I have a pan tilt gimbal (tilt over pan i.e. tilt axis changes with pan.) for my camera and and i know the roll and pitch angle of the plane but in order to point the lens of the camera in nadir…Continue

Just update the Ardupilot firmware, newer versions already do what you want (Thanks to Greg !).
Just follow the instructions.

Greg Fletcher replied to Shivang Baveja's discussion pan tilt angle calculations from roll pitch angles"Shivang,
Actually this has all ready been done and is an Arducopter and Arduplane code in the AP_Mount.cpp. I will explain how it's done.
1) First start with the ahrs matrix(DCM) and transpose this into a new matrix. That gives the rotation…"

I have a pan tilt gimbal (tilt over pan i.e. tilt axis changes with pan.) for my camera and and i know the roll and pitch angle of the plane but in order to point the lens of the camera in nadir direction , i need to know the pan and subsequent tilt rotation i need to produce . I know the solution can be found using rotation matrices or quaternions but dont know exactly how to do it. Any suggestions are welcome.See More
