Ocular rotation measurement device, ocular rotation measurement method, and ocular rotation measurement program

摘要

The eyeball rotation measuring device of the present invention includes a blood vessel position recognition unit and a first angle calculation unit. The blood vessel position recognition unit recognizes the position of the blood vessel in the white eye region in the eyeball image, and acquires information regarding the position of the blood vessel. The first angle calculation unit includes first information related to a predetermined blood vessel position acquired by the blood vessel position recognition unit during actual measurement of eyeball rotation, and second information related to a predetermined blood vessel position in the reference state. Based on the above, the eyeball rotation angle is calculated.
