What Is ADAS Calibration?

ADAS calibration is like giving your car’s safety systems an eye exam. Just as humans need their vision checked regularly, these systems need to be calibrated to ensure they’re seeing everything correctly. Calibration makes sure all the cameras and sensors are pointed in exactly the right direction and are measuring distances accurately. ADAS calibrations are critical for ensuring the reliability and precision of the ADAS system.

There are two main types of calibration: static and dynamic. Static calibration happens in a controlled environment, like a shop, using special targets and precise measurements. Dynamic calibration requires driving the vehicle under specific conditions to help the systems adjust themselves. Many vehicles need both types to work properly.

Meeting OEM Standards

ADAS calibration must adhere to strict OEM (Original Equipment Manufacturer) standards to ensure that each sensor is positioned and calibrated to provide accurate readings. Meeting these standards is crucial for several reasons:
