REARVIEW ASSEMBLY ADJUSTMENT SYSTEM

A system for calibrating a driver monitoring system in a vehicle comprises a rearview assembly comprising a housing, a mount secured to a vehicle surface, and a barrel extending between the housing and the mount; an imager disposed in the rearview assembly; a processor in communication with the imager; a memory comprising a file containing information on stationary landmarks proximate the imager; and a controller operable to: receive images of the vehicle's interior and calibrate the imager by identifying a substantially stationary landmark in a first image used during an initial calibration; wherein the controller is configured to re-calibrate the driver monitoring operations based, at least in part, on a detection of the substantially stationary landmark being in a different location in a second image relative to the first image. One of the ends of the barrel is connected with a moveable joint.
