球形金属罐全站仪测量方法探讨

Discussion on Measurement Method of Spherical Metal Tank Total Station

本文讨论以下三个问题:一是提出计算球心方向和切点方向立体夹角θ的方法;二是通过切点的水平角和天顶距拟合球心的方法计算球体半径;三是解决规程中测量方法测点数量少代表性不够的问题。

The paper discusses the following three problems： one is the center point method is put forward to calculate the direction and direction of solid angle; two is to calculate the radius of the sphere method by point horizontal angle and zenith distance fitting sphere heart; the three is to solve the measuring point number represented measurement methods for.
