Abstract

This paper describes 3D measuring methods of head and eye positions for development of a tracking system. The authors prove that the 3D information about the eye position can be estimated from the camera image of a single camera. A 3D position is generally detected and measured using stereoscopic images of multi-lens camera system. This pair of stereo images allows us to obtain the 3D information about the object. However, it is possible to estimate the position of eyes using a single image without stereo images. We found the simple method for getting the 3D position of eyes using the interest points of both ends of eyes. In this method, the interest points on the strait line give us the estimates of the 3D position of both eyes. Moreover, we propose the measuring method using the result of a geometric analysis.
