3D facial reconstruction based on structured lighting technique

This investigation describes three-dimensional (3D)human face recovery based on structured lighting technique. The aim of the paper is to reconstruct 3D model of human faceand evaluate accuracy of this method with the reference model that is created in 3ds-Max environment. The structuredlighting technique is a measuring method that recovers 3D shape of an object using projected lines pattern. Based on this method lines pattern is casted on simulated human face modeland image of deformed lines, captured with a CCD camera. In order to extract wrapped phase map which contains the heightinformation of human face, Fourier transform technique is applied on captured image. By applying 2D phase unwrappingtechnique, 3D profile of the human face is reconstructed. Finally in order to verify the accuracy of this method, the extracted profile is compared with the reference model. Theresults approve the validity and accuracy of this technique. The main advantage of the proposed method is requiring onlya single image as input. Hence it is especially suitable for analyzing dynamic objects. Furthermore, the method relies on very simple and low cost equipment.
