方,采集组件适于获取照准组件位置信息,本发明通过将定向模块与定位模块设置在船舶驾驶舱顶部,在接收GNSS信号时由于定向模块与定位模块周围无遮挡,可保证接收信号的稳定与准确性,从而保证了对水下地形检测数据的准确性。
