In the last years, the advent of computational power for calculations purposes have a great impact in the optimization of automatic industrial process relating to computer vision, machine learning, robotics and autonomous machine decisions. In this context, the fast topographic analysis of 3D objects ranging from milimeters to decimeters plays an import rol in autonomous industrial process. From the Optics, the fringe projection profilometry has been a cheap and versatile tool for this purpose. In this work, we realize an reverse engineering of these techniques found in the literature in the last decades. We build an adquisition system and developed some Python code for the image reconstruction for objects no found in the literature.
