Three-dimensional (3D) vision is undergoing a profound transformation. Recently, Zhoujie Wu and Qican Zhang from Sichuan University, together with Gunther Notni from the Fraunhofer Institute for Applied Optics and Precision Engineering IOF, published a review paper in Light: Advanced Manufacturing to systematically summarize over four decades of development in fringe projection profilometry (FPP) and reveal a paradigm shift from traditional geometric triangulation toward computational 3D imaging
