Perception System Validation Framework for ADAS Engineers
Validate ADAS perception outputs against ground truth data and document safety compliance
What You Can Do
You can quantify sensor fusion performance across object detection, classification, tracking, and localization using standardized metrics. The framework helps you identify systematic failure modes in diverse environmental conditions, document safety-critical gaps, and generate structured evidence packages for ISO 26262 and SOTIF compliance. This enables you to benchmark sensor configurations, define perception KPIs, and support regulatory submissions with rigorous performance documentation.
Features
validate perception outputs against annotated sensor data across multiple environmental scenarios
systematically identify and categorize perception system edge cases including occlusions, weather degradation, and lighting transitions
evaluate camera, radar, and lidar combinations with quantitative performance metrics
generate ISO 26262 FMEA and SOTIF evidence packages with structured findings
calculate and track detection accuracy, false positive/negative rates, and confidence calibration across semantic categories
structured methodology to investigate perception failures and trace issues to algorithm or sensor limitations
establish acceptance criteria and performance envelopes for development milestones
benchmark performance separately for vehicles, pedestrians, cyclists, traffic signs, and other detection classes
Example Output
Example 1: Detection Performance Report
- Object Detection Accuracy: 94.2% across 5,000 test frames
- False Positive Rate: 2.1% (acceptable threshold: <3%)
- Failure Mode Identified: 8.3% miss rate in heavy rain scenarios with lidar occlusion
- Recommendation: Increase radar weighting in sensor fusion during precipitation
Example 2: Root Cause Analysis
- Failure Event: Missed pedestrian detection at dusk (low light, 15° elevation)
- Root Cause: Camera saturation in 850-900nm near-infrared band, insufficient training data for twilight conditions
- Evidence: 12 similar failures across dataset with matching environmental signature
- Remediation Plan: Retrain model with 500+ dusk/twilight examples; add IR filter calibration
Example 3: Safety Compliance Artifact
- SOTIF Evidence Package: Perception system tested across 47 environmental operating conditions
- No hazardous failures detected in defined operating envelope (daylight, dry/wet roads, -10°C to +50°C)
- 3 known limitations documented outside ODD with mitigation strategies
- Confidence interval: 95% CI on detection performance metrics
