| 摘 要： | INTRODUCTION Geometric modelling is essential processing in computer-aided engineering (CAE) systems. Usually, the modelling of three-dimensional (3D) objects is embedded in a computer-aided design (CAD) system, which may take a huge amount of time to build entire models for CAE application. One option is the use of techniques of reverse engineering (RE) to build models from existing objects. Coordinate measuring machines (CMMs) are traditional RE tools used in the manufacturing i…

| Abstract: | This paper discusses current research and development of fringe projection-based techniques. A system based on Fourier transform profilometry (FTP) is proposed for three-dimensional (3D) shape recovery. The system improves the method of phase unwrapping to gain accurate 3D shapes of objects. The method uses a region-growing algorithm for the path prediction guided by the quality map to increase the recovering accuracy and provides a fast and simple tool for 3D shape recovery. The shape measurement and data recovery are integrated to offer a new method of 3D modelling. Examples are presented to verify the feasibility of the proposed method. |
