Abstract
A system for generating bodily measurements of a user appearing in video stream. The accuracy of the measurement is enhanced by performing a calibration to obtain a length per pixel coefficient and performing registration of an avatar of the user to a graphical target to position the user at the proper orientation. The calibration may be obtained by using measurement of the iris of the user. The registration may be obtained generating a three-dimensional spheroid corresponding to the head of the user and moving the spheroid in correspondence to motion of the head of the user.
