Abstract:
A viewpoint position detection apparatus for detecting a viewpoint position of a person to be measured, and outputting viewpoint position information, comprising:infrared image capturing means for capturing an infrared image of the person to be measured; visible image capturing means for capturing a visible image of the person to be measured; detection means for detecting a pupil position of the person to be measured from the infrared image captured by said infrared image capturing means; template generation means for generating a template for pattern matching with the visible image captured by said visible image capturing means using the pupil position detected from the infrared image by said detection means; and matching means for detecting a viewpoint position of the person to be measured by pattern matching with the visible image captured by said visible image capturing means using the template generated by said template generation means, and outputting a result as the viewpoint position information.
