Traditional pupil localization algorithm can only be applied while head is stable or lighting condition is bright

so it is difficult to track human eye in multipose head movement. Aiming at this problem

propose pupil localization algorithm based on Kinect sensor

establish a 3D active appearance model（ AAM） to match bounding of eyes to obtain feature points

coarse positioning is carried out to segment eye

then pupil accurate positioning is carried out. Experimental results show that the proposed method can still track and locate human eye in condition of multipose and head is sheltered.
