CORNEA RADIUS ESTIMATION APPARATUS USING CORNEA RADIUS ESTIMATION ALGORITHM BASED ON GEOMETRICAL OPTICS FOR EYE TRACKING AND METHOD |
摘要 |
Disclosed are a cornea radius measurement algorithm based on geometrical optics for eye tracking and a device for measuring a cornea radius using the same. The device for measuring a cornea radius using a cornea radius measurement algorithm based on geometrical optics for eye tracking comprises a screen having a plurality of light source parts for outputting an infrared light source in a peripheral region; a camera for receiving an image of a user cornea through a reflection light source generated by reflecting the infrared light source on the user cornea; and a processing part for processing an image formed in a lens of the camera, wherein the processing part receives a first image according to the reflection light source generated by reflecting a light source outputted from a first light source part on the user cornea and a second image according to the reflection light source generated by reflecting a light source outputted from a second light source part on the user cornea, substitutes a cornea radius estimation algorithm programmed inside and measures the cornea radius of the user. |
