摘要：

提出了基于公共光学基准的大尺寸空间的角度测量方法。通过在数米至十几米的大尺寸空间内建立公共光学基准,结合视觉测量和计算机图像处理技术,借助测量公共方向基准与各个几何元素之间的夹角,可简便地实现对大尺寸空间的异面几何元素之间夹角的测量。分析了建立公共光学基准的方法。按照所提出的测量方法,对相距7m的两条异面直线的空间夹角成功地进行了现场测量。

Abstract:

A method for measuring the angles in large-scale space based on a common optical reference was proposed. By setting up the common optical reference in large-scale space within several to tens of meters, by combining vision inspection technique and image processing technique, the angle among the elements separated at a large distance was determined in a relatively simple way by measuring the angle among reference and each element. In addition, the ways of forming a common optical reference were analyzed. Based on the proposed principle, a practical example of angle measurement formed by two axes separated at a distance of 7m was shown. 

Key words: large-scale space, angle measurement, common reference, optical reference
