| Abstract(in English) | First Person Vision, which attempts to understand a person's behavioral intention, requires information on the person's state and on what the person is looking at. We propose an inside-out camera that simultaneously obtains image of one of the person's eyeballs and image of that person's visual field, and propose a method for estimating the person's gaze point based on the configuration of the camera. The inside-out camera uses a half mirror to capture the eyeball from the front and the person's visual field from the same position as the eyeball. The relationship between the gaze vector obtained from the eyeball video and the gaze point obtained from the scene video is expressed by a conversion equation, and the gaze point is estimated from the gaze vector by estimating beforehand the parameters of this conversion equation. In an evaluation experiment, we took scene video for both eyes when gazing at a certain landmark as evaluation data, and calculated the error between the position of the landmark in the scene video as the true value and the gaze point estimated from the gaze vector. It was found that the gaze point could be estimated with an average error of about 15 pixels. |
