LINE SCAN CAMERA EYE TRACKING SYSTEM AND METHOD

摘要

A system and method for determining positions of one or more eyes in a three-dimensional volume includes rotating an optical reflector within a linear field of view of a line scan camera to allow the line scan camera to capture image data of a two-dimensional projection within the three-dimensional volume, and processing the image data captured by the line scan camera to determine the positions of the one or more eyes.

主权项

1. An eye tracking system, comprising:
a line scan camera having a linear field of view and configured to capture image data within the linear field of view; an optical reflector disposed within the linear field of view, the optical reflector adapted to be rotated and configured, when rotating, to allow the line scan camera to capture image data of a two-dimensional projection within a three-dimensional volume; and a processor coupled to receive the image data captured by the line scan camera and configured, upon receipt thereof, to determine positions of one or more eyes within the three-dimensional volume.
