An inland river complex water area underwater topography measurement system comprises an unmanned aerial vehicle system, a small depth finder and a ground station system, the small depth finder is connected with the lower portion of the unmanned aerial vehicle system, and the ground station system is connected with the unmanned aerial vehicle system. The unmanned aerial vehicle system comprises anunmanned aerial vehicle, a high-voltage battery module, a GNSS module, a self-stabilization holder, a flight control module and a data transmission module. The unmanned aerial vehicle system is additionally arranged, the unmanned aerial vehicle is adopted as a carrier, the unmanned aerial vehicle is automatically remotely controlled to fly to a measuring point, and automatically descends until adepth finder transducer is immersed in a position 10-20 cm below the water level, and the unmanned aerial vehicle position and depth measurement information are returned to the ground station system through the unmanned aerial vehicle data transmission module, so underwater topographic measurement is automatically implemented in the whole process, measurement data can be transmitted back to the ground station in real time in a wireless mode, manual wading measurement is not needed, the safety risk is low, and the operation efficiency is high.

    一种内河复杂水域水下地形测量系统,包括:无人机系统、小型测深仪和地面站系统,小型测深仪与无人机系统下部连接,地面站系统与无人机系统连接。其中,无人机系统包括:无人机、高压电池模块、GNSS模块、自稳云台、飞控模块和数据传输模块。本发明与传统技术相比,通过增设无人机系统,以无人机作为载体,自动化遥控无人机飞抵测点,自动降高至测深仪换能器没入水中10~20cm,通过无人机数据传输模块,将无人机位置及测深信息返回至地面站系统,全程自动化实施水下地形测量,且测量数据可无线实时回传至地面站,无需人工涉水测量,安全风险低,作业效率高。
