Rail detection

This video is about how to extract a semi-automatically object type Rails as a 3D line feature using the 3dm_feature_extraction.
The extraction of the Rails will be saved to a pre-defined vector file.

1. Open the pre-prepared Mobile Mapping run
2. Set 3D Hover Preferences
3. Measure rails
4. Create a preconfigured line vector file
5. Set dataset to recordable
6. Save the rails measurements to the line vector file
7. Inspect attribute table
8. Optional : modify the default parameters of rails detection under the Detectors settings
