摘要
各种工程对测量的精度要求越来越高,仪器高的量取是测绘中的首要程序,仪器高的精度决定了测量外业的整体精度。本文介绍了量取仪器高的一般方法,并在对现有三脚架作出局部改动的基础上,配对一种新设计的尺子,提出了一种新的仪器高量取方法。该方法操作简便,可行性强,可提高仪器高的测量精度,具有很强的普及性。本文的设想为测量工作中仪器高的量取提供了新的参考,也为仪器改良提供了新的思路。
Demands of various engineering on measuring accuracy are higher and higher,The first program in surveying and mapping is measuring instrumental height,the precision of measuring instrumental height will determine the overall precision of the measurement field. This paper introduces the common methods of measuring instrumental height,and makes local changes to tripod and matches a new design of a ruler. In the end,it puts forward a new method of measuring instrumental height,which is simple in operation and have good feasibility. In addition,it can improve the accuracy of measuring instrumental height and gain high popularity. In this paper,the idea provides a new reference for measuring instrumental height in measurement field and provides a new idea for improve instrument.
