Sensor Fusion Algorithm Validation for ADAS/Autonomous Systems
Validate multi-sensor fusion algorithms for autonomous vehicles and ADAS systems
What You Can Do
You can validate multi-sensor fusion algorithms (LiDAR, radar, camera, ultrasonic) by analyzing data consistency across sensor modalities, identifying edge cases and failure modes, and generating comprehensive test scenarios. The skill helps you detect asynchronous input issues, coordinate transformation errors, and sensor-specific failure modes while ensuring algorithms meet functional safety standards like ISO 26262 and ISO 21448.
Features
detects conflicts and inconsistencies between multi-sensor inputs and identifies reconciliation issues
maps sensor-specific failure modes (occlusion, weather effects, latency misalignment, coordinate errors)
creates edge case and adversarial test scenarios covering diverse environmental conditions
evaluates asynchronous input handling and latency compensation across sensor types
analyzes fusion method selection (Kalman filters, particle filters, graph-based) against requirements
designs validation test suites for algorithm updates and continuous safety verification
maps validation results to functional safety requirements (ISO 26262, ISO 21448)
Example Output
Inconsistency Report
- Issue: Camera detects pedestrian at 5m, LiDAR reports no object within 7m confidence threshold
- Root cause: Low-visibility clothing + LiDAR reflectance properties
- Recommended fix: Lower fusion confidence gate or increase sensor weighting logic
Generated Test Scenario
- Condition: Heavy rain + backlit pedestrian crossing at dusk
- Sensor behavior: Camera FOV degradation, radar multipath, LiDAR wet lens effects
- Expected fusion output: Degraded confidence, maintained tracking with increased gate
- Pass criteria: Detection latency <200ms, false positive rate <2%
Failure Mode Matrix
| Failure Mode | Affected Sensors | Fusion Impact | Mitigation |
|---|---|---|---|
| Synchronization lag >50ms | All | Position drift | Timestamp validation |
| Coordinate transform error | LiDAR+Camera | 15cm lateral offset | Calibration verification |
