摘要:Three-dimensional (3D) shape modeling is one of the most fundamental processes in CAD/CAM systems. There is a variety of methods to build 3D shapes for product design and manufacturing. The methods include defining a 3D object using solid or feature modeling methods, or building a 3D shape of the existing object using reverse engineering techniques. Image-based shape recovery techniques provide effective tools in reverse engineering to acquire 3D data of objects. This paper reports a simple method to reconstruct a 3D object from its 2D (two-dimensional) image for the product modeling. A method based on FTP (Fourier Transform Profilometry) phase analysis is proposed to measure the 3D surface of an object. The comparison of the FTP method with other methods is discussed and the process of the FTP method is provided. The experiment shows the accuracy and speed of the method.
