About Reducing Noise
Due to the limitations of scanning devices, the points in the scanned data may deviate from their original location. This deviation is the noise in the point set.
The Reduce Noise command uses statistical methods to determine the correct location for the points and moves the points to that location. Based on the level of noise or deviation of points in the point set, you can choose the level of noise reduction.
