6.3. Camera positions converter
Writes the camera (photo) positions of a DJI flight in the format a photogrammetry package imports, in EGSA87 or WGS84, with or without accuracies.
6.3.1. Source
- DJI PPK result
cameras_EGSA87_full.csvfrom the DJI PPK tool. It holds both EGSA87 and WGS84 positions. (The shortcameras_EGSA87.csvhas no WGS84 columns and can only give EGSA87.)- Drone MRK file
The drone’s own on-board RTK positions from the flight folder’s
.MRK, for flights flown with network RTK and not post-processed. For EGSA87 output choose the transformation and geoid: with HEPOS network RTK use HEPOS and the HEPOS geoid. On the reference flight these positions came within a few centimetres of the PPK result.

Heights: EGSA87 output has the orthometric H (as cameras_EGSA87.csv),
WGS84 output the ellipsoidal h. Set the photogrammetry project’s vertical
reference to match.
6.3.3. Options
Write accuracy columns, at least (m) – the per-photo standard deviations, each raised to at least this value. RTKLIB’s and the drone’s own values are optimistic (a few mm); 0.01-0.02 m keeps the photogrammetry adjustment from treating the cameras as fixed.
Only fixed positions – leaves out photos whose position is float or single.
