Tried the available CITY dataset and I don't get even near the results as from Agisoft or Pix4d . With RTK pos: - RMS of 3D horizontal error: 0.535 m - RMS of 3D vertical error: 4.740 m With RTK pos and rotation from EXIF(results in 18 photos lost): - RMS of 3D horizontal error: 0.080 m - RMS of 3D vertical error: 0.120 m With GCP(category full): - RMS of 3D horizontal error: 0.028 m - RMS of 3D vertical error: 0.008 m With GCP(BASE point only horizontal adj): - RMS of 3D horizontal error: 0.026 m - RMS of 3D vertical error: 0.007 m With GCP(BASE point as check point): - RMS of 3D horizontal error: 0.104 m - RMS of 3D vertical error: 0.186 m BASE XY error: 0.559m & Z error:0.491m So it seems at least with this dataset and DJI camera results using REACH RTK are poor. It may be related to fact that dataset has poor overlap and also that Contextcapture doesn't handle rolling shutter distortion.
