Why Fusion Matters

Beyond individual sensors—unified perception for safety-critical systems

Redundancy

Sensor Redundancy

Multiple sensors compensate for individual failures, ensuring continuous operation even when one sensor is impaired.

Confidence

Cross-Validation Confidence

Agreement between sensors increases detection certainty and reduces false positives significantly.

Coverage

Complete Coverage

Fill blind spots with complementary sensor data, achieving true 360° environmental awareness.
