Problem

High latency over DDS for high resolution cameras like zed2i

Solution

Component-based architecture for intra-process communication. Initially for marker_publisher

To do

  • marker_publish component
    • Camera info sub (availability issues)
    • Improved logging on start
    • Formatting
  • simple_double component
  • simple_single component
    • Dynamic parameter re-configures
    • Improved logging on start
    • Formatting
  • Convenience launch mixins (better other PR)
  • Examples / tests
  • Update the readme

Current components

component_types

Notes

  • Very happy to iterate and add for other nodes
  • Happy to add tests etc., improve upon launch files, write a bringup package
  • Need some quick feedback if this is desired by the authors!

Could you please give me a hand here @Noel215, thank you so much!

Hello @mhubii!

First of all, thank you so much for your contribution.

We understand in some instances, we might need components. As we can also maintain the current behavior. We are fine with the proposed changes.

sorry this PR is getting a little out of hand and might be difficult for review. I did some unnecessary formatting.

But now supports parameter re-configure and the current behavior should remain unchanged.

Happy to role back a little on the formatting changes and open new PR.
