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:
Point cloud with normals.
Parameters for setting the region of interest.
Output:
Mask for regions with standard deviations of normals greater than the threshold.
