Studies Measuring the Rotation Angle of the Driver's Face Method based on Three-Dimensional Image Measurement

Abstract

Among existing head orientation methods, two-dimensional image measurement is commonly is utilized. How- ever, it can be easily affected by environmental light. Besides, the angle of rotation could be too wide to measure. To avoid this, this study uses three-dimensional image measurement which is based on stripy light to collect three- dimensional data of human face, and there by head orientation can be detected by analysis. This essay takes advantage of the human nose as a feature point, and puts forward a method to detect the peak point of the nose from the wing. Finally, the head orientation can be detected through the nose information. It uses human head model as the measuring object, makes up experiment equipment based on visible light and infrared rays. Experimental results based on infrared rays within both 50 degree left and right prove that the proposed method is effective.
