Outlier Rejection
Outlier reject for GR-Features using points are available as follows:
-
Point List. The point list can be used for outlier rejection by setting a tolerance and using the Ignore >Tol button to ignoring points beyond a threshold. The list headers can also be used to sort the data and selections of points can be excluded manually using Shift or Control Click selection.
-
Graph. The deviation graph also provides direct access to included points and their relative deviation. Multi-select allows for quick removal of groups of points, all of which are set to “ignored” in the point list.
Outlier rejection for cloud based GR-Features are as follows:
-
Graph. The Point List is not available for cloud based relation- ships. Rather than keeping track of individual cloud points a reference cloud is used to build an analysis cloud. The graph provides a means to remove points from this analysis cloud. The graph functions differently as well in that it provides a his- togram display of the data and selection can be made of the data to keep with respect to sigma fit markers.
-
Proximity filter. In addition to simple geometry extraction the proximity filter can be used to edit the cloud points included in the fit by adjusting the filter settings and pressing apply. This will effectively delete the existing filter cloud and re-extract from the original input cloud using the new settings.
