HEAD UP DISPLAY WITH EYE TRACKING DEVICE DETERMINING USER SPECTACLES CHARACTERISTICS |
摘要 |
Embodiments relating to determining characteristics of eyeglass lenses are disclosed. A head-mounted display device comprises a camera communicatively coupled to a computing device and including an optical axis having a center point. Light sources are configured to emit light rays toward the lens to produce lens glints. The light sources are in a light source plane that is spaced from a lens plane by an offset distance of between 8 mm and 12 mm. The light sources are either spaced vertically from a line perpendicular to the light source plane and extending through the center point by a distance between 13 mm and 53 mm, or spaced horizontally from the line by a distance of between 13 mm and 80 mm. Lens characterization program logic identifies an image location of each lens glint, and outputs an estimated lens shape model comprising the one or more lens characteristics. |
