Automated updating of camera parameters for user-friendly driver monitoring system

This paper points to a component technology of driver monitoring system which has not been explored yet, namely, automated camera calibration. It proposes that the calibration should not be left to be done manually, as is the case now, but should be automated. In particular, this paper describes an algorithm to automatically update the camera parameters of the in-vehicle driver monitoring camera system using a planar symmetry, and discusses the accuracy and effectiveness of automated updating.
