RTK drone images – model tilted 90° after alignment – recommended settings?

Hi everyone,

I’m working with drone images captured with RTK enabled (so the photos contain accurate georeferenced EXIF data).

When I import the images into RealityScan and run the alignment, the reconstructed model is rotated approximately 90 degrees (tilted on its side), even though the drone coordinates should be correct.

I suspect this might be related to:

  • EXIF orientation data

  • Coordinate system settings

  • Prior pose accuracy settings

  • Georeferencing or alignment configuration before processing

Before running alignment, I would like to better understand the correct workflow for RTK images.

Are there any recommended tutorials, guides, or best practices specifically for:

  • Importing RTK drone images

  • Setting prior pose accuracy

  • Choosing the correct coordinate system

  • Preventing model rotation or axis misalignment

Any advice or documentation would be greatly appreciated.

Thank you!

Hi Christina,
I suppose there are no recommended settings. Each dataset is slightly different. What were you alignment settings? Do all images have the proper coordinates? After import, are the images placed properly on the map view? Do you have also GPCs for this dataset?

All available tutorials are on our YouTube channel and there are some also there on EDC in the learning section.
