一种水下点位三维坐标精准测量的方法

A method for accurate measurement of three-dimensional coordinates of underwater point position

海洋测量、水下地形测量、水务监管中的河道测量已经越来越多,但精度较差,在涉及需要精密定位的水下建(构)筑物时,应用方法有限,基本还是需要全站仪、水下近景摄影测量等方法。结合某个水下三维坐标精确测量的经验,用全站仪方法,从方法创新、测绘组织、数据处理等方面介绍一种基于利用几何关系计算来进行水下点位三维坐标测量的方法。

The ocean surveying in marine survey,underwater topographic survey,water supervision had become more and more numerous,but the accuracy was poor,when it came to underwater construction structures that required precise positioning,the application methods were limited,basically needed the whole station instrument,underwater near-view measurement and other methods. Combining with the experience of accurate measurement of an underwater three-dimensional coordinates,introduced a method of three-dimensional coordinate measurement of underwater point position based on geometric relation calculation from the method innovation,mapping organization,data processing and other aspects.
