Mission planning for vertical surfaces
Ground Control Software
I will give a short demonstration of four common (DJI-based) ground control software: DJI GO 4, GS Pro, Map Pilot, and Pix4Dcapture. For the most part, flight planning with these software is completed on site, in the field.
I have been following the workflow described in the USGS’ “Unmanned Aircraft Systems Data Post-Processing Structure-from-Motion Photogrammetry” document to process imagery captured with the Warnell drones.
The general processing outline is as follows:
- load photos (aka cameras)
- align photos (build sparse point cloud)
- optimize alignment
- error reduction
- build dense point cloud
- build dem
- build orthomosaic
- export dem/ortho/las
No deliverable for this lab.
