My project coordinate system is set to local:1-Euclidean. I exported a complete dataset, specifically exporting the XMP file and the Camera Alignment description files for X, Y, Z, Heading, Pitch, and Roll.
I analyzed the rotation values one by one and found that the rotation matrix described in xcr:Rotation in the XMP file does not seem to be convertible to the Heading, Pitch, and Roll rotation values in the Camera Alignment description file. I tried many calculation methods, but I couldn’t make the two transform into each other, and the values differed greatly after conversion.
Am I misunderstanding something here? I assumed that the rotations in xcr:Rotation are stored in row-major order. Below are my original files and data:

What are their specific calculation rules?
