Thanks, I was going crazy trying to find a native way to do this. If someone knows of a native way, I 2019-09-06 10:25:32 -0600 marked best answer transformStamped to transformation matrix (python) This may be trivial but I cannot find it anywhere, can someone help me? Goal: Find a transformStamped by a tf2 transform lookup, then convert this to a matrix so I can multiply it. Something like the below: import tf2_ros import tf #(more code here, but not important to question) tfBuffer = tf2_ros.Buffer() listener = tf2_ros.TransformListener(tfBuffer) trans = tfBuffer.lookup_transform("gps", "base_link", rospy.Time.now(), rospy.Duration(0.1)) matrix = tf.transformations.translation_matrix(trans) # (More code after this point as well.)  Again, this may be trivial but I cannot find the solution to this nor a question that answers my problem. 2019-09-06 10:25:32 -0600 received badge ● Scholar (source) 2019-09-05 14:06:44 -0600 asked a question transformStamped to transformation matrix (python) transformStamped to transformation matrix (python) This may be trivial but I cannot find it anywhere, can someone help m 2019-09-05 07:46:27 -0600 commented answer ROS across machines: cant echo topics/visualize rviz (NOT DUPLICATE) See @gvdhoorn comment above and report back, I still feel this is the problem until we know for sure. 2019-09-05 07:44:26 -0600 edited answer IMU + Odometry Robot Localization Orientation Issue Four questions: 1): Do you have a second EKF estimating map_frame:?
