Stem Filter by RANSAC fitting
Plugin : SimpleForestNom de classe : SF_StepStemRANSACFilter
Description
Stem Filter by RANSAC - Fits robust RANSAC cylinders into one meter height horizontal slices. If the cylinder per slice passes z axis check, its inliersare put into the output cloud. All other points are noise.

- Uncheck to deactivate parameterization possibilities of this step. Only recommended for beginners: Activé.
- First the cloud is downscaled to a [voxel size] of 0.010 (m). .
- For each of the downscaled points its normal is computed with a [search range] of 0.030 (m). .
- Into 1 meter horizontal slices a RANSAC cylinder is fitted with 0.10 (m). .

- The angle for each point between this cylinder axis and the z axis is computed and is not allowed to deviate more than [max degrees]: 25.0 (°)..
