摘要
探讨我国常用坐标系与CGCS2000坐标系的转换方法。以平面四参数、三维七参数数学模型为基础,分析其不同转换模型的内涵和适用性,并以MATLAB为平台实现常用坐标系到CGCS2000国家大地坐标系的转换,转换结果达到厘米级,满足实际工作的精度要求。
It discusses the method of coordinate transformation between local coordinate and CGCS2000,based on the transformation models of two-dimensional four parameters and three-dimensional seven parameters,aiming to achieve the conversion from local coordinate to CGCS2000 with MATLAB for platform.At the same time it analyzes the applicability and the principle of both conversion models.The conversion precise reaches to the centimetre that accords with actual project.
