无人船测量——一种新型水下地形测量方法

Unmanned Ship Surveying: A New Type of Underwater Topographic Surveying Method

随着我国基础设施建设的加快,传统水下地形测绘技术与方法中人员的安全问题与测量结果精度偏差等问题也开始显现,而无人测量船以GNSS与测深仪相结合的模式,在给外业测量人员安全保障的同时,将测量所得结果的精度大大提高,解决了传统水下地形测量作业中遇到的问题。本文介绍了无人测量船的组成与工作原理,并根据在广东省管网项目中无人船作业的实际案例,分析了无人船技术在水下地形测量中的优点与缺点,为水下地形测量提供一种新的方法与思路。

With the acceleration of China′s infrastructure construction, problems such as personnel safety and measurement accuracy deviations in traditional underwater topographic surveying and mapping technologies and methods have also begun to appear. While guaranteeing the safety of surveyors in the field, the accuracy of the measurement results is greatly improved, which solves the problems encountered in traditional underwater topographic surveying operations. This article introduces the composition and working principle of the unmanned survey ship and analyzes the advantages and disadvantages of the unmanned ship technology in the underwater topographic survey based on the actual case of the unmanned ship operation in the pipeline network project of Guangdong Province. It provides a new method and idea.
