Data Annotation Pipelines
Human-in-the-loop and model-assisted systems that convert raw video, sensor streams, and robot logs into training data.
Direct answer
What is Data Annotation Pipelines?
Human-in-the-loop and model-assisted systems that convert raw video, sensor streams, and robot logs into training data.
Definition and scope
Human-in-the-loop and model-assisted systems that convert raw video, sensor streams, and robot logs into training data.
Annotation platforms combine video labeling, segmentation, 3D/LiDAR tools, temporal tracking, QA workflows, and active learning.
Why it matters
VLMs, VLAs, and world models need aligned labels: objects, actions, intent, time, language, gaze, depth, and failure states.
How it works
Annotation platforms combine video labeling, segmentation, 3D/LiDAR tools, temporal tracking, QA workflows, and active learning.
Beginner learning path
Start by labeling object tracks and action segments in a short manipulation video, then add language and outcome labels.
