在高速铁路精密工程测量工作中，经常会涉及到CPIII控制测量的工作以及内业CPIII观测数据的处理，CPIII外业测量采用智能型全站仪进行测量，智能型全站仪可以自动照准目标，自动测量，自动保存观测数据。但内业工作中仍然要对外业得到的角度和距离的观测数据进行平差处理，由于CPIII观测数据的量往往非常大，所以开发出一个能够对CPIII外业观测数据进行批量处理的小工具就很有必要了。下面对该小工具进行介绍并附上核心代码，希望大家多多支持。
CPIII观测数据平差处理工具的界面如图所示
CPIII一个测站的观测数据文件格式如图所示，有几个测站就有多少个观测文件，该程序可以一次打开多个观测数据文件
CPIII观测数据处理软件平差得到的结果如图所示
最后附上程序的核心代码
