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/i-am-new-to-ros-tf-i-want-to-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>ROS Transformation</p>

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