组合空间曲线任意点三维大地坐标的算法研究

由解析曲线任意组合形式成的空间复杂曲线上任意点的大地坐标对于各种工程特别是线形工程的设计和施工具有重要意义，随着全站型仪器的广泛使用和依据坐标管理的需求日益增加，这一问题变得更加突出。本文在总结复杂线形特性和设计方法的基础上提出一种适合于计算机实现的通用算法及其程序编制技术。

RESEARCHES ON 3 D COORDINATE ALGORITHMS FOR ARBITRARY POINT ON SEGMENTARY ANALYTIC SPACE CURVES

D Coordinates of arbitrary point on complex space curves which are composed of segmentaly analytic curves are important for designing and constructing of various engineering projects.Along with widely using electronical omnitheodolite as wess as increasing desires for working with coordinates,this problem becomes much more significant.On the basis of researches about properties and design methods of complex space curves,we submit a general algorithm and its program making methods of 3 D coordinate realtime calculating for arbitrary point on the curves.
