精密测距在奥运场馆建设中的应用

Application of Precision Ranging to the Construction of Olympic Venues

介绍了一种使用全站仪同向观测、利用差值计算,配合垂直方向全站仪定位,精确测定泳池长度的方法,克服了现场无法架设仪器和目标棱镜的困难,减少了投点误差、仪器常数误差的影响,该方法还可以用于检验标准长度和仪器加常数。

This article introduced a method used to measure the swimming pool＇s length accurately by observing it in the same direction using total station,calculating difference in value and positioning the total station in the vertical direction.The method helped to solve the problems that we meet when we cannot set the equipments and target prism.Meanwhile,the effect of throwing-dot error and equipment constant error was reduced.It also helped to inspect the standard length and equipment addition.
