Abstract
Methods and systems for making measurements for eyeglass frames worn by human subjects include capturing, using a first digital camera module, a plurality of images of a head of a tested subject wearing an eyeglass frame. The plurality of images comprises a front view image and a side view image of a face of the tested subject. A second camera module is used to monitor a top view of the head. A computer module is used to process the front view image and the side view image. The front view image is used to determine a pupillary distance and a segment height, and the side view image is used to determine a vertex distance and a pantoscopic tilt.
