Hi Pawel,
I see, I suppose you want to get a file that is extracted from the .bin from Pixhawk log
to .txt with this format #name longitude/X latitude/Y height/Z yaw pitch roll Salt
If the introduction of the data Yaw, Pitch, Roll angles from the Log Pixhawk is impossible, then I ask only to generate: #name longitude/X latitude/Y height/Z in the file „file.txt” in the application Emlid Studio
Is the yaw. pitch, roll angles information recorded on the images?
We previously released support in Emlid Studio 1.8 to keep XMP tags from photo metadata that include yaw, pitch, and roll value. You can check about it in this thread.
