MEASUREMENT METHOD AND SYSTEM OF VIEWPOINT POSITION

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring a viewpoint position in a three-dimensional space with a level capable of measuring eye movement, by imaging both eyes with one frame.SOLUTION: Provided is a method for measuring a viewpoint position by imaging eyes of a subject. The method comprises: an imaging step for imaging both eyes with one frame; a visual line analysis step for analyzing an image acquired in the imaging step, and determining respective visual line directions of eyes by a pupil position shape and reflectance position shape; and a viewpoint position specification step for determining an intersection of the visual line directions.SELECTED DRAWING: Figure 1
