Publish only a selection of ZED ROS2 topics

[robinvetsch]

We have four stereo cameras that we start via the ZED_multi node. Is there a possibility in the ROS2 node not to publish certain topics that we do not need and thus reduce the computing power somewhat?

Many thanks for a hint.

Hi @robinvetsch
Welcome to the StereoLabs community.

This is a duplicate thread:

Publish only a selection of ROS2 topic of ZED stereo node

The ROS 2 topics are only advertised. They are NOT PUBLISHED if they are not subscribed to. For this reason, if you reduce the number of published topics, you do not obtain a reduction in the computing power.
