  Hi Zahid Iqbal  It sounds as though what you are seeking might be the angle of a coordinate.  If so then the link below may be a helpful reference.

  MartyG,

  thanks, this is the same issue that I am dealing with. However, one answer provided actually finds angle between our point of interest, and another point in the image. (as far as I understood).

  I wanted to find a way to get this angle in reference to the camera coordinate system.

  The position and rotation of a coordinate in relation to the camera is usually referred to as the pose.  RealSense 400 Series cameras do not have built-in support for pose data (the retired RealSense T265 Tracking Camera model does).

   

  Aside from the link provided above, other approaches to detecting the angle by using RealSense depth in a trigonometry equation are discussed in the link below.

  The pose of objects can also be found with OpenCV using a SolvePNP algorithm.

  Another method is to use ROS.
