Voronoi Based Tree Segmentation

Plugin : SimpleForest
Nom de classe : SF_StepSegmentationVoronoi

Description

Rather than computing the Voronoi regions for seeds, distance for the input points to the clustered seeds are computed.If a closest point pair between input and seeds has distance smaller than a threshold, the input point gets the ID of its closest seed point.

Paramètres

Paramètres de pré-configuration (non modifiables une fois l'étape ajoutée) :

  • Uncheck to deactivate parameterization possibilities of this step. Only recommended for beginners: Activé.

Paramètres de l'étape :

  • The cloud is scaled along the z axis with a [factor] of 0.3 ..

  • If an input point has a distance to its closest seed point smaller than [threshold] 0.7700 (m)..


it gets the according seed segment ID.
