| 摘 要： | 随着社会经济的迅速发展,高耸建(构)筑物越来越多,为了精确测量这些建(构)筑物的高度,为工程施工建设和安全提供可靠依据,很多测量工作者采用了全站仪悬高测量的方法并对其进行了一些改进。文章在介绍传统悬高测量方法的基础上,提出一种无需量取仪器高,避免寻找待测目标的垂直投影点且适合多数特殊情况下高度测量的新方法,并对其计算公式进行了推导和误差分析。通过实例验证了该方法的可行性,一般情况下测量精度能达到毫米级,满足大多数高度测量的精度要求。

Rediscussion on the method of REM |

| Abstract: | With the rapid development of the social economy,towering buildings are more and more.In order to accurately measure the height of buildings to provide the reliable basis for the construction and security of project,many surveyors are applying the improved method of total station REM.On the basis of introducing conventional method of REM,this paper puts forward a new method which don't need to measure the height of the instrument,and avoid looking for the vertical projection of targets.The method can fit the measure of the height in the majority of special circumstances.On the other hand,the calculation formulas for the method are derivated and relevant error analysis is discussed.Through the example,the feasibility of the method has been confirmed.The measuring accuracy can achieve mm level under ordinary circumstances and meet the majority of precision measurement requirements. |
