Open hitmyself opened 1 month ago

hitmyself commented 1 month ago

When I run the following command,：

ros2 launch crazyflie launch.py

It gets:

[gui.py-5] Error:   TF_NAN_INPUT: Ignoring transform for child_frame_id "cf4" from authority "default_authority" because of a nan value in the transform (-0.007230 -0.012239 0.009829) (nan nan nan nan)

[gui.py-5]          at line 254 in ./src/buffer_core.cpp``

how can i solve this problem

Is the functionality affected? This seems to be some warning (even though it says error), that is most likely happening in single marker tracking mode (where quaternions are set to nan).
