<h5>5.2.1 DMS calibration</h5>
<p>After the DMS channel is opened, the camera will be calibrated automatically every time the camera is turned on and off, you need to make sure the face is centered and aligned.</p>
<h5>5.2.2 ADAS calibration</h5>
<p>Firstly, draw the red cross label at the middle point on the ADAS phone calibration interface, as shown in the figure below; then install the camera in the middle of the vehicle to ensure the camera's line of sight can cover the road; then adjust the camera's angle so that the center point of the cross label can be aligned with the far vanishing point where the lane lines intersect; finally, fix the camera's position.</p>

<h5>5.2.3 BSD (front, rear, left and right blind zones) calibration</h5>
<p>First draw the area at the BSD screen interface, the red area is easy to trigger, the camera is installed in the middle of the vehicle to ensure that the camera's line of sight can identify the person; finally fix the camera's position can be.</p>
