Development of an ultrasound based 3D facial scanning system

A low-cost ultrasound transceiver was used to scan the faces of two manikins. Each manikin's head was placed on a computer controlled turntable. The transceiver was mounted in front of the manikin's head at a distance of 20 cm and the scanning was performed from forehead to the chin by turning the table. After a single horizontal scan, the sensor moved down by 1 mm. Three dimensional views of the two faces were produced from the data, although the quality of scans produced in this study was coarse.
