I want use darknet_3d in gazebo.
I changed darknet_3d.yaml file.

When I launched file, I got a below error code.. and doesn't show darknet_3d.

Do you happen to know fix it?
I used darknet_ros_3d.launch.

Below is my node

Hi @BamBamBap You can not use map as a working frame because the algorithm needs a frame whose axes are in the following way: X aiming to the front, Y aiming to the left and Z aiming to the top. This topic usually is "camera_link". Hence, if you want the coordinates based on the map frame you will have to do the transformation later
