Extract Regions of Large Normal Deviations

Function

This Step extracts regions where the normals have large standard deviations. It maps the normals onto a 2D image first, and then uses a 2D filter to calculate the local standard deviations and generate a mask of regions with standard deviations larger than the set threshold.

Usage Scenario

This Step is a custom Step for special scenarios.

Input and Output

  • Input:

  1. Point cloud with normals.

  2. Parameters for setting the region of interest.

  • Output:

  1. Mask for regions with standard deviations of normals greater than the threshold.
