    The Challenge

    The client's autonomous trucking fleet was struggling with high false-positive rates in object detection during adverse weather conditions (heavy rain, snow, fog), leading to unnecessary braking events and safety disengagements.

    Our Solution

    We deployed a comprehensive data strategy focusing on edge case generation and targeted re-annotation. Using our proprietary synthetic data pipeline, we generated 50,000 photorealistic scenarios of trucks in extreme weather. We also re-annotated 200 hours of real-world driving footage with pixel-perfect semantic segmentation to better distinguish between harmless debris and actual obstacles.

    The Results

    After retraining the perception models with the enriched dataset, the client observed a 40% reduction in false positives and a 15% overall increase in object detection accuracy. The improved system performance allowed them to deploy their L4 autonomous trucks on two new commercial routes two months ahead of schedule.
