关于尼日利亚现代化铁路坐标转换的探索

摘要

The basic task of measurement is to determine the position,attitude and trajectory of objects in space,while the description of these features is built on a particular space frame.The so-called space frame refers to the coordinate system as is known.a variety of methods are used to describe spatial locations,thus different coordinate systems came into practice. This paper introduces the method of converting different coordinate systems.%测量的基本任务就是确定物体在空间中的位置、姿态及其运动轨迹,而对这些特征的描述都是建立在某一个特定的空间框架之上的。所谓空间框架就是常说的坐标系统。为了描述空间位置,采用了多种方法,从而也产生了不同的坐标系。主要介绍了不同坐标系之间相互转换的方法。
