Abstract

Two main problems currently face the developers of reverse engineering systems. The first is the time consuming digitization of 3D data. The second is the conversion of copious amounts of 3D digitized data into a concise data format exportable to CAD/CAM packages. Reverse engineering can be described as the automatic resolution of these problems. By combining the use of both a CCD camera and a 3D laser scanner, these issues can be tackled. The CCD camera is used to locate the object in the scan space, so that the laser scanner path can be programmed. Also, preliminary segmentation of the 2D image can be sued to identify individual surface segments to which a 3D laser scanner can then be directed to digitize. This extracted information can then be exported to a CAD/CAM package for the manipulation by the end user.
