hey,
I wrote this comment under another topic but it seems better to write it separately here…
I am trying to view the depth map using zed ROS wrapper program but I am getting an error.
I followed the Jetsonhacks tutorial on youtube and also the steps on GitHub but I can’t get the depth map
what may be the problem?
this is the steps that I did:
ubuntu@tegra-ubuntu:~$ mkdir catkin_ws
ubuntu@tegra-ubuntu:~$ cd catkin_ws
ubuntu@tegra-ubuntu:~/catkin_ws$ ls
ubuntu@tegra-ubuntu:~/catkin_ws$ mkdir src
ubuntu@tegra-ubuntu:~/catkin_ws$ cd src
ubuntu@tegra-ubuntu:~/catkin_ws/src$ catkin_init_workspace
