PRIETO, FLAVIO  e  SALAZAR, AUGUSTO. STEREO AND COLOR-BASED MOUTH ANTROPOMETRY. Dyna rev.fac.nac.minas [online]. 2010, vol.77, n.162, pp.225-236. ISSN 0012-7353.

A mouth anthropometry system using 3D images obtained from two views is introduced. 3D face features in the lips region are extracted from reconstructed 3D images, in order to compute some anthropometric measures, like: wide of the mouth, height of the mouth, length of the left and right sides of the upper lip, length of the lower lip, width of the philtrum, length and concavity of the Cupid´s arc. The anthropometric measurements obtained by using the system were compared against similar measurements obtained by 2D photogrammetry and by direct measurement on the face. Results show errors smaller than millimeter, with the advantage that 3D measurements have minor dispersion than the other methods.

Palavras-chave : Mouth anthropometry; 3D reconstruction; photogrammetry; computer vision.
