Sensor Stream Synchronizer

Software componentCognitionCognition & Memoryarc:SensorStreamSynchronizer

A buffering component that aligns multimodal sensor streams to common timestamps, holding early data until all modalities for that time are available.

Responsibility. Aligns sensor streams to common timestamps before fusion.

Also known as: Synchronized buffering

Direct neighbourhood (hover for relationship types)

sends data to dynamic

Multimodal Fusion Engine Ch1.4

Design guidance

MUST align all modalities to a common timestamp before fusion.

Quantitative guidance

As stated by the sources; verify before use.

Even single-frame misalignment across LiDAR, camera and radar can degrade object detection accuracy by up to 88% and tracking by 73% (Ch1.4).
