Three-dimensional facial simulations and measurements: changes of facial contour and units associated with facial expression.

摘要: Recent innovations in laser scanning technology provide a potentially useful technique for accurate three-dimensional documentation of the face. In this study, linear and area measurements facial contour units have been recorded variety chosen postures using surface combined with lighting techniques on seven healthy volunteers three patients nerve paralysis. Three-dimensional measurement face was taken light scanner. Computer graphics were used to produce images constituted by highlights shadows, which emboss units. Then quantitative changes angles areas made analyze morphological accompanying expression. Changes widths cheek nasal found be associated dimensional imposed action underlying mimetic muscles. This system has potential value both dynamic monitoring evaluation contour, units, movement.
