I want to use ZED camera for tracking AR tags.
Following the installation instruction , when executing the command “rosdep install --from-paths src --ignore-src -r -y” I see this error:
I built the package and when executing the launch command “roslaunch zed_ar_track_alvar_example zed_ar_track_alvar.launch”, I see this error:
ERROR: cannot launch node of type [ar_track_alvar/individualMarkersNoKinect]: ar_track_alvar
ROS path =/opt/ros/noetic/share/ros
ROS path =/home/hamid/catkin_ws/src
ROS path =/opt/ros/noetic/share
I have to state that there isn’t any problem with executing ZED-ROS-WRAPPER node. I’ve built the package before and everything works well with it. Also, ZED SDK has been installed correctly.
I am using “ZED” camera.
OS: ubuntu 20.04
GPU: NVIDIA GTX1050Ti
Can you help me with this issue?
