Do you already know the translation and rotation? If so, then you could use static_transform_publisher to publish the transformation into TF. Or if you just want the transformation, then create two matrices T and R and calculate A = T*R using C++ or NumPy.Fri, 06 Jul 2018 13:40:29 -0500https://answers.ros.org/question/296242/find-transformation-matrix-between-two-frames-in-which-there-is-first-rotation-by-some-euler-angles-and-then-translation/?comment=296571#post-id-296571Comment by Reamees for <p>I want to find transformation matrix between two frames in which there is first rotation by some euler angles and then translation.</p>

If you just want to know a transformation between two frames that you already have then the easiest solution would be tf_echo.
