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