Abstract

The reconstruction of three dimensional objects is an increasingly important topic in many fields. Many methods are used to achieve this but among them optical full field methods are used widely due to their advantages of non contact measurement operation, fast measurement speed and automatic processing. In the measurement process, a video projector projects a lines pattern on a test surface, and a digital camera capture the image of lines pattern on it. The height distribution of surface deforms the projected line pattern and modulates them in phase domain. By applying Fourier transform analysis and phase unwrapping algorithms, the 3D profile of test surface can be reconstructed. The purposes of this paper are digital reconstruction of complex object like human face and comparison of execution time among three different phase unwrapping algorithms applied to FTP method. In addition the accuracy of measurement based on this method is compared with rightful measurement.
