Message You need to utilize clouds with the prequesitions:
  1. The center of the cloud is near the origin (max 50m), no georeferenced clouds allowed. No real world height allowed or at your own risk. The underlying point cloud library operates with float not doubles and point transformation tend to have therefore pretty fast floating point issues. Just follow this advice if you do not understand the reason ....
  2. I reach good runtime for plots smaller than 40m. I know the segmentation time increases exponentially with the radius and running the pipeline on hectare sized plots seems impossible without manual interaction.
  3. Beware if you try to model exotic trees (not expected in Euorpean NFI) I know buttress trees are expected to have issues with the underlying RANSAC principle during geometrical fitting.
  4. Be aware to observe carefully if you model trees with points larger than ~20 mio points. PCL routines using an Octree can fail here.

I checked for the preconditions named at 1). SimpleTree steps still do not perform as expected or is crashing

  1. Check if for each input result only one group is selected.
  2. Save the input cloud as xyb
  3. Produce a minimal running example with the test cloud which causes the crash or unpredicted behavior
  4. Make a well formated forum post. You enrich the post with the saved script from 3) and the cloud from 2).

For utilizing TLS scans a QSM method has been adapted to work on plot level. The whole plugin was developed utilizing source code from an open
source tool named SimpleTree ([[http://www.simpletree.uni-freiburg.de/]]). This standalone tool is unsupported since the core was integrated in
the Computree platform. Still the mandatory citation for utilizing this plugin is:

Two earlier published manscripts exist as well, the second one is mandatory to cite also if you use the test data which was published there:

Additionally from the following publication was adapted:

To support the core team (Alexandre and Michael) of Computree the best peer-reviewed resource might be this, as it describes steps included in the pipeline:

In addition the plugin steps rely heavily on the point cloud library ():

and the OpenCV library ([[http://code.opencv.org/projects/opencv/wiki/CiteOpenCV]]), which you might also want to use to give credit to the people working on those projects.

As soon as my crown segmentation algorithm and the advanced QSM method is published I will give you more citations. In case you submit a manuscript results produced with the plugin clearly mention the version of the release.

SimpleTree Plugin

The SimpleTree plugin is developed by Jan Hackenberg the DIABOLO project ([[http://diabolo-project.eu/]]) - working package (WP) 2.2.2

DIABOLO has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 633464.
Working package 2 has the generale purpose of Harmonizing growing stack, biomass and carbon estimation.
