POINTS FILTERING

JRC 3D Reconstructor Points filtering

In this tutorial you will learn how to

Simplify the structured or unstructured Point Cloud data created

Delete the Pre-processing filters already applied*

Merge together a group of scans

Extract edges: depth and discontinuities edges*

* Features only available for grid point clouds (structured). For unstructured point clouds, structure it by the Virtual Scan tool.

For Grid Point Cloud (structured) different point filtering tools are available.

Select the point cloud Right mouse button Filtering & Clustering

Restore the data previously pre-processed

Access at the 2D view of the point cloud

Fill the Invalid Points

Create a new simplify structured point cloud

Create a new simplify unstructured point cloud

Delete black points

Extract orientation and depth discontinuities

Simplify the point cloud

Create a unique unstructured point cloud from a group of structured ones

Filter the data with specific algorithms (see the related tutorial)

ResampleTo simplify a point cloud, enter the subsampling value desired.

A new structured point cloud will be created with a direct hyperlink to the full resolution point

cloud

Starting scan: Full resolution: subsample 1

New simplified scan: subsample 10

New simplified scan: subsample 10.

Direct hyperlink to the Full resolution scan

the Full resolution Point Cloud

Hyde black Points

Delete all of the black points

Starting scan: Full resolution: subsample 1

New simplified scan: subsample 10

Extract EdgesAvailable only if the point cloud has been pre-processed.

Orientation and depth discontinuities are automatically

extracted.

The discontinuities are extracted as polylines exportable

in .dxf format

3D density filteringTo simplify the point cloud according to a Volumetric Regular sampling

Change these values to increase the Cell size.

Higher is the Cell size, higher will be the

subsampling

Make single cloudCreate a unique unstructured point cloud from a group of structured ones. The final result is an

unstructured point cloud. You can set the final color and the final Subsampling.
