1. A method for real-time monitoring of driver in a vehicle, the method comprising:
capturing, by a monitoring device and via a camera installed within the vehicle, at least one of a head movement, a steering direction, and a direction of gaze of the driver present in the vehicle;
determining, by the monitoring device, a Plane of Vision (POV) of the driver based on endpoints of each side view mirrors, a rear-view mirror, and bottom of a windshield of the vehicle, wherein the POV defines a 3D reference plane specific to a configuration of the vehicle;
dynamically determining, by the monitoring device, a Region of Interest (ROI) for the driver based on a bounding box regression model configured to update in response to the real-time direction of gaze of the driver and a direction of movement of the vehicle;
determining, by the monitoring device, a Line of Gaze (LOG) of the driver represented by a 3D directional vector based on the direction of gaze; and
identifying, by the monitoring device, a distraction level of the driver while driving the vehicle based on at least one of the POV, the ROI, and the LOG, using an Artificial Intelligence (AI) model.
