Outline of Final Research Achievements |
In this study, we developed the "peripheral vision camera" which is a device that accurately measures the peripheral visual field of a human, using corneal surface reflection analysis technology. This device uses the principle of finding the angle between the gaze direction and the scene point at each image point of the scene camera based on the light reflection model. We develop a technique to measure the peripheral vision characteristics of a person in real scenes.We first developed a high-accuracy image registration algorithm between the corneal images and scene images. In this method, the initial position is aligned by projecting the scene image and the surface reflection of the eyeball onto the three-dimensional ray space, then, by performing the detailed registration using the initial result, accuracy of accuracy of 1 degree or less is achieved did. By using this, it was possible to estimate the peripheral visual field of a person with high precision from the cornea image camera.
