And the other is to get the data corrected using probe radius compensation, then to reconstruct.
另一种是利用测头半径补偿，将测得的数据修正后再进行反求。
The normal vector of each data point is calculated without reconstructing surface, and then realizing radius compensation with probe radius by going along normal vector.
在不需要重建曲面模型的情况下，找到每一个数据点的法矢，在该法矢方向上补偿一个球头半径实现了测头半径的三维补偿。
