基于IDL编程语言实现大地坐标转换

Coordinate transformation based on IDL programming language

由于实际测量时,所使用的仪器不具备自动统一在大地绝对坐标系的功能,采集的数据点是以测量点为中心的相对坐标,给研究带来了不小的麻烦.为了解决这一问题,借用某矿山的三维激光扫描数据,利用IDL编程语言实现相对坐标与大地绝对坐标的自动转换,自动转换程序大大节省了建模时间,并满足实际研究需要,以供后续研究人员参考.

As a result of the actual measurement,the instruments used not to have the function of automatically unifying the absolute coordinate system,and the collected data are relative coordinates centered on the measurement point,which has brought trouble to the research.In order to solve this problem,we use the IDL programming language to realize the automatic conversion of relative coordinates and absolute coordinates of the earth,which greatly saves the modeling time and satisfies the actual research needs for the reference of the researchers.
