What problem does it solve?
Facilitate time-aligned processing of messages from multiple ROS 2 topics by using message_filters to synchronize callbacks based on timestamps.
Core Features & Use Cases
- TimeSynchronizer for exact timestamp matching across topics.
- ApproximateTimeSynchronizer for near-simultaneous messages with slop.
- Python and C++ usage examples for both subscription patterns, QoS considerations, and cached filtering.
- Common debugging guidance to ensure reliable data fusion in perception pipelines.
Quick Start
Configure a multi-topic ROS 2 node to subscribe to the relevant topics with message_filters.Subscriber instances, create a TimeSynchronizer or ApproximateTimeSynchronizer, register a callback, and process the synchronized data.
