ObjectHypothesisWithPose with label #76

Open gbr1 opened 1 year ago

gbr1 commented 1 year ago

Hi, I'm working on wrapping edgeimpulse on ROS2.

It could be useful to have a string label parameter in the message type ObjectHypothesisWithPose because it often happen that you want to send also the label.

What do you think about that?

Thank you in advance!

I found another issue:

id in ObjectHypothesisWithPose is numeric (int64) for noetic but for foxy is a string
in galactic ObjectHypothesis is used instead

Please can you make unified? Thank you in advance

That change was intentional

gbr1 commented 1 year ago

@SteveMacenski so should be foxy updated to the galactic message version (the one with ObjectHypothesis)?

We don't usually unify message definitions across distros unless there is a very strong reason to do so. Because ROS messages are very brittle (non-identical message definitions cause all kinds of headaches), making breaking changes usually only happens between distros.

Future distros will all have ObjectHypothesis (unless another new change comes in), which allows a string. foxy will always have a string, noetic will always have an int.
