摘要
目前,我国的陆地地理信息数据比较丰富,但是水下的地形数据相对单一。在获取水下地形信息数据方面,无人测量船系统优势明显,已被持续应用到水下地形测量中,极大地提高了水下地形测量工作效率与质量。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。从结果来看,无人船在水下测量工作中,可以克服浅水区域和因危险无法进入测量的问题、有效地避免测量时的安全威胁,极大地提高了水下地形测量的效率和精度。
In the past,the underwater terrain survey was carried out by manual operation,and because of the complex terrain elements,there are often many difficulties in the measurement process. Because the data of underwater terrain information is far less abundant than that of land,unmanned survey ship system has more advantages and has been continuously applied to underwater terrain measurement,which has greatly improved the efficiency and quality of underwater terrain measurement. This paper first summarizes the current unmanned ship measurement system and introduces its working principle. The underwater measurements of unmanned ships were analyzed by means of experimental data. From the results,the use of unmanned ships in underwater measurement work has an excellent prospect. It can overcome the problems that can not be accessed in shallow water and effectively avoid safety threats during measurement,thus improving the efficiency and accuracy of measurement.
