摘要
水下地形测量因其局限性大、成本高、作业效率低,常规人工测量方法难以开展。随着测绘技术的发展,无人测绘船被投入水域测量工作。通过将GNSS RTK与声呐测深技术相结合,实现实时定位测量水底底面的高程,测量精度可达到厘米级,能够极大地提高作业效率,减少作业周期及成本。本文首先对无人测量船作业原理和流程进行了简单的介绍,结合应用实例,进一步论述了利用无人船测量水下地形的作业过程和方法。
Underwater topographic survey because of its limitations,high cost,low efficiency,conventional manual measurement method is difficult to carry out.With the development of surveying and mapping technology,unmanned surveying and mapping ship has been put into the water measurement work.Through the combination of GNSS RTK and sonar sounding technology,real-time positioning to measure the bottom of the bottom elevation,measuring accuracy of centimeter,can greatly improve the operating efficiency and reduce the operating cycle and cost.In this paper,the operating principle and process of unmanned survey vessel are briefly introduced.Combining with practical examples,the operation process and method of unmanned vessel to measure underwater topography are further discussed.
