| Abstract: | The reverse engineering of geometric model based on product exemplar has become one of the research focuses in CAD/CAM field. The two key problems, surface digitizing and 3D reconstruction, in the reverse engineering are analyzed and studied for the MJ internal screw thread used in aerospace industry. A novel laser and fiber optic sensor for the complex thread surface inspection is proposed, and the measurement principle is described in this paper. Based on the cross sectional contour obtained by the sensor scanning, the 3D reconstruction can be implemented, and the preliminary experimental results indicate the availability and practicability of this method. |
