基于无人船测量系统的水下地形测量研究与应用

随着测深技术、GNSS技术、高精密传感器集成化的发展，无人船测量系统为水下地形测量提供了新的思路。结合山东省高密市王吴水库，探讨了无人船水下地形测量的作业流程，通过对比分析，选择最优测线间距获取数据，通过差值分析进行精度评价，数据处理后对成果进行展示。研究区结果表明，无人船测量系统基于单波束测深在中型水库中的应用是十分理想的，测深数据质量较好，能够很好地反映库区的水下地形情况，无人船测量系统在水下地形测量中起着重要作用。

Study and Application of Underwater Topographic Survey Based on Unmanned Ship Survey System

Accompanying with the development of sounding technology, GNSS technology and high precision sensor integration, unmanned ship survey system provides new ideas for underwater topographic survey. Combining with Wangwu reservoir in Gaomi city in Shandong province, unmanned ship underwater topographic survey process has been studied. Through comparison and analysis, selecting the optimal survey line spacing to obtain data, evaluate the accuracy through difference analysis, and display the results after data processing. It is showed that the application of the unmanned vessel survey system based on single beam bathymetry in mediumsized reservoirs is very ideal, the quality of bathymetric data is good. It can well reflect the underwater topography of the reservoir area. The unmanned vessel survey system plays an important role in underwater topographic survey.
