Prepare for dashcam road-facing ADAS calibration

In order to get started with road-facing advanced driver-assistance system (ADAS) features, which gather information about the road ahead and detect tailgating events, your dashcams first need to be calibrated. Calibration ensures the accuracy and quality of triggered events. The road-facing ADAS calibration process for almost any device on the market demands precision and a bit of extra time than other calibration processes might.  

For the Surfsight™ dashcam, the calibration process is dynamic. This requires recording several measurements related to vehicle size and the position of the installed dashcam, and then driving the vehicle on the highway for approximately 5 minutes before beginning configuration.

This article describes how to prepare for road-facing ADAS calibration.

To enable this feature, you'll need a few measurements that can be taken ahead of time. Record these measurements in centimeters or inches.

Important

The dashcam should first be installed at least 1.6 meters above the ground before beginning ADAS calibration. This is mandatory.

Next steps

Once you've recorded the measurements:

  1. Drive the vehicle at above 75 km/h for around five minutes. Images from this drive are automatically obtained and saved to be used later in the calibration process.

    Until your vehicle is calibrated, images are obtained and saved during every drive above 75 km/h.

  2. Calibrate the dashcam for road-facing ADAS. This includes selecting an image from your drive and inputting the measurements from the previous section.

    For step-by-step instructions of the calibration process, see ADAS calibration from the dashcam.
