Ground Point Filter
Plugin : SimpleForestNom de classe : SF_StepGroundFilter
Description
Ground Point Filter - This Filter estimates for each point the normal. The angle between the normal vector and the z axis is computed. If the angle is small, the point is detected as ground, if large the point is considered non ground.

- Uncheck to deactivate parameterization possibilities of this step. Only recommended for beginners: Activé.
- First the cloud is downscaled to a [voxel size] of 0.040 (m). .
- For each of the downscaled points its normal is computed with a [search range] of 0.200 (m). .
- The angle for each point between the normal and the z axis is computed and is not allowed to deviate more than [threshold]: 25.0 (°)..
