What Is ADAS Calibration and Why It Matters

ADAS calibration aligns cameras, radar, and LiDAR to the vehicle coordinate frame so automatic emergency braking, lane keeping, and adaptive cruise control behave as designed. When calibration drifts, safety functions degrade silently until an incident or audit exposes the gap.

Why calibration is not a one-time event

Vibration, thermal cycling, windshield replacement, and minor collisions shift extrinsics. OEM procedures assume periodic shop visits — fleets need continuous confidence signals between service events.

What gets calibrated

Windshield camera yaw and pitch, radar boresight, LiDAR registration, IMU alignment, and time synchronization across CAN and sensor buses.

Shadow-mode monitoring

NADIR ingests existing telematics and perception telemetry, scores residuals, and produces evidence-ready drift events without replacing OEM safety stacks.

FAQ

How often should ADAS be calibrated?

After windshield work, collision repair, suspension changes, or when drift scores exceed fleet thresholds.

Can calibration drift without warning lights?

Yes. Many drift modes degrade performance before dashboard faults appear.
