This video is an introduction to prescanning, postscanning, calibrations and ADAS systems for the collision shop.


NOTE: In the video, I mention sonar technology, which could be considered technically correct as sonar stands for sound navigation ranging; however, this term is generally used for under water applications. In reality, most sensors are radar (radio waves), lidar (light waves), or ultrasonic (high frequency waves, well above a humans threshold of approximately 20,000hz).
