VISUAL AXIS ANALYSIS SYSTEM AND VISUAL AXIS ANALYSIS DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a visual axis analysis system and visual axis analysis device, even when an object is present in environment unsuitable for imaging, capable of specifying a part of interest of a browser on the object.SOLUTION: The visual axis analysis system: acquires a scene image and a fixation point from a visual axis tracking device including a camera and a distance sensor (S11); extracts scene image feature points from the scene image (S12); acquires reference image feature points (S13); and associates the feature points to one another (S14). The visual axis analysis system: acquires a scene distance image from the visual axis tracking device (S15); extracts scene distance image feature points from the scene distance image (S16); acquires reference distance image feature points (S17); and associates the feature points with one another (S18). The visual axis analysis system designates one having more associations out of the scene image and the scene distance image, as a selection image (S20); creates a coordinate transform matrix for transforming coordinates of the selection image into those of the reference image or the like (S30); and transforms coordinates of fixation points of each scene image using the coordinate transform matrix to calculate association points on the reference image (S40).
