Abstract
Eye location is the precondition to monitor drivers fatigue state with the help of image processing technique. In order to achieve the purpose of detecting eyes location, a method was put forward to locate a driver's eyes based on infrared difference and gray integral projection. Firstly, two images for bright and dark pupils were collected for the pupil's different condition under the adaxial and abaxial infrared irradiation. Secondly, the collected parity frame images contained only binary pupil images by means of differential morphological processing. Finally, precise horizontal and vertical coordinates of the left and right eyes were obtained based on the vertical and horizontal projection on the left and right eyes respectively. Good results were achieved. The experimental results show that the method has high accuracy and real-time performance. This result is of great help to the next step of driver fatigue detection.
