3D Scanning System for In-Vivo Imaging of Human Body

Optical technologies for measuring the human body shape without contact have gained popularity in the recent years. In particular, techniques based on fringe projection have demonstrated a good performance for generating three-dimensional (3D) topographies of the human body. For the 3D digitization of the human body, the technique has found various applications in different fields, including relevant cosmetic and medical applications such as 3D back shape detection in scoliosis [1], 3D shape measurement of pectus excavatum [2], 3D intra-oral dental measurements [3], or 3D measurement of the topography of human skin [4, 5, 6]. In the latter, optical measurement of the skin surface by means of fringe projection provides a less invasive, faster and more accurate result than the obtained with traditional methods established in the cosmetic industry based on skin replicas of silicone, which are applied along several minutes on the person, and therefore are more sensitive to errors associated with unintentional movements of the person due to breathing or muscle contractions.
