I am new to ROS and RTT.
Given the Geometry_msgs/poseStamped message from two topics, how to calculate the transform T (Relative position) at time t1.
T^t1 = Relative_position (Pose_1^t1, pose_2^t1)
so that it can be used to locate the position of one frame from other in the same environment at time stamp t2.
Pose_1^t2 = Inverse_relative_position (T^t1, Pose_2^t2)
Precisely the calculation of Transformation equivalent to Homogeneous Transformation and using this transformation in Quaternion space to calculate the position of a point relative to a base frame.Wed, 03 Aug 2016 10:28:29 -0500https://answers.ros.org/question/241014/transformation-in-quaternion-space-for-geometry_msgsposestamped-message/
