| Abstract | Generally it is difficult to get a 3D model from its 2D images. However, if the object is symmetric and its photograph is taken in appropriate perspective, then it is possible to extract pertinent 3D information from its 2D images. In this paper, a reverse engineering method to derive the 3D surface model from 2D photographs is introduced. Through a case study, the entire process from photo taking to 3D model making and subsequent rapid prototyping of a model car is introduced. The techniques and related problems of reverse engineering and rapid prototyping are discussed and the future research direction is proposed. Introduction By combining reverse engineering, CAD system and rapid prototyping technology together, a rapid product development system can be formed. This system can accelerate the iterative design process from initial conceptual and aesthetic design, product prototyping, and performance testing to model modification. Much work has been done in the area of reverse engineering, such as techniques using laser scanner, CMM, structured lighting, moire interferometers, etc. A comprehensive summary on these approaches can be found in [1]. There are two ways to reconstruct a 3D model from its 2D images according to the types or different features of 2D images. One approach uses 2D images from medical CT, MRI or industrial CT systems. Each ofthese images presents one intersection layer of the 3D object. The 3D solid model of an object can be reconstructed from a large amount of this type of 2D images. The 3D model obtained possesses both exterior and interior features of the object. Extensive research has been done using this approach[2J[3l . Another approach employs 2D photographic images or images of an object taken for different angles. The 3D model can he reconstructed based on one or more of this type of photographic or perspective images. In this case, only the surface or external features of the object can be captured. Generally it is impossible to get a unique 3D model from the 2D images because of inadequate information. However, if the object is symmetric and its photographic image is taken from a perspective view, it is possibleto extract necessary3Dinformationfrom its2Dimage. In this paper, a 3D-model reconstruction process based on the 2D photographic images is introduced. The integration of the reverse engineering method and rapid prototyping technology |
