AVT camera not found

[llorban]

I am trying to run a camnode launch file. The launch looks like so:

<launch>
  <node name="Cam1" pkg="camiface_ros" type="camnode">
    <param name="device_guid" type="str" value="AVT-02-2020C-06767" />
  </node>
  <node name="Cam2" pkg="camiface_ros" type="camnode">
    <param name="device_guid" type="str" value="AVT-02-2020C-07056" />
  </node>
</launch>

I also tried using underscores.

And this is what the log looks like:

^[[0m[ INFO] [1531769131.179236474]: host timestamps OFF^[[0m
^[[33m[ WARN] [1531769132.255169176]: Selected camera AVT-02-2020C-07056 (-1) not found^[[0m

When running flydra in self-discovery mode, the cameras are found and detected as:

beelab@beelab:~$ rosrun ros_flydra camnode
[INFO] [1531768934.973439]: ROS name: /flydra_camnode
[INFO] [1531768935.003848]: choosing camera guid: Allied Vision Technologies-02-2020C-07056 (cam_id: 0)
[INFO] [1531768935.004234]: choosing camera guid: Allied Vision Technologies-02-2020C-07058 (cam_id: 1)
[INFO] [1531768935.004501]: choosing camera guid: Prosilica-02-2020C-06767 (cam_id: 2)

This Flydra instance is a fresh installation on July 16th.

Thank you!

Did you try using Allied Vision Technologies-02-2020C-07056 instead of AVT-02-2020C-07056 in your launch file? What happens if you do that?

[llorban]

That's what I had originally, but it didn't work either. When running the self-discovery process, I somewhere noticed that the cameras were renamed as "AVT" and underscores in the serial number. I tried that naming scheme but it also didn't work.

Going back to your original issue which is, as I understand it, "AVT camera not found". However, rosrun ros_flydra camnode shows that AVT cameras are chosen. For example: choosing camera guid: Allied Vision Technologies-02-2020C-07056. (I do not know where the Prosilica camera is coming from given that your launch file has only 2 non-Prosilica cameras in it.) What makes you think the AVT camera is not found?

If you save data, data from how many cameras is in the saved .h5 file? (e.g. using flydra_analysis_plot_timeseries_2d_3d <FILENAME.H5> https://flydra.readthedocs.io/en/latest/gallery.html#timeseries-of-2d-data )

[llorban]

Yes it's true that rosrun works fine, but I can't get the camnode launch file to work. I figure eventually it would be good to specify parameters which will need launch files instead of rosrun.

Yds I do get data from all 3 cameras in the h5 file.

In your launch file, you are trying to launch the program camnode from the package camiface_ros, but you want ros_flydra camnode from the ros_flydra package.
