3D Surface Measurement through Easy-Snap Phase Shift Fringe Projection

Abstract

Smaller objects reconstruction using three-dimensional techniques is one among the challenging tasks from the decade. Researchers in graphical designing and professionals of photography are continuously working on the reconstruction of 3D object techniques to meet the demand of real-time applications of almost all in every walk of real life. Reconstruction of 3D objects has a major role in the reverse engineering applications too. The major challenges in successful 3D object reconstruction are high computational costs and lack of accuracy. Fringe projection has come into view as a propitious 3D reconstruction mechanism with low computational cost for high precision and resolutions. It makes use of digital projection, structured light systems, and phase analysis on fringed images. Its performance is shown as acceptable in the research analysis carried out on the implementation of it and its insensitiveness to ambient light. An overview of some of the fringe projection techniques are presented in this paper and also propose a new simple fringe projection system, which can yield the more accurate and acceptable results with different objects.
