Data cleansing of co-ordinate data

For reference

This is a data processor of cleaning and refining raw data to improve its quality and accuracy.

The raw data is a set of log text containing three dimensional coordinate points.

This contains the original log data that needs to be cleaned, and I hope that some of the processing methods of the algorithm can be shared with you.

result_2 图标

定位点跳变分散性在全局坐标系位置中的关系 结论:可以看到四个基站所围起来的全局坐标系下 靠近坐标系中心的位置,基准稳定度非常好,靠近坐标系边界时出现跳变误差,并且初步看来,这种误差存在一定的方向性: 1,误差可能是在边界上TAG与基站的极限拓扑构型(共线或共点导致) 2,误差在右上角边界的跳变更大,是否意味着现有天线波束指向性影响了计算距离,导致多径返回的距离参与到了计算中
