Abstract
To enable a more accurate estimation of the center of a pupil even in a situation in which it is difficult to capture an image of the entire pupil. An information processing device includes: an acquisition unit that acquires information regarding an iris in an eyeball; and an estimation unit that estimates a center position of a pupil in the eyeball on the basis of the information regarding the iris.
Claims17
An information processing device, comprising:
- a processing unit configured to:
- acquire information that corresponds to an iris in an eyeball;
- extract a partial image of a region of the iris based on the acquired information;
- generate a first polar coordinate image based on a polar coordinate transformation of the extracted partial image;
- and
- estimate a center position of a pupil in the eyeball based on the generated first polar coordinate image.
An information processing method, comprising:
- acquiring information corresponding to an iris in an eyeball;
- extracting a partial image of a region of the iris based on the acquired information;
- generating a polar coordinate image based a polar coordinate transformation of the partial image;
- and
- estimating a center position of a pupil in the eyeball based on the generated polar coordinate image.
A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by a computer, cause the computer to execute operations, the operations comprising:
- acquiring information corresponding to an iris in an eyeball;
- extracting a partial image of a region of the iris based on the acquired information;
- generating a polar coordinate image based on a polar coordinate transformation of the extracted partial image;
- and
- estimating a center position of a pupil in the eyeball based on the generated polar coordinate image.
