These covariance terms have 36-length of a list, so I think they correspond to [x, y, z, roll, pitch, yaw] terms row and column each other. I don't know how you got the value 29 and 21, you probably have also considered that the first index is 1, but you can have x (row number) and y (column number) from those formulas : So 29 is actually row 4 column 5 and 21 is row 3 column 3. to your account, Hello, we are trying to publish on a topic with type geometry_msgs/PoseWithCoviaranceStamped.
