Camera coordinate system - math to convert to blender

Hi, I followed the “Camera Projections in blender” tutorial (https://www.youtube.com/watch?v=yq0XjvBlsiU) and I am able to get the camera orientations in an abc file in blender.

I noticed that RC allows exporting camera parameters in another format (xyz, head, pitch roll) but these don’t match what I see in the abc file in blender:

E.g. for one camera this exported csv file (registration export) I see this:
|x|y|z|heading|pitch|roll|
|-0.129|0.102|0.169|35.86|-32.60|-86.30|

The position matches exactly (with y and z flipped), but I can’t make sense of the rotation in this CSV file - do you have documentation on this, or how to convert these rotations to xyz euler angles?

Thank you

Hi luiz_gustavo_h,
RealityCapture and Blender are using various coordinate systems, so also the rotations will be different. To see the angles better you can use FBX format, but still it seems like there are some differences. I will inform our developers about this and create a bug.
Thank you for noticing.
