摘要
本文绘出一种根据三斜距解算点的三维坐标的直接方法,无需初值、迭代及多值判断,非常适合计算机编程;给出的实用精度估算式能方便地实现根据三斜里估算待定点三维点位精度之目的;对其应用条件的讨论,提出了应用中的具体倾角限值,对指导实际工作具有重要意义。
In this paper,a direct soltion method to determine the 3-D coordinates of the unknown point by three observed distances is presented,which doesn't require initial values,iteration and multi-values judgment,and is suitable for computer programming.A practical formula of accuracy estimate is also introduced,which can be easily used to calculate the 3-D position precition by three observed distances.Through discussion of the application condition of this network,some suggestions about inclined angles limits are proposed,which possess important signification for practical jobs.
