Sensor Fusion Data Annotation: How to Label Multi-Sensor Robotics Data

Sensor fusion data annotation is a critical process in multi-sensor robotics, involving the labeling of data from various sensors like cameras, lidar, radar, and ultrasonic devices in a synchronized and calibrated manner, rather than addressing each sensor separately. This process is essential for physical AI systems, including autonomous vehicles and drones, which rely on sensor fusion to perceive their environment accurately. Proper calibration and synchronization are prerequisites for effective annotation, as inconsistencies can lead to errors in the models trained on this data. Encord's platform supports this workflow by integrating raw sensor formats, offering model-assisted pre-labeling, and ensuring cross-sensor review, addressing the challenges of scaling annotation across vast volumes of data. The process is distinguished from standard sensor fusion by focusing on generating the ground truth for training algorithms, with public datasets like nuScenes and KITTI providing benchmarks for production-grade multi-sensor annotation. Quality control involves ensuring cross-modality consistency and addressing issues like occlusion, with AI-assisted techniques improving efficiency by pre-labeling objects for human review.
