摘要
分析了空间中两点距离在正交坐标系和球坐标系下的计算方法,推导出球坐标系下空间距离不确定度的公式,给出一种最小不确定度的特例,便于球坐标系使用者快速评价测量结果和优化测量布局。
The calculation methods of the spatial distance in the orthogonal coordinate system and the spherical coordinate system are analyzed, and the measurement uncertainty in the spherical coordinate system is derived, and an example of the minimum uncertainty is given. The spherical coordinate system user can quickly evaluates the results and optimizes the measurement layout.
