SphereFollowing Refit Cylinders

Plugin : SimpleForest
Nom de classe : SF_StepQSMRefitCylinders

Description

The steps imports a QSM and a cloud. Each cylinder of the QSM gets a point cluster. Each point of the input cloud is stored in the cluster of its nearest cylinder. For each QSM cylinder a cylinder refit is performed. If the new fitted cylinder does not deviate too much from the old one it is accepted as a replacement.

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 :


Cylinder refitting:
  • To even out the distribution and speed things up the cloud is downscaled first to [voxel size] 0.010 (m). .

  • Use as inlier distance [inlierDistance] 0.030 of cylinders. .

  • Fit a cylinder only with [min Points] 20.

  • Use [ransac iterations] 100.
