GAZE DETECTING APPARATUS AND METHOD

摘要

A gaze detection apparatus and method are provided. The method includes storing, by a controller, a reference gaze, a first reference vector, and a second reference vector. An image is then captured by an imaging device that includes user eyes. In addition, the controller detects central points of a pupil and an eyeball from the captured image and generates a gaze vector for one eyeball and a normal vector of a plane at which three central points are formed, when the three central points are detected. A first rotation angle and a second rotation angle are calculated by comparing the gaze vector and the normal vector, respectively, with the first reference vector and the second reference vector and a mean value thereof is calculated. Further, a gaze is then detected by rotating the reference gaze as much as the mean value.

1. A gaze detecting apparatus, comprising:
a memory configured to store program instructions; and a processor configured to execute the program instructions, the program instructions when executed configured to:
store a reference gaze, a first reference vector, and a second reference vector;capture an image including a user eye;detect substantially central points within the captured image of a pupil and an eyeball;generate a gaze vector for one eyeball and a normal vector of a plane at which three substantially central points are formed, when the three central points are detected;calculate a first rotation angle and a second rotation angle by comparing the gaze vector and the normal vector, respectively, with the first reference vector and the second reference vector and calculate a mean value thereof; and detect a gaze by rotating the reference gaze as much as the mean value.
