Post processing
______________________________________
- Completely scripted using Helicon and Reality Scan (CLI) as external software
- All steps progress-monitored in web based UI.
- Camera poses were transferred from a scan of a calibration object (doodle ball), taken from the exact same VPs without focus stacking.
- Total post-processing time (unattended) : ~4h (of which focus stacking 1h10m).
