GeoAdjust

The missing link between the survey grade GNSS drone and high precision photogrammetry.

GeoAdjust was developed to compute accurate camera coordinates on a UAV in flight. Timing adjustments, antenna to camera offsets, and drone attitude are taken into consideration to compute as accurate as possible the camera coordinates for importing into photogrammetry software.

Features:

  • Can load JPEG images from the DJI Phantom 4 Pro or DJI Phantom 4 RTK
  • Able to read GNSS coordinates from RTKLIB, or about any other post processing software able to export a text file
  • Camera event times can be read from the Emlid RTKLIB events.pos file, or the Phantom 4 RTK timestamp.mrk file
  • Can apply a time adjustment constant to correct any systematic timing error between the shutter and event time
  • Using the adjusted time will compute an accurate antenna phase center coordinate between GNSS epochs
  • Will apply a lever arm 3D rotational correction from the antenna to the camera based on the UAV attitude and XYZ offsets
  • Based on the above corrections a comma delimited file can by output for use in photogrammetry software
  • Error estimates of the camera coordinates can be included in the output file based on the GNSS quality, timing error estimate, and calculated speed.
