Dear community,
I have a (silly?) question regarding my slanted output. I'm fairly new to CC and I ran into the problem just recently, since I use the Phantom 4 RTK. Prior to this my results were good. In the image below you can see an example, where the model is 1.5m higher on the left while in reality this isn't the case. I use acurate GCP's, in this case 5. I compared the results with pix4dmapper and there I was able to generate a good leveled model.
My workflow, that worked up until this point, is the following:
I used to work with M600 and obtained good results without any additional or alternative steps, but unfortunately this is not the case anymore.
Perhaps it has something to do with the fact that the Phantom 4 rtk has a new camera?
Any help is much appreciated!
Milo

As of CC U14 it is not using RTK positions correctly yet you have to reuse calibration.
Problem is that if using GCPs then RTK is not used. So if not reusing good calibration it tries to warp the model as-is on GCPs. It seems GCP are not used for camera calibration.
I didn't get it. Would be nice to test on some project if it even works wth RTK. Do you know if somebody confirmed that?
You can check on any project. The camera calibration before and after adding GCPs are the same even for models which were curved before. The warping on GCPs seems to be additional parameter.
Yes I do understand that Camera calibration is essential but I was asking if it is possible to run aerotriangulation with RTK and GCPs together? For e.g. I have one GCP for height and rest of polygon will rely on RTK picture pose, is it possible? Maybe there is a sequence of creating aerotriangulation first on RTK and run it second time with that one GCP?
this is precisely what i'm running into. Contextcapture need to find a way to use GCP and RTK selectively and work together
It is now possible in "Update 15"

fantastic! thanks for the reply.
