摘要
GPS高程转换的方法有很多,BP神经网络法是近几年兴起的一种新的方法。在采用BP神经网络法进行GPS高程转换的过程中,一般来说需要编写专门的应用程序来完成相应的计算,这对无编程经验的工程技术人员来说存在着一定的困难。而利用Matlab提供的网络工具箱不用编程即可计算出高程异常,极大地方便了广大工程技术人员。论文介绍了基于Matlab的BP神经网络法GPS高程转换的计算步骤,结合一工程实例讨论了不同网络参数的设置对转换结果的影响。
BP neural network method is one of new methods for GPS height transformation. During using BP neural network method for GPS height transformation, the engineers and technicians must write an application program to calculate the height anomaly which is. difficult to them. But the application of Matlab network toolbox can calculate the height anomaly quickly without writing program, which is convenient to the engineers and technicians. This paper introduced the calculation steps of GPS height transformation with neural network method based on Matlab, discussed the network parameters of different settings on the impact of the conversion results.
