Kinect on other master
Hi, I install hector_slam_example package on my raspberry and i remove rviz node from launch file because i don't have rviz on my raspberry. Now, i want to run rviz with my PC to visualise hector slam data of my raspberry. when i run rostopic list on my PC, i receive all topics of raspberry but i cant visualise my caméra (just black image) i found in RVIZ no image receiver§ Is there any solution please?
Assuming you get data (check with
rostopic bw /your/image/topic), what happens if you runrosrun image_view image_view image:=/your/image/topicon your pc?when i run the first command, i receive nothing, and when i run the second commande, i receive juste a new window empty. what can i do in this case? i had a problem when i try to install rviz on my raspberry, i receive error that it depends of liburdfdom-world0.2. i don't know if this is the problem
Are the topics actually being published on the RPi? (Check with
rostopic hz). If they are, but you aren't receiving them on the computer, then I'd suspect a networking problem.when i run
rostopic hz, i receive justsubscribed to [/camera/rgb/image_color]Is that what you receive when you run
rostopic hzon the RPi? Then that indicates your nodes on the RPi aren't even working, and your issue has nothing to do with the fact that you have multiple computers, and likely has more to do with hector_slam on the RPiso what can i do?
The title and tags of this question are likely misleading for what your actual problem is; people are unlikely to chime in with anything useful. I'd start by working on making sure all of your sensors are working with the RPi, if that leads to new questions, then ask new questions.
