| Abstract: | This paper discusses the advantages and disadvantages of some common methods about driver fa- tigue detection, and then proposes an improved method. Firstly, the method uses twice image projection and morphologic method to achieve precise eye location. Then, according to the difference of the width-height ratio of the eyes while opening and closing eyes, one new way for eye state identification is proposed. Final- ly, according to PERCLOS method, we can determine whether fatigue shows on driver. The algorithm can ef- fectively reduce the amount of calculation, and improve computing speed, and achieve high accuracy in the laboratory. |
