I don't have much experience with rqt but you may need to install a plugin (maybe this one?)
Alternatively try rviz for visualizing image topics. Run rviz2
in terminal.
How do I install that plugin, though. I can't find any information about installing plugins online.
I too don't have experience with rqt plugins. I'm afraid I can't help with this one.
As Mostafa mentioned rqt_image_view
should help.
In my case installing and compiling rqt_common_plugins
and image_transport_plugins
using rosinstall_generator helped. These are included in the PKGBUILD of mine for Turtlebot3 development.
Much easier approach is to compile them in a workspace and activate the workspace. They should be then visible in the rqt.
I have a /video topic, but when I open RQT using
ros2 run rqt_gui rqt_gui
, and go toPlugins > Visualisation
, there is no option to show images:The option is there when using the docker image
ros:galactic
, but not when installing from this package. What am I doing wrong?
