Moving Objects

This command filters points corresponding to objects which were supposed to be moving while scanning.

Requirements

Select one or several clouds containing scanning positions.

At least 2 scanning positions are required per cloud. In case of multiple inputs, the algorithm will process each one separately.


  1. Set the Resolution at 10 m. We advise to use a resolution 2 or 3 times bigger than the scan resolution at 10 m.

  2. Set the Threshold.


Technical information

The algorithm makes comparison between individual setups:

a) It stores foreground points for each setup ( 1 ) (a spherical grid is made according to Resolution at 10 m R).

b) Points which are background in other setups ( 2 ) mean there is a moving object in setup ( 1 ), unless both points are very close (Threshold T).images/download/attachments/137619906/cleanMovingObjectsDiag.png
