Thanks in advance to anyone who will help me with this matter.
I flew a Matrice 200 with ppk loki. Set up my base logging the static and I have sprayed 4 GCP’s to use as check.
Back in the office I processed the images in ASP suite and I run the initial processing.
I had a huge difference in 3D position (1m X 1m X 9m).
I can’t explain why.
I made sure base was on the right co-ords. I used the same projection, I checked the gcp’s on the field…
Camera calibration was correct
I asked a colleague to run the whole process again and he had the same error.
What can I have done wrong?
Then I went back to the field and picked up with RTK more natural features to use as gcp’s and check’s.
Re-run the initial processing, mark the gcp’s (8) and check’s (4) and reoptimize.
This time I have correct 2D position (within 50mm), but still height misclose between -0.319 and +0.189 with few check coming ok around 0.011 and 0.060…
I hope I explain myself clear enough.
