I have 3D world points of an object as well as its image point. I have passed these into CalibrateCamera API and I am not getting right translation components and rotation matrix which would be transformed and used in opengl.

As I am new to opencv, Can we use CalibrateCamera without chessboard.

maybe i misunderstand it, but you usually calibrate your camera once using a chessboard or similar.

the goal of it is to get the intrinsic camera params, not the translation to the resp. chessboard

later, you can use the intrinsics with solvePnP() to find arbitrary 2d -> 3d correspondances.
