%X 为解决水下地形测量中全站仪测量精度不足、工作效率低、定位精度低等问题，基于GNSS-RTK和声纳技术，本文设计了一种便携式水下河床地形测量装置。本文介绍了该装置的组成部分，并结合试验分析了该装置在中小河床地形测量中的测量误差，研究了该装置在水下地形测量中的应用可行性。研究表明，该装置在河床断面测量中测量精度可达12 mm，便携式水下地形测量装置的工作效率较全站仪提高了94.42%，该设备自动收集的数据可以通过5G技术传输到计算机，并绘制成河床的横断面视图。<br />
In order to solve the problems of low measuring accuracy, low working efficiency and low positioning accuracy of total station in underwater topographic survey, a portable underwater riverbed topographic survey device was designed based on GNSS-RTK and sonar technology. This article introduces the components of the device, analyzes the measurement error of the device in small and medium-sized riverbed terrain measurement through experiments, and the feasibility of the application of the device in underwater topographic survey is studied. The results show that the measuring accuracy of the device can reach 12 mm in the riverbed section measurement. The working efficiency of the portable underwater topographic survey device is 94.42% higher than that of the total station. Data automatically collected by the device can be transmitted to a computer via 5G technology and plotted into a cross-sectional view of the riverbed.
