General / How is the roll, pitch,yaw defined?
« on: May 25, 2016, 03:26:58 PM »
Dear Agisoft team,
I would like to import a txt file in the reference pane with the full camera pose (position and orientation).
My orientation is defined in quaternions and I can convert it to any format, which can be used by Photoscan for image alignment.
I assume further, that roll, pitch, yaw are defined as euler angles. Thus, converting the quaternion to euler might be the way to go.
However, when I pass the euler angles (e.g. roll=z, pitch=x, yaw=y), (n DEG) the angle errors after the camera alignment process are very high.
* How do I map the euler angles( x,y,z) to roll, pitch, yaw assuming that my image local coordinate frame looks like this (z-front, y, down, x: right) : http://www.mathworks.com/help/vision/gs/triangulate_worldcoordinate.png
* If your roll,pitch,yaw is some sort of euler angles, is it defined as xyz or as a zyx rotation?
Thank you very much!
