Client Background: A German autonomous vehicle technology company developing Level 4 self-driving systems required large-scale annotation of multi-sensor datasets combining LiDAR point clouds, camera imagery, and radar data for perception model training.

Challenge: The client needed to annotate 50,000 hours of synchronized multi-sensor driving data with 3D bounding boxes, semantic segmentation, lane markings, and traffic participant tracking while maintaining ISO 26262-compliant quality standards. Previous annotation vendors struggled with temporal synchronization across sensor types and inconsistent labeling taxonomy interpretation.

Solution: Hir Infotech deployed a specialized automotive annotation team of 120 specialists trained in ADAS labeling protocols. We implemented custom annotation tooling for synchronized multi-sensor labeling, comprehensive quality validation with automated consistency checks, and iterative feedback loops with the client’s ML engineering team to refine edge case handling.

Results: Delivered complete annotation of 50,000 hours within 4 months, achieving 98.9% annotation accuracy verified through independent validation. The client reduced perception model training time by 40% and improved object detection mAP scores by 12% compared to previous annotation datasets.

Client Testimonial: “Hir Infotech’s automotive annotation expertise transformed our perception development velocity. Their understanding of autonomous vehicle requirements and commitment to quality standards gave us confidence in our training data.”
