PROBLEM TO BE SOLVED: To provide a sight line measurement method using a corneal surface reflection image, and a device for the same, which can perform sight line measurement without irradiating near infrared rays and performing calibration.SOLUTION: A sight line measurement device using a corneal surface reflection image, comprises: an eyeball image-capturing device 18 for capturing an image of an eyeball; an environment image-capturing device 19 for capturing an image including a gaze object; an eyeball model generation part 30 for generating an eyeball model from the eyeball image; a corneal surface reflection image extraction part 31 for extracting a corneal surface reflection image, which is reflected on a surface of a cornea, from the eyeball image; a tangential plane spreading out image generation part 32 for generating a tangential plane spreading out image in which distortion is corrected by spreading out the corneal surface reflection image into a plane; and a gaze point measurement part 33 for measuring a gaze point by performing the matching between the tangential plane spreading out image and the environment image including the gaze object. |
