Compressed Image Transport in ROS 2

Source: ros2-copilot-skills compressed image transport skill

Why This Matters

Image streams can dominate network and CPU budgets quickly. Compression helps move vision data through constrained systems, but it changes latency, fidelity, and computational load in ways the rest of the pipeline has to tolerate.

Distilled Takeaways

• Compression trades image quality and CPU work for lower bandwidth.
• The right choice depends on transport constraints and downstream perception sensitivity.
• Not every vision pipeline benefits equally from compressed transport.
• Compression strategy should be part of the system architecture, not an afterthought.

Practical Guidance

• Use compression where transport is the bottleneck, not blindly everywhere.
• Measure latency and perception quality under realistic workloads.
• Keep topic naming and transport settings understandable to operators.
• Re-evaluate compression choices if model accuracy or network layout changes.
