SOR filter

Menu

This tool is accessible via the the icon in the upper main toolbar or the Tools > Clean > SOR filter menu.

Description

The 'SOR filter' tool resembles a lot the S.O.R. (Statistical Outlier Removal) of the PCL library. It computes first the average distance of each point to its neighbors (considering k nearest neighbors for each - k is the first parameter). Then it rejects the points that are farther than the average distance plus a number of times the standard deviation (second parameter).

Input

One or several clouds (selected in the DB tree).

Parameters

The user has to:

• choose the number of neighbors that will be used to compute the 'distance to neighbors' for each point
• and set the number standard deviation multiplier (the max distance will be: average distance + n * standard deviation)

SOR filter parameters

Output

A new cloud, hopefully cleaner ;)

Note

This tool replaces the S.O.R. method of the qPCL plugin (this is why it has the same icon).
