Moving objects routine classifies groups of points that are captured from moving objects. It can be used for mobile laser data sets. The routine requires that data from multiple lines or scanners is available.
The routine classifies groups of points that are captured at one moment of time and at another moment of time, when the area was captured by another scanner or in another line, there are no points at the same location but point from behind the moving object.
The routine requires that points have been assigned to groups using the Assign groups command or corresponding macro action.
|From class||Source class(es).|
|Select Classes||Opens the Select classes dialog which contains the list of active classes in TerraScan. You can select multiple source classes from the list that are then used in the From class field.|
|To class||Target class.|
|Time difference||Minimum time difference between points on the moving object and points from behind the moving object. ??|
|Search radius||3D radius around each point within which only points of the same group can be located. Points on a moving object are considered to belong to the same group. A group is classified if there are no points from another group or without a group number falling within the given search radius. ??|
|Inside fence only||If on, points inside a fence or selected polygon(s) are classified.|
