摘要
常规的水下地形测量需要分别测定测点的平面坐标、水深以及水位高程获得水下地形的绝对高程,过程较为繁琐.为及时高效地获取水下地形的三维坐标成果,本文依托方正县双凤水库项目数据提出基于HLJCORS系统的单波束测深系统在水下地形测量工序.该工序是通过在数据采集软件端将GNSS设备采集到的三维坐标和测深仪测得的深度进行叠加,获得瞬时水下地形点的三维坐标,减少了潮汐观测程序.该方法的提出有助于CORS系统在水上项目的应用推广,同时为类似水下地形测量项目提供了参考.
Abstract
Conventional underwater topographic survey needs to measure the planimetric coordinates,water depth and water level ele-vation of the measuring points to obtain the absolute elevation of underwater topography,which is complicated. In order to obtain the 3D coordinate results of underwater topography in a timely and efficient manner,this paper proposes a single beam sounding system based on HLJCORS for underwater topography survey of Shuangfeng Reservoir in Fangzheng county. This procedure is to obtain the three-dimensional coordinates of instantaneous underwater topographic points by superimposing the three-dimensional coordinates col-lected by GNSS equipment and the depth measured by the sounding system in the data acquisition software,which reduces the tide ob-servation program. The proposed method is helpful to the application and promotion of CORS system in water projects,and also pro-vides reference for similar underwater topographic survey projects.
