RTK alignment problems

I am a little surprised you have not asked for this dataset to have a look internally, would you like to get this dataset to show us how this can be fixed?

Is it possible to reproduce this error on smaller part of your dataset? Then it would be nice to have it for test.

Guys for sure. RC is useless when it comes to RTK data / land survey purposes. Better use Metashape, Zephyr or ContextCapture

Try next:

  1. import photo dataset
  2. make sure that project coordinate system is WGS84
  3. select all photos
  4. under PRIOR POSE-> ABSOLUTE POSE select POSITION only
  5. under POSE ACCURACY select EDIT CUSTOM VALUE, and set them 0.1(m) for all direction
  6. start align

this is my workflow for DJI M3E, and it works like a charm. Let me know if it works for you

Guys
 For the sake of this magnificent software, there has to be a clarification.

We’ve had the exact problem when first utilizing a Phantom 4 RTK some 2 years ago. We’ve even went as far as sending the drone for repairs in case the RTK module was malfunctioning.

The entire problem lies within the (direct) inability (for the moment) of RC importing the camera position accuracies. Also the technical support team is aware of this problem for many months and still no (direct) solution is implemented.

What you need to do is actually relevant to what ArchCro is doing ie you need to import position φ,λ,h accuracies by using a flight log. You need to create a simple ASCII file from your jpg exifs (for example by using exiftool) and then select flight log import from the software.

You’ll know you’ve done this correctly when your photos have “edit custom values” in prior pose accuracy instead of “Global camera prior settings”. All other discussions that I see from technical support higher up are completely irrelevant regarding this simple “bug”.

Really inexplicable why no solution is being pushed for the above.

Can you make short tutorial for creating the flight log from exif?
