需求
测绘时候经常用到rtk，可以测量一点的经纬度和高程，做控制点测量的时候，每个点需要测量多次，然后取平均值作为该点的最终值。
现在公司里有两套仪器，导出的格式略有不同，我们需要提取 点的编号、经度、纬度、高程 这4个数据，然后把同一个点的多次测量结果求平均值；另外需要GUI界面，降低操作难度；其次，有时候需要同时使用多台仪器测量，所以要能一次输入导出的多个文件，输出一个最终处理结果；最后，处理结果要求可以选择csv、xlsx、dat三种格式，有时候要xlsx格式上报，有时候需要dat格式导入cass，有时候需要csv格式便于查看。
思路
- 判断输入的数据是哪套仪器导出的
- 提取 点编号、经度、纬度、高程
- 间距小于0.1的点视为同一位置的多次测量结果，要对这些点求均值，测量的次数不固定，可能有任意多个
- 输出结果到一个文件
- 写个界面包装下

运行
只要将仪器导出的文件拖入或者点击右侧按钮打开文件，就可以开始处理任意数量的文件，右侧还可以选择处理结果的格式，默认为csv和dat格式，点击开始处理，处理完毕后会自动打开文件便于查看。一般按下开始处理按钮，数据就处理完了，比以往要快很多。
