Computational array camera with dynamic illumination for eye tracking

摘要

Methods and systems for eye tracking are disclosed. One such method obtains a plurality of images of the eye from an array camera and detects glint positions and a pupil edge of the eye in the plurality of the images. A distance from the array camera to the pupil edge may be estimated based on the glint positions. A pupil image may be generated based on selected ones of the plurality of images, the glint positions, and the estimated distance to the pupil edge. A pupil center position may be determined based on the pupil image and the glint positions.

主权项

1. A method for eye tracking comprising:
obtaining a plurality of images of the eye from an array camera; detecting glint positions and a pupil edge of the eye in the plurality of the images; estimating a three-dimensional distance from the array camera to the pupil edge based on the glint positions; generating a pupil image based on selected ones of the plurality of images, the glint positions, and an estimated distance to the eye based on the estimated distance from the array camera to the pupil edge; and determining a pupil center position based on the pupil image and the glint positions.
