Facial Image Processing Technology - Detection of Facial Direction -

As an advanced active vehicle safety method, facial image processing technology has been developed for a pre-crash safety system(PCS).
In this approach, the facial direction of the driver is determined using images captured by a monitoring camera mounted on the steering column. Based on the relative position of the symmetry axis and the edges of the face, it can be determined whether the facial direction is frontal on non-frontal.
It then becomes possible to provide accurately timed alerts depending on the direction in which the driver is facing. The world’s first practical PCS based on this technology was released in 2006 by Toyota Motor Corporation.
