Abstract
3D measurement of human body has different application in bioengineering, and health areas. 3D models can be important to analyse hand function and behaviour and quantify pathology parameter, for example. The base of human measurement analysis is the use of a fast and non-contact system. This work aims to develop a stereoscopic measurement system by fringe projection making use of two digital cameras to acquire the images of a series of phase shifted fringes projected into the measurement surface by a DLP projector. A software was developed in order to process the images and using the concepts of phase unwrapping and epipolar geometry and then retrieve the 3D measurement of the surface under test. A plaster model of tooth arcade was used to test the measurement performance.
