In the present scenario biometry is becoming a very important issue.Starting from the marketing domain where business man are trying to capture people emotions when they buy a product in the supermarket, till arriving to border security, or event security, where companies are trying to propose automatic solutions able to identify critical situations, and be sure that the identification of the person is reliable, also in presence of camouflages, the involvement of biometry is growing up very quickly, involving finger prints, iris recognition, voice recognition but especially human face analysis.In this specific domain many improvements have been done, due to the fact that face has many distinctive issues, and interesting results have been obtained, especially working with 3D models, rather than simple 2D images more fragile for the significant influence due to the working conditions, that are able to provide more reliable results and solve problems connected also with people age.Starting from these challenges, from the more easy availability of low cost 3D sensors, also located on commercial mobile devices, and from the experience acquired in the Politecnico di Torino 3D Lab (www.3dlab.polito.it),this papers wants to presents a review of the main outcomes coming from 3D face morphometric applications, providing a systematic synthesis of the different available methods and approaches in order to guide potential users in simply identifying the most suitable solution and technology in relation to the specific application and working conditions, providing some first issues on strengths and weaknesses.
