摘要
随着空间定位技术的普及,不同空间直角坐标系间的转换过程中经常遇到问题不易被解决。本文首先介绍了不同空间直角坐标系间转换时广泛使用的布尔沙转换模型并阐述了七参数求解的过程,然后结合ACCESS中的表、窗体和宏,利用VBA实现了基于布尔沙转换模型的七参数计算程序,并结合实例对所编写的程序加以验证,保证其结果的可靠性。
With the popularity of the spatial positioning technology, the conversion between different spatial rectangular coordinate systems is often encountered and problems are difficult to be solved. This paper firstly introduces Bursa seven - parameter conversion model which is widely used in the conversion between the different spatial rectangular coordinate system and describes the seven - parameter for solving process, and then combine the tables, forms, and macros in the Access, Meanwhile, achieve the seven - parameter calculation program based on Bursa conversion model through VBA and associate some illustrations to verify written procedures in order to ensure the reliability of the results finally.
