Blaze Camera not being found by ROS2 node about pylon-ros-camera

[jitaxis]

Update:
When I got the above error I was running it in a docker image.
When I run it on my host PC the ROS node can find the camera.
This doesn't solve the problem due to it still not working in the docker environment. I can run the pylon viewer in the docker image.
Does anyone have thoughts on what I can look into?
@FrancoisPicardDTI Do you have any thoughts on my situation?

Hello @jitaxis
It is then surely due to your network and docker configuration with respect to it.
I cna't help you much about the docker image but do you use a static ip address for the blaze?

Hi @FrancoisPicardDTI ,
Yeah i have setup a static ip for the camera. I covered most of my setup in the first post on this issue, if you need other info.
I have also got the pylon viewer working in my docker container which i thought would mean the network setup was fine?
Any thoughts on what could be the difference between the pylon viewer and the ROS2 node when running in the docker container?

Hi @jitaxis
No sorry, nothing comes to my mind. I am not a huge user of docker but someone from the community may be able to solve this problem. Try not specifying the user_id. The drive will try to connect to the first available camera.

I have tried that, sadly still didn't work.
Thank you for the help anyway. I'll look into it a bit more.

Hi @jitaxis
Maybe you can send me your docker files, or at least a sub part of them, so that I can test on my side?

Hi @FrancoisPicardDTI,
I have cut down the version of the dockerfile, I tested it and the same issue is happening so it should be good for you to test on.
I use a compose file to build and run my dockerfile.
I have also mounted the pylon SDK instead of copying it to save room for the zip file. The same thing happens whether it is mounted or copied into the image.

You will need to build using:
docker compose build
In another terminal run:
docker exec -it cutdwn_image-base-1 /bin/bash

You will need to source and build the ros2 environment in the terminal.

test_ws.zip

Let me know if you can find anything.
Thank you for the help.

Hi jitaxis,

Have you tried to set the environment variable GENICAM_GENTL64_PATH within the container?

For example, for the Dockerfile:
ENV GENICAM_GENTL64_PATH=/opt/pylon/lib/gentlproducer/gtl:$GENICAM_GENTL64_PATH
or within the container:
export GENICAM_GENTL64_PATH=/opt/pylon/lib/gentlproducer/gtl
